2.improve the intensity of the steel
3.widely used in steel industry
4.pure,efficie

       FeSi  is used as a source of silicon to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel; ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose. It can be used to make other ferroalloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.

FACTORY:


Q:What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.
Q:What does "YC20.1 carbide" brand mean?
PriceFor example, the ordinary 20 party 90 degrees welding tool used A320 blade, the price of 11 yuan, non tax written price /20120716 Edition
Q:How are hard alloy fittings machined and polished?
The fittings are then polished with a vibrating grinder!
Q:Carbide and carbon steel
Cemented carbides are of high hardness, but they are brittle. The toughness of high carbon steel is better.
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:High end markets for cemented carbides
In 2007, 16 thousand and 500 tons of cemented carbide produced in our country, 4500 tons were used in cutting tool production, and the quantity was quite similar to that in japan. But the value of the tool is only 800 million U. S. dollars, far less than Japan's 2 billion 500 million U. S. dollars, which fully shows that the overall production level of domestic carbide efficient tool is still quite a gap with foreign countries. Therefore, in the domestic enterprises can not meet the market demand under the premise of the manufacturing industry will have to rely on a large number of imports to solve. Data show that the main foreign market in China's high-end cutter sales growth rate of 30%, has exceeded the average annual growth rate of domestic knives.
Q:Model of grinding carbide wheel sheet
I. model:Generally, diamond grinding wheels are used for grinding carbide, and diamond grinding wheels are usually divided into diamond size. Model 400 is fine.Two. Brief introduction of grinding wheel:Also called consolidation abrasives, grinding wheels are bonded by the bond of ordinary Abrasives into a certain shape (most round, central through hole), and has a certain strength of the consolidation of abrasives. It is generally made up of abrasives, binders and pores. These three parts are often called the three elements of the bonded abrasives. In accordance with the different classification of binders, there are common ceramic (bond) grinding wheel, resin (bond) grinding wheel, rubber (bond) grinding wheel. The grinding wheel is one of the largest amount of abrasives, widely used, when using high-speed rotation can be cylindrical, metal or nonmetal workpiece inner circle, plane and various surface of rough grinding, semi fine grinding and fine grinding and notching and cutting etc..
Q:Carbide saw blades, plain and alternating teeth. What do you mean? That good?
.1., about the most widely used teeth, cutting speed, grinding relatively simple. Suitable for cutting and crosscut various soft and hard wood materials and MDF, plywood, particleboard etc.. Equipped with anti elastic protection around the tooth is tooth plate for dovetail, longitudinal cutting of various degree; with negative rake angle of tooth saw blade sharp, serrated cutting because of good quality, usually used for veneer cutting.2. flat tooth saw is rough, cutting speed is slow, grinding is the most simple. Mainly used for sawing ordinary wood, the cost is lower, more used for smaller diameter aluminum saw blade, in order to maintain cutting to reduce adhesion, or used for grooving saw blade, to keep the groove bottom leveling.
Q:What blade does the high carbide material use?
CBN diamond tools, the price is relatively high, high hardness with this basic file, but not the car more than 55 degrees of hardening, if necessary diamond tools contact me. Domestic imports.
Q:How to distinguish the authenticity of Zhuzhou diamond brand cemented carbide blade?
In fact, now only look at the packaging has been unable to identify, because now the copycat alloy packaging has really not with what two things, want to know after the authenticity can be used, you can try to buy a small amount of alloy, the quality of clearance to buy a lot, you can go to the station to find the Alibaba China @ Rui Sen # trade. Easy% Co., reputation has been good, but sales of hard alloy Zhuzhou diamond factory, there are quality problems can return shipping.
