Product Description:

Ferro Silicon Description 

 Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz 

(or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound 

into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking. 

 

Ferro Silicon Application

 1. Fesi 75% is often used as deoxidizer in steel- making.   

2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel. 

3. It can be used as a reductant in ferroalloy production and chemical industry. 

4. In iron industry it can be used as inoculant and nodulizer.

Q:Which is better, cemented carbide, YG8 and YG20?
YG8 and YG20 are two grades of cemented carbide. They are not good or bad. It depends on what occasion you use
Q:Hard alloy die mold grinding angle how slim
Place the grinding head on a drill press or polish on an electric tool. Can the hard alloy die is caught in the lathe, grinding with diamond file.
Q:What is the difference between hard alloy steel and high speed steel?
1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)
Q:Can ceramic tools process cemented carbides?
No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
Q:What type of carbide for punching dies? Better. Where can I buy it?
Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
Q:Compare the advantages and disadvantages of high speed steel and cemented carbide
Hard alloy powder is: high hardness metal carbide to micron order, with cobalt, molybdenum, nickel and other binder, under high temperature and high pressure sintering temperature. The carbide content in hard alloy than high-speed steel, high hardness, good abrasion resistance (HRC75--80).Hard alloy red hardness can reach 800-1000 degrees.Carbide cutting speed is 4 - 7 times higher than that of high speed steel, and cutting efficiency is highThe disadvantage is that the bending strength is low, the impact toughness is poor, the brittleness is great, and the impact and vibration resistance are low
Q:The requirement of machining thread holes on carbide is higher
The shrinkage coefficient must be taken into account, but the technical requirement is quite high and the molding is difficultIn the processing of hard alloy threads, if high precision, small hole, can be used in EDM processing, now EDM with C axis, don't work fixture, the thread can play any pitch, as long as the processing thread electrode is.
Q:Is Zhuzhou the largest cemented carbide producer in Asia?
Of course, yes, or how could the 601 factory be so famous? That's the old military enterprise. It's the hard tool factory now. I hope it can help you!
Q:What are the features of cemented carbide YG8 knives?
Density: 14.6-14.8; hardness HRA:90.5; flexural strength, Mpa2300High bending strength, shock resistance and vibration resistance is better than YG6. It is suitable for low speed rough machining of cast iron, non-ferrous metals and their alloys, and non-metallic materials
Q:What are the well-known brands of cemented carbide materials at home and abroad?
Domestic mainly Zhuzhou, the other side, the 601 factory is the best made in Zhuzhou. That is, the Taiwan side of the spring insurance is equal to the domestic better, and even better point is the German Lu Sheng Fort I know these, ha ha!
