products information

Our factory supply 75% 72% 65% 45% four grades of ferrosilicon.

Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.

Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.

High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing.

In the steel industry, one ton of steel consumes about 3 ~ 5kg75% ferrosilicon.

Melting point: 75FeSi to 1300 ℃

Q: suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?: Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced

Q: What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?: YG8.YG6 series alloys belong to class YG alloys. YG8 is softer than YG6 alloy.

Q: Carbide coated drill bit will reduce the service life after grinding, how to avoid?: 1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.3. the wear of drill bit belt has the most serious influence on drill bit life.4. so, when using the drill, pay attention to it:(1) the drill should be kept as small as possible at the top of the drill bit.(2) the spindle of machine tool has enough rigidity and precision.(3) the drill shall be replaced and sharpened when used.5., the drill can be re coated after grinding, pre treatment should be done before coating. To increase the coating effect.

Q: Carbide cutting insert: Brand in general can be found above, but you can also go to Zhuzhou tungsten tungsten alloy to see, they have good quality there

Q: What is the difference between the raw and recycled materials of cemented carbides? The more specific, the better: Raw raw materials are raw materials, recycled materials have been used, and then recycled and re produced, raw materials than recycled materials used, and more pure materials.

Q: What cemented carbide does 2gr13 use?: 2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.

Q: What kinds of carbide knives do you have? Write out its main functions and uses.: (2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.

Q: What is the difference between the production process of ferrous powder metallurgy and cemented carbide?: In 1890, the invention of tungsten powder, made by powder metallurgy, in the United States, laid the foundation of modern powder metallurgy. Around 1910, it has been made by powder metallurgy method of tungsten and molybdenum products, hard alloy, bronze bearings, porous filters, brush set, and gradually formed a complete set of powder metallurgy technology. In 1930s, after the advent of the vortex grinding iron powder and the carbon reduced iron powder, the iron based mechanical parts made by powder metallurgy have gained rapid development.

Q: Where does Tianjin sell yt30 carbide tool?: Now there are the same, express, everything is not afraid. I am the agent of Zigong the Great Wall brand cemented carbide, quality assurance, definitely authentic.

Q: Printing requirements for cemented carbide: Its disadvantages are: there are a small amount of pores and defects in the product, and the carbon content of the sinter will decrease.Hot isostatic pressing sintering in sintering with inert gas, liquid metal or solid particles as pressure transfer medium in each direction of the sintered body exert equal pressure, not even this can overcome ordinary hot pressing pressure is not uniform and the resulting product performance. The hot isostatic pressing of cemented carbide can eliminate the pores in the alloy and the drilling pool after sintering, and restrain the growth of WC grain. The Kennametal Inc installed the first heating chamber for 277mm * 1270mm in 1967. The temperature is up to 1500oC and the pressure can reach140MPa's hot isostatic pressing machine has taken the lead in successfully applying the technology of hot isostatic pressing to the production of cemented carbide. Since then, hot isostatic pressing technology has developed rapidly in foreign countries (especially in the United States).
