FeSi

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.

Application

1. Ferrosilicon 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.

FeSi For Metallurgical Deoxidizer

Q: Hard alloy is tungsten?: General tungsten cobalt alloy is mainly applicable to: carbide cutting tools, molds and mineral products.Tungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt.

Q: What is the resistivity of the yg13 cemented carbide?: Four, YG13 tungsten steel product featuresYG13 ultrafine particles and by using tungsten alloy in low pressure sintering, uniform grain distribution, good compactness, no pore free porosity and uniform microstructure and excellent wear resistance, 90.5HRA hardness, flexural strength up to 4000MPa and have high wear resistance, comparable to the quality of imported tungsten steel material, some performance parameters are better than similar imported tungsten steel material.

Q: Is there a material that is more wear-resistant than cemented carbide and has a relatively low cost?: If it is numerical control tool, it is more wearable than cemented carbide: ceramic, CBN, diamondAmong them, the lowest price of ceramics, diamond prices are highest

Q: There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?: Tungsten titanium cobalt carbide a tungsten titanium cobalt carbide consisting of WC%26mdash, TiC, WC and bonded cobalt metal or a multiphase hard alloy consisting of only WC%26mdash, TiC solid solution and cobalt. Cobalt content of alloy 4% ~ 10%, containing TiC5% ~ 30%, margin of WC, mainly used for cutting steel.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. There is no such term as brittle cemented carbide.

Q: What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: Y is the abbreviation of "hard". The letter behind is the abbreviation of metal material, such as "L" is "aluminum", "YL" is "hard aluminum". The number should be related to the alloy composition.

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: 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!: First of all, is the alloy itself if there are problems, product patterns, mainly to see the pattern is a kind of form, if a cluster or cluster, is generally the product of carburizing, such products also have a feature in 40 times under the anatomical microscope observation, can see the concave point, the because the graphite particles in the grinding conditions, free C from the alloy caused by the desquamation of this kind of products, should not be a problem after carburizing burnback.

Q: What is the difference between the production process of ferrous powder metallurgy and cemented carbide?: Powder metallurgy, powder metallurgy, has been in fact a long time ago. In early times, powders of gold, silver, copper and bronze were obtained by mechanical comminution and used as decorative coatings for pottery. In the second half of the eighteenth Century and the first half of nineteenth Century, countries such as Russia, England and Spain made sponge platinum particles from factories, and manufactured coins and valuable objects by hot pressing, forging and pressing, sintering and other processes.

Q: What are the carbide inserts on the turning tool welded to the handle?: The first copper burned in the post, and then the borax fell on the top, then put on top of the alloy blade, borax fell on the alloy blade above the flame cutting with money. Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly. Let him cool naturally,

Q: My uncle is a hard alloy round bar. Can you tell me where to use an alloy round bar?: I have some hard alloy round bars (tungsten steel) and high speed steel round rods (all used for cutting tools). Now I want wire cutting, laser, diamond, wire cutting
