Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

1.Ferro silicon is often used as deoxidizer in steel making.

2.Ferro silicon 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.Ferro silicon commonly used as a reductant in ferroalloy production and chemical industry.

4.In iron industry,it often used as inoculant and nodulizer and deoxidizer.

5. What’s more, 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.

6.Ferrosilicon commonly used as a reductant in ferroalloy production and chemical industry.In iron industry it often used as inoculant and nodulizer and deoxidize.

Q: What are the three types of commonly used cemented carbides?: ISO divides cemented carbide into 3 classes: P, K and M.P class (equivalent to China's YT class) carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials.

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: How to tell what is hard alloy and what is high speed steel?: Carbide and high-speed steel, grinding wheel spark identification, red spark is high-speed steel, no grinding wheel with hammer hammer, easily crisp alloy, also can use magnet experiment, carbide is not sucked, high-speed steel can suck.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.Is a kind of high speed steel tool steel with high hardness and high wear resistance and high heat resistance, and high speed tool steel or steel, white steel. High speed steel was developed by American F.W. Taylor and M. White in 1898. High speed steel has good technical performance, good strength and toughness, so it is mainly used to make complex cutting edge and impact resistant metal cutting tools. It can also manufacture high temperature bearings and cold extrusion dies. In the production of high-speed steel by melting method, after 1960s and the emergence of powder metallurgy high speed steel, its advantage is to avoid melting methodproduction caused by carbide segregation caused by mechanical performance and reduce the deformation of heat treatment.

Q: What are the cemented carbide coatings?: The hard alloy coating is used to form high hardness wear-resistant coating on the surface of metal, Beijing Naimo company according to the composition of the alloy is divided into:1.jp8000 spraying tungsten carbide coating2. nickel tungsten alloy coating3. cobalt tungsten alloy coating

Q: It is hard alloy steel: Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: How can I buy carbide die on the Internet? Who can help?!: The mould made from the same carbide alloy made from Zhuzhou will not be sold.

Q: 5 meters long hard alloy bars, where are they sold?: This should be hard to buy. You can call Zhuzhou diamond carbide group. If they don't, then there's no chance of it

Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!: Hard alloy is too high and can not be polished by ordinary metallographic sand paper. It should be put on the machine tool by diamond grinding wheel, and the cost is also very cheapReally manual grinding, then you can add grinding cream to try, but the efficiency is very low

Q: What kind of cemented carbide is used for processing HRC40 degrees stainless steel?: It is recommended to choose YS8 welding tool. Very good processing quality can be obtained.

Q: What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?: ISO (International Organization for Standardization) will be divided into carbide alloy P, M, K three categories, P class equivalent to China's YT class, the main ingredient is WC-TiC-Co;In order to be processed in different cutting conditions of material grade, in the P class with 01-50 number between that from the highest hardness to a series of alloys for maximum toughness between P30, roughly equivalent to the YT5 of our country;This kind of cemented carbide has the highest strength and best impact resistance in YT (P), but it has poor wear resistance. It is suitable for intermittent roughing of general carbon steel and alloy steel.
