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

Q:Hard alloy and cast iron join together, use temperature 150 degrees, what glue is better to use?: Why use glue only? Recommend the use of welding, as welding tool is not the same as you can.

Q:Why is Zhuzhou cemented carbide plant called (601) what is this code number? What does it stand for? 601, production of military?I found the Zhuzhou code factories such as: Zhuzhou hard alloy factory (code 601) Zhuzhou Southern Power Machinery Factory (code 331) Zhuzhou vehicle factory (code 430) add code 6+0+1=7 3+3+1=7 4+3+0=7 are equal to 7 this is the 7 to have the meaning or coincidence: Chinese at the age of 60 or 70, due to the impact of the cold war, many industries are not afraid of war on the coast, Taiwan will take the industry to play, so they relocated to the mainland, as you said before the hard line called the 601, is a military plant, later not what the three line construction, and there are a lot of factory moved west, such as Sichuan Zigong Zigong Hard Alloy Co. Ltd., is the 601 part of the move in the past. The Zigong that 764. Not only is the hard alloy, ceramic, what other power machinery factory, before there is a code, is estimated at that time in order to strategic needs, Nanchang also has a Nanchang hard alloy factory, formerly known as the code that can be 603, and now the number plate of the car of a kind, a code.If you are in the 60 or 70's 601, most people do not know what is the 601 factory production which, what, if you like this that hard line, people knew it was Zhuzhou Cemented Carbide Production factory, I think it is to be kept confidential, let outsiders do not understand, a code to Kazakhstan a security role that theWell, please forgive me. I've been in 764 for over a year.

Q:Model of grinding carbide wheel sheet: Generally, diamond grinding wheels are used for grinding carbide, and diamond grinding wheels are usually divided into diamond size. Check the manual and choose it by roughness.

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 kinds of carbide cutting tools are used in the 16 and 20 manganese grinding of the lathe?: This material I have processed, it is equivalent to Q235 carbide tools, wear-resistant coarse cars, YW, fine car YT15YG: for cast ironYT: suitable for processing steel partsYW: the material performance of the tool is between YG and YTYN: it is a cermet blade suitable for machining superhard materials.Diamond: cutting tools are suitable for machining superhard materials, but they can not be processed steel or ironIn order to be compatible with them.CBN: Machining superhard materials.

Q:suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?: Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced

Q:Why carbide fracture?: First you have to choose the right material. Various uses must choose the relative grade, and also has the material which you use, has the sundry inside

Q:allowing the use of larger anterior angle, generally high speed steel tool than the hard alloy tool angle _______.A0 degrees ~5 degrees, B6 degrees, ~10 degrees, C11 degrees, ~15 degrees: Different rake rake angle and carbide cutting tools of high-speed steel cutting tools, but according to different materials, the front angle and cemented carbide cutting tools of high-speed steel cutting tool rake angle difference is different;

Q:What kinds of carbide knives do you have? Write out its main functions and uses.: (2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.

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
