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.

Q:What are the grinding carbide wheels?
Diamond grinding wheel, carborundum wheel and so on.The diamond wheel: the diamond abrasive were used as raw materials, metal powder, resin powder, ceramic and metal plating as binder, made of the central circular hole is called consolidation abrasive diamond wheel (alloy wheel).
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:Hard alloy drill, stainless steel.
Normally, carbide drills are used without the central hole;Center hole as you said the drill is easy to collapse; (the center hole you were a little deep);Even if you hit a center hole, the effect is the location of the mark hole; so don't go too far.
Q:Where can I use cemented carbide?
The main application of carbide cutting tools, cutting tools and metal processing in geological drilling, drill and tool in shield construction. Manufacturing cutting tools, cutting tools, cobalt and wear-resistant parts, widely used in military, aerospace, aviation, machinery processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields.
Q:How to solve the severe wear of the flank of the carbide blade during machining?
2. Contact the company or log on to the company's website for communication.Carbide inserts are made of hard alloy, an alloy made from refractory metals, hard compounds, and bonded metals by powder metallurgy.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:Is hard alloy magnetic?
I use a magnet to suck the used MITSUBISHI VI15TF block and have some magnetism
Q:What's the difference between high speed tool steel and carbide cutter?
However, hard alloy is more expensive and it is too hard, and it is also a problem for its own processing, which makes it difficult to make tools with more complicated shapes, such as twist drills, by hard alloy
Q:Can CBN wheels grind cemented carbide? Why?
Cubic boron nitride grinding should not hard alloy and non-metallic hard materials in grinding, high temperature, CBN in alkaline aqueous solution will produce a chemical reaction, CBN wheel can be decomposed in 300 DEG C in alkaline solution, can trace decomposition in boiling water, the crystal grains were damaged, so the grinding, can only use oily the cooling liquid, and can not use water-based coolant.CBN wheel grinding for mild steel, heat-resistant steel, high hardness alloy steel precision grinding and finish grinding. The special steel products such as tungsten, molybdenum and cobalt high speed steel, alloy steel, high-speed steel with special grinding, super finishing machining of heat-resistant parts, and other steel quenching workpiece grinding line.
Q:Carbide blade domestic that tricky point?
Chengdu, Dalian Fuji, Chengdu Sentai eng, Qianmu NC tool and so on quantity.
Q:What does carbide wet grinding mean?
2. the number of grinding bodiesThe number of grinding bodies is usually described by the fill factor. The filling factor is equal to the ratio of the volume of the grinding ball to the volume of the cartridge.It is generally believed that the ball mill with carbide ball and carbide lining can guarantee the minimum coefficient of filling of rolling grinding by 0.4. When the filling coefficient exceeds 0.5, the ball near the center of rotation is blocked by the ball because of the small radius of rotation, so it is in a relatively static state with the grinding cylinder and reduces the grinding efficiency. Moreover, with the increase of filling factor, the grinding efficiency decreases regularly
