Carbide Die is ten times the life of steel and even a few times, with a high hardness , high strength , corrosion resistance, high temperature resistance and low coefficient of expansion , usually cobalt- tungsten carbide . Carbide since the beginning of the 1920s , with its "widia" like the name of the diamond market since the German scientist by the invention , and the first production of tungsten tensile modulus get industrial applications , replacing the current price of expensive diamond drawing die .

Our Carbide started late , but rapid development . According to reports , at present, carbide die basically serialization and standardization. In recent years the development of the situation, the theoretical study of carbide tooling and design has a deeper and more science, applied more widely .

In the development of new alloy materials on behalf of a few years ago to drill for the hot iron and nickel . Metallurgical materials such as Hunan province developed the equivalent of YG, YG20, YG25 the strength and toughness of cemented carbide, received good results in for cold heading die , cold extrusion die and so on. Tianjin Institute on behalf of the iron-nickel carbide drill also developed a considerable YG1520 carbide die materials , standard parts in the roll forging , cold heading steel ball fairly with regard YG20 effect.

In recent years, new research is popular fine grain , ultra-fine grain , and even gradient nanocrystalline carbide and carbide . There are gradient cemented carbide composition gradient , gradient structure , in addition to the molten metal is also useful to produce osmotic gradient cemented carbide processing methods , such as the top of the gradient cemented carbide hammer .

Fine grain and ultrafine grain carbide also available, such as fine-grained YGS drawing dies while drawing <φlmm wire , is three times the normal drawing mode .

In addition, cast- inlaid carbide hot die , and achieved good results in terms of rolling and wire rod rolling .

Recently, Ganzhou Mining Authority for Chongyi County Keshu Ling tungsten mine mine geological environment governance projects conducted preliminary acceptance.

Chongyi County Keshu Ling tungsten mine mine geological environment governance projects, the central government prospecting and mining royalties and price projects with funding of 350 million. The governance projects by the Jiangxi Provincial Department, Jiangxi Provincial Department of Finance for approval. After the start of the project, has completed the repair of embankments 535.17 meters, 1.6 km river dredging, removal of waste rock and other construction waste 8.8 Articles content. After the implementation of the project, due to historical mining activities to solve the resulting waste rock spoil the river, riverbed, flood embankments destroyed, landslides risks and other issues, to ensure that the county shut down Guan Cun Town, more than 125 500 people life and property safety.

Tungsten scrap prices continue to hold steady. Currently scrap tungsten drill focused on the purchase price excluding tax mainstream 185-188 yuan / kg, imported scrap tungsten blade 176-180 yuan / kg, domestic waste tungsten blade 167-170 yuan / kg, scrap wire drawing dies 178-181 yuan / kg Waste pure tungsten 213-221 yuan / kg. W ≥ 70% concentrated in the purchase price of the grinding material mainstream 1.75-1.8 yuan / kWh; 50% <W <70% ,1.65-1 .75 yuan / kWh; 30% <W <50% ,1.45-1 .55 yuan / kWh, steady .

In the mining and cargo operators reluctant to sell emotional support, tungsten ore market is becoming strong. Tungsten scrap market continues to maintain a steady trend, height tungsten scrap material resources are still tight, the price is relatively strong, scrap tungsten steel business mentality calm, the price adjustment will is not strong, steady watching the majority. Tungsten scrap market is expected to more than short-term steady trend will continue.

[International] overseas markets were mixed tungsten City. 23 evening MB ferrotungsten Rotterdam quote 41.5-42 USD / kg tungsten, down $ 0.4-0.5; paratungstate Europe quoted 365-380 U.S. dollars / metric ton, $ 5 on expensive exploration; quotation 362-370 U.S. dollars / metric ton, continue steady. Expected short-term overseas tungsten Costco will continue to narrow adjustment.
