Ferro Silicon

FeSi

Description

Ferrosilicon is produced by reduction of silica or sand with coke in presence of scrap iron, millscale, or other source of iron.

Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.

An overabundance of silica is used to prevent formation of silicon carbide. Microsilica is a useful byproduct.

The melting point and density of ferrosilicon depends on its silicon content.

Si content (wt.%)	0	20	35	50	60
Melting point (°C)	1538	1210	1410	1210	1230
Density (g/cm³	7.87	6.76	5.65	5.1	4.27

High Quality Inoculant FeSi Alloy

Q: Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy: Ha ha, I'm good at that!HC is the sign of the attractive magnetic force of the alloy, and HRA is the sign of hardness. COM is the cobalt magnetic mark of the alloy. D is the density of the alloy. The general quality certificate of the alloy product will have three indexes above

Q: CNC alloy milling cutter how to produce?What is the cutting edge of the machine tool?What is the surface coating?What is the cost of plating?Prawns talk about it in detail, I do alloy accessories, I would like to learn some processing methods ~ ~!: 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: Chengdu which has carbide scrap acquisition point?: Bars of 75000 yuan / kg (Fu Xujian) Zhejiang Zhoushan self-employed waste tungsten 150-200 yuan / kg, Hebei Hengshui Gucheng County Sindh rare metals tungsten tailings 100-300 yuan / ton Guangzhou lechran gold bars 1200 yuan / kg, Zhengzhou Zhengzhou Hongsen tin small PCB tungsten steel drill 160-190 yuan / kg in Zhejiang Taizhou

Q: What is hard alloy grinding?: Its scope of application and the artificial diamond plays a complementary role. Cubic boron nitride wheel grinding of steel parts the efficiency ratio of corundum wheel to nearly a hundred times, five times higher than the diamond grinding wheel, but less than the diamond grinding of brittle materials.The diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard processing material

Q: What kinds of carbides are there? How should we choose in production?: Basically divided into four major categories: YG, YW, YS, YT.YG is cast iron, nonferrous metal, base alloy steel.YW is made of stainless steel and base alloy steel.YS is the finishing of high strength steel, steel and cast steel.YT is the rough processing of steel and cast steel.

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: 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: The use of wire cutting cut a knife head rest wear found with magnetic iron absorption, cutting.: No, cemented carbide is mostly used as a knife head and has never seen a turning tool. It can also absorb ironBecause this is caused by friction, when the metal friction, so that the movement of free electrons become regular, resulting in a magnetic. If you want to remove the magnetism, you must make the motion of the free electrons irregular. For example, force, heat, etc.

Q: Import all carbide drill bit, mainly those brands: Good (maford), Kenna, Thomas, di tex, Sandvik, guhring general in the domestic production, the performance of discount.Now on the market is generally a bit alloy steel material whole bit, although the materials are the same, but due to the processing technology, various brands of product quality disparity. Imported and domestic alloy drills are also very different.Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m) in the application of high performance drill and ordinary milling machine, the hardness and toughness of the ideal together.Take high quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35, thermal stability up to 1100 degrees celsius. After coating, the drill color is bluish gray.After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.

Q: What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?: Cemented carbides are classified into 3 categories, and the ISO standards are defined as K, P, and m three. Each corresponds to the YG class, the YT class, and the YW class in our country. The material properties of P30 correspond roughly to the performance of our brand YT5. Suitable for carbon and alloy steels. But it is not suitable for machining titanium alloy or brittle material, because this kind of cemented carbide with high hardness, good wear resistance, but the strength is not enough, cutting the material easily.
