   By TZM (molybdenum lanthanum alloy) and TZM molybdenum alloys in 1000 ~ 1800 ℃ high temperature performance and corresponding organizational studies. The results showed that: the case of less than 1400 ℃, lanthanum molybdenum alloy has high strength and ductility combination of properties when the temperature is higher than 1400 ℃, the molybdenum alloy tensile strength decreased lanthanum, molybdenum, lanthanum alloys also have significant ductility decreased. With the temperature increase test, TZM alloy reduced tensile strength, ductility but elevated molybdenum alloy TZM, which is opposite and molybdenum lanthanum alloys. Meanwhile, regardless of strength or ductility, TZM molybdenum alloy compared to the same temperature lanthanum alloys have a distinct advantage. Organization observations show that: The two molybdenum alloy recrystallization starts at 1100 ℃, has been extended to 1550 ℃, and its elongated recrystallized grains are showing the organization, which is significantly different from pure molybdenum recrystallization state equiaxed grains

The advantage of the graphite electrode is the processing easier

 high metal removal rates, and loss of graphite. Therefore, more and more plants die and switch to renounce the use of copper electrode graphite electrodes. Some shapes of the electrode can not be made ​​of copper, but graphite is easier to shape. Heavier copper electrode (graphite weight of copper 1/5), not suitable for processing of large electrodes, which is one of the reasons instead of graphite electrodes.
Mold factory to switch from the copper electrode graphite electrodes, graphite need to understand how to use the materials, as well as many other factors to consider. Graphite is divided into different levels, in particular the application using the appropriate grade graphite and machine parameters can achieve the desired results. Such as the use of graphite electrodes machine operators use the same settings with copper electrodes, the results are disappointing. Because the melting point of copper is 1083oc, and the melting point of graphite 3400oc appear. Graphite electrodes can withstand greater machine setting conditions. These settings metal removal rate of the calculated loss amount and graphite. If the need for strict control electrode material, the graphite electrode can be located in non-roughing loss state (loss of less than 1%). But copper electrode is not used.

Graphite electrode machining easier. Graphite milling metal processing speed than other 2-3 times faster. And does not require additional manual handling. However, the copper electrodes require manpower fell mill. Graphite electrode Molybdenum tube high speed machining centers, high efficiency, and no dust problems. Choose the right tools and graphite hardness can reduce tool wear and breakage of the electrode. Compare graphite electrode and copper electrode general work and found the graphite electrode milling time faster than 67% of the copper electrode, and electrical discharge machining is 58% faster. Significantly reduce the processing time, increasing productivity and reducing manufacturing costs.

Quartz infrared lamp structure and characteristics of

Quartz infrared lamp is capable of emitting infrared spectrum 0.75 ~ 3μm, size, power range of different tubular lamps. It usually consists of a tubular quartz glass tube, internal helical filament composition. Filament to the annular ring support bracket, and with the glass wall separated to prevent the filament in the working state of the high temperature caused damage to the wall. Both ends of the quartz tube in the flame burning melting state clamp flat sealed tube filled with inert gas such as argon to protect the filament at high temperature is not oxidized. Sealing bits Molybdenum crucible filament is connected to the external electrodes. Commonly used form of a square ceramic head lamp, metal flake lamp, small ceramic cylindrical lamp and other forms. Part of the outer wall of the lamp can be sprayed ceramic directional infrared energy reflected reflective coating to further improve the heating efficiency of the lamp.
    Infrared lamp to achieve 0.75 ~ 3μm infrared spectrum, the filament temperature is usually needed to reach above 2000 ℃. Therefore, in addition to the tube filled with inert gas to protect the filament will not be oxidized under high temperature, the need to fill the amount of halogen cycle gas. Halogen cycle gas at a high temperature of the filament can be evaporated out of the tungsten atoms, while in terms of the filaments has been combined with the hot tungsten filament atoms released back to further prolong the life of the filament.

    Infrared lamp is radiated (Radiation) manner the energy directly to the object to be heated, so the heating fast, high thermal efficiency, and does not have any polluting substances produced, is a very clean and environmentally friendly way of heating. And because the thermal inertia of the filament is very small, it can be very easy to achieve fast and accurate temperature control.

    It is understood that sharp Bronte Lighting Co., Ltd (CREATOR UV & IR LIGHTING CO.LTD.) Is a very professional manufacturer of specialty lighting products, and its products include quartz infrared lamp, quartz UV lamp, UV sterilizers, electronic ballasts and many other varieties. The production of quartz infrared lamp variety specification is complete, and the lamp, long life, excellent quality.

