The BEST price & quality for various Ferro Silicon 75%, 72%, 70%, 65%, 60%, 15%,45% etc.


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 is the base material of carbide saw blade?
Carbide saw blades include the kinds of alloy cutters, matrix materials, diameter, tooth number, thickness, tooth shape, angle, aperture and so on. These parameters determine the machining ability and cutting performance of saw blades. In selecting the saw blade, it is necessary to select the saw blade according to the kind, thickness, sawing speed, cutting direction, feeding speed and width of saw.
Q:What kinds of carbide cutting tools are used in the 16 and 20 manganese grinding of the lathe?
YG6A is not suitable for processing steel, especially manganese steel. It is used to process cast iron, which is easy to accumulate.With YS8, you can.
Q:Purchased welding wire, carbide grinding head, diverter, bolt, gear, etc.,
Carbide grinding head, drill bit, tap, is a tool of low value, easy to wear goods.Welding wire, flux, welding rod and protective welding gas belong to raw material
Q:Hard alloy and cast iron join together, what glue is good?
Why use glue only? Recommend the use of welding, as welding tool is not the same as you can.
Q:The difference between cemented carbide and tungsten.
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.
Q:What is the hardness of YG8 cemented carbide?
YG8 is a tungsten cobalt type material.Good wear resistanceDensity / (g/cm3): 14.5-14.9Hardness (HRA): 89Flexural strength (sigma bb/MPa): 1500Impact toughness K/ (J/cm2): 2.5
Q:How are carbide cutters made? 20
CNC carbide cutter is used to hard alloy powder and powder metallurgy mould after sintering, the hard alloy blade (blank, can not be directly used), then after grinding the surface and edge (this can be installed on the cutter head, and also can be used) in coating the surface to improve its wear resistance, have finished milling blade.The blade is machined with a special blade grinder.
Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?
(1) mechanical wear: the abrasion caused by the friction between the chip and the cutter front, the surface deformation of the workpiece and the sharp friction between the cutter face, called mechanical wear.When the cutting temperature is not too high, the mechanical abrasion caused by this friction is the main cause of tool wear.(2) thermal wear: when cutting, because of the severe plastic deformation and friction of metal, the cutting heat makes the blade hardness decrease, and the wear and tear caused by cutting performance is called thermal wear.It is recommended that the Santak wick tool be used to solve the wear problem.
Q:The welding welding hard alloy cutter, should use what type of flame why
With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be
Q:Why is Zhuzhou cemented carbide plant called (601) 80??
Construction 601 is for military services, and now the city has changed. Now there are many military factories are code names, only know its code name, I do not know what it is to do.
