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:What are the three types of commonly used cemented carbides?: As the mass fraction of cobalt increases, the hardness and wear resistance decrease, and the flexural strength and toughness increase.M class (equivalent to our YW class), cemented carbide is based on WC, TiC, Co, and then added TaC (or NbC). After the addition of TaC (or NbC), the comprehensive properties of cemented carbide were improved. This kind of cemented carbide can process both cast iron and non-ferrous metals, and also can process steel materials. It can also process difficult materials such as high temperature alloy and stainless steel. Commonly used brands are YW1 and YW2.

Q:Hard alloy die polishing with what can be reached Ukraine black brightness: What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder

Q:Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?: Friends, according to your question, if change my words, I choose YS25Grade ISO grouping, code name, density, bending strength, hardness, useYS25 12.8 P25 13.2 = 1780 = 90.5 for carbon steel, cast steel, high manganese steel, high strengthRough turning, milling and planing of steel and alloy steelYou mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies

Q:Will the alloy produced at 400 watts be decarburization or carburizing?: This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.

Q:Compare the advantages and disadvantages of high speed steel and cemented carbide: Must be in a hardened state, in high speed steel iron, chromium, tungsten and carbon forming hard carbide can improve the wear resistance of steel (hardness of HRC6468). Another part of tungsten dissolved in the matrix, increase the hardness of steel red.High speed steel can reach 650 degrees of red hardnessHigh speed steel has good strength and toughness, cutting edge is sharp after grinding, and its quality is stable. It is used to make small and complex cutting tools

Q:What is called cemented carbide?: 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 are widely used as tool materials. 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. Hundreds of times now cutting speed of new carbide tool is carbon steel.Carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasives, cylinder liner, precision bearings, nozzles and so onIn the past twenty years, coated carbide also come out in Sweden.1969 in the successful development of titanium carbide coated tools, the tool is a matrix of tungsten carbide titanium carbide cobalt alloy or cobalt tungsten carbide, titanium carbide surface coating thickness of only a few microns, but with the same grade alloy tool compared to prolong the service life of 3 times, cutting to increase the speed of 25% ~ 50%.20 in 70s has been fourth generation coating tools, can be used for cutting hard processing materials.

Q:Material properties of Cemented Carbides: Hard alloy with high hardness of refractory metal carbides (WC, TiC) micron powder as the main ingredient, with cobalt or nickel (Co) (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction sintering furnace. IV, B, V, B, VI, B group of metal carbides, nitrides, boride, etc., because of hardness and melting point is particularly high, collectively referred to as cemented carbide. The structure, characteristics and application of hard gold content are described with carbide as the key point. IV, B, V, B, VI, B group metals and carbon formed in the metal type carbide, because the carbon atom radius is small, can be filled in the gaps of the metal lattice, and retain the original lattice form of metal, forming interstitial solid solution. Under appropriate conditions, such solid solution can continue to dissolve its constituent elements until it reaches saturation. Therefore, their composition can change in a certain range (such as the composition of titanium carbide in TiC0.5 ~ TiC changes), chemical formula does not conform to the rules of valence. When the dissolved carbon content exceeds a certain limit (such as titanium carbide in Ti: C=1: 1), the lattice type will be changed, the original metal lattice metal lattice into another form, then the interstitial solid solution called interstitial compounds.

Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?: There are two reasons1. The tool itself quality problems of our factory has been recommended 3-turn Kuwait this brand2. Just the material, good hardness of material, speed, feed, reduce the point properly, can protect the tool wear well

Q:How hard metal is welded with stainless steel?: Braze welding can be used.Carbide containing tungsten, vanadium and other metals, melting point higher than stainless steel, can be considered

Q:Classification of Cemented Carbides: Baidu Encyclopedia of hard alloy introduced very clearly