    These infrared lamp can be widely applied to food heating, PET bottle blowing, footwear (glue curing), printing, electronic industry (such as wave soldering machines), the semiconductor industry, indoor and outdoor heating, car paint, powder coating, color coated board production line and many other fields, and have had a very good application effect.

Synthesis of superhard materials exploration carbide anvil

Anvil proper use of
A) six anvil precise adjustment
    The processing of the press-cylinder cumulative error is critical. Some scholars believe that such adjustments can be set eccentric presses itself neutral, which can only say that when there is no way to remedy, especially the larger presses cumulative alignment errors will also increase. But when we can do it in the press processing within its design limits, do not relax with eccentric adjustment requirements.
Anvil and down, left and right, front and rear three groups should be adjusted to a central point, or shear forces will play a larger role.
    2) warm-up before starting the anvil
    Where have to be energized before starting Preheat 15min or longer, then formal synthesis. Experience has shown that it is important to improve the life of the top hammer way. Pressure working pressure generally 1/3 or so. Now there are more than one hour warm-up, it is no longer necessary for the proper warm-up to the micro-hot.
    3) set aside anvil pressure
    Before each stop, do not put pressure on the press all relieved, the pressure chamber opened. One day or several days after synthesis, a top hammer dozens, hundreds or thousands of times continuous heating, cooling, boost, buck. Thermal stress, compressive stress repeated the role, then suddenly the synthesis chamber open to its own release stress, often caused by the steel ring off the front edge of the top of the hammer head; even if no U-turn, life is not long.
This general reserve pressure gauge is about 20 ~ 30MPa.
    4) Synthesis of non-stop
    Some believe that the press after starting work, to a certain stage should be stopped to "rest." This view is very wrong, the problem is still to see the results. Once we advocate boot, unless a special machine, therefore, not free to stop. This is because it boost heating; cooling down, the whole process has resulted in a dynamic equilibrium. This dynamic equilibrium more stable life for the better improve anvil, this movement is not easy to obtain homeostasis, once diamond high yield, good quality and low consumption.
    5) heated anvil top plane may not have pyrophyllite powder
    It is very easy to happen in the event of burns easily anvil, causing small cracks, and finally to the top hammer to shatter.
    6) a reasonable plug
    I had mentioned previously prevent the "point" contact to "face" contact. Later, workers changed the whole steel plug, not combined with Molybdenum tube  I believe that this change is good, but with the changing cavity, plug the "face" should also be somewhat larger, otherwise they become a "point", while achieving its purpose. Large cavity in the study powder catalyst synthesized block begins with cavity much, much bigger plug plug, the authors suggested that with a small plug, and this opinion was not accepted, but then a small plug does have excellent practice sex, so quickly across the country, this is a good example. Plug cankered easy to burn anvil, with pyrophyllite powder is easy to burn anvil, all with out a reason.
    7) Cooling anvil
    Speaking before changing the steel ring design, enhanced cooling problem. But not too cold. Too cold will cause the rod temperature difference is too large, steady increases have affected the quality of diamond. Here again is the fuel tank cooling issues raised, the available copper coils; also used car water cooler, so that the whole system presses the temperature down to ensure the stability of the performance of the press, which in the hot summer or the South is more important .

Attention needed to promote green lighting

Sixties of last century, the international lighting products for personal possession of national sandblasted tungsten target  show that every 30 to 40 Chinese people can be assigned a light bulb, and the advanced countries a foreigner was able to get more than 20, the data greatly shocked and hurt all of us engaged in the development staff's inner light. At that time the Chinese people at home and even light bulb is broken, you must also take the damaged light bulb can not be used to store confirmed, to allow the purchase of new the old, so that today it seems very common fluorescent lamp, at that time a distinction between rich and poor families symbol. This is just an example of their lives, from the industrial, cultural and scientific frontier point of view, much of the work carried out are also behind the light source be severely constrained. As a film shooting power source, then the use of a light source, the volume is much larger than basketball and requires four people to lift the its lamps, halogen lamps and abroad is not only light, the effect is much better than the domestic. Foreigners boast to call this new light source is "atomic light", meaning China's science and technology capacity is then impossible to manufacture out, this is undoubtedly the lack of lighting technology demeaning. Even more difficult to accept is that many imported advanced scientific instruments and equipment are required with light, once the light damage needs to be replaced, my throat often been abroad for this unreasonable restriction. For example, an instrument of about 10 million dollars, about $ 500 bulbs, if they can not produce light damage, harsh raised abroad will have to re-buy the whole set our new device, and then be able to rationing alternate light source, the light source of the defect then we will not be consideration does not bear a great loss.
   To this end, Professor Cai Zuquan lead the whole of science and technology workers set a goal, we must adhere to independent research and development, the successful development of new sources to fill the gaps in the country, so that our light source technology in its rightful place internationally without being bullied. Under the leadership of Professor Tsai along with everyone working hard. Those days was a hard and busy, no summer vacation and holidays, eating and sleeping are laboratory-home, often tired, they slept in the lab, woke up and then went dry. High-pressure mercury lamp was studied when the new light source products, research and development process encountered a big problem is that the quartz glass and metal vacuum seals need to be very thin molybdenum film, but then there is no domestic companies can produce it. Tsai will be thick molybdenum heat after the Heat, the same as on the iron like a blacksmith hammering, often knocking hundreds of molybdenum slice, to get a few slices can meet the requirements of molybdenum sheet, so we break metal and quartz glass vacuum seal storm, after a year of unremitting efforts, the first domestic high-pressure mercury lamp only finally developed. The news was in the country, especially in the Fudan University has aroused a great response, it is China's high-intensity gas-discharge light sources of the birth and progress of the foundation, in 1965 the school membership meeting held in Fudan University, the school put pressure mercury lamp high in the school auditorium the most prominent position.

Analysis of tungsten market

  tungsten carbide inserts ore production enterprises, metallurgical plants and many other learned that the current recovery in the region tungsten ore production situation is not very good, only a small part of the enterprise in the production. The current harvest in the region is very difficult, individual producers are reluctant sellers, and individuals are willing to sell to sell in kilograms, and the periods of no more than 300 kg, a boss who woo information, said: Guangxi this the situation is very common, they have no way, because now it is too difficult to close the mine, on the kilogram sold in the 54 yuan / kg, these mines are all hand-dressing individuals, according to this price calculation, which is 54,000 yuan / ton (excluding tax), equivalent to 97 cents / metric ton, the price is too scary, good luck you can receive 65 degrees above the mine, so it will not lose money, and if bad luck may be only about 60 degrees , this would all see their eyesight, the boss also revealed recently from Hunan, Jiangxi, Guangxi and other regions to the owner receiving a lot, and some local businesses have to go and do the smelting of ore acquisition. For this, insiders pointed out that this situation can be seen everywhere, and now the government is very strict checks on non-ferrous metal piece, Hunan, Guangdong, Jiangxi, Henan, Fujian and other provinces to resume production situation is not very satisfactory, the current tungsten ore prices are steadily rising, leading to the purchaser had four active sourcing, now is still relatively optimistic about the market outlook.

Quality Inspection Center of tungsten and rare earth samples enabled the closing

 National Tungsten wire and rare earth products quality supervision and inspection center in Gan County, Jiangxi Ganzhou Economic and Trade Commission of the "National Quality Inspection Center of tungsten and rare earth samples received" recently established. The center consists of Jiangxi University and Jiangxi Ganzhou joint venture. Samples received after the establishment of a number of companies submitted sample as long as you can to collect samples, you can send samples for the enterprise to save time and improve efficiency.　

tungsten market Analysis

 "Where Yu Information - Tungsten eletrode sub-station" 2009-7-28: Recently tungsten prices, regional enterprises to resume production situation is different, specially today where yu information contact areas in Hunan Leiyang tungsten producers.
   According to Fan-yu information understood to resume production in the region is not a lot of tungsten mining companies, most are still in a wait state. According to a recently resumed production of the individual person in charge, and now most of his or her own individual goods, every day there are many buyers come to us receiving, but the existing ore stockpile are priced at current prices will certainly be sold loss, and this year the production of goods, according to the current situation, the market outlook will likely rise a little, so we do not rush to sell, but only in the hands of cash flow to only consider a little. Our side of the black tungsten mainstream offer is 57,000 yuan / ton (excluding tax), wait for some time to consider such goods whether to sell, since we now will not be considered.
  Where yu information is estimated that current export prices, steel prices began to rise, many manufacturers have spotted the opportunity, is also very optimistic about the market outlook, so now not to consider shipping, the entire domestic sentiment is very strong, there will be a small margin estimated price rise.
