Product Description:


The BEST price & quality for various Ferro Silicon : 75%, 72%, 70%, 65%, 60%, etc.


Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.  

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

Q:I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!
Therefore, the processing of cemented carbide selection of the correct cutting fluid can produce good results, the general cutting fluid is not good, the quality of processing is very poor.
Q:Carbide and carbon steel
Carbon steel is a relatively traditional black metal material, according to the carbon content, nature, use, there are many categories. Carbon steels contain almost no alloying elements (except trace elements such as silicon, sulfur, phosphorus, etc.) during smelting. Carbon steel can be used for many daily purposes.Cemented carbide is a relatively new powder metallurgy material developed in recent years. The finish of the cemented carbide products is very high, even higher than that of ordinary quenched steel. Therefore, a machining tool that is often used as ferrous metal.
Q:Does the hard alloy belong to the composite material?
Grain refinement can improve both the hardness and toughness of the material. Hard alloys and cermets belong to particle reinforced composites, which change the size of hard phase and have great influence on the properties. In this paper, the preparation process of cemented carbide and cermet raw powder with different thickness is optimized, and two sets of materials with the same original chemical composition and different grain size are prepared by vacuum sintering technology.This is not how I suggest you go to Baidu search Suzhou haokai metal material limited company to ask it!
Q:Can hard alloy be made into barrel?
No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.
Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?
Hello, there is no way to avoid the problem of reducing the service life of the carbide coated drill bit after grinding;Cemented carbide bit, in its use, the surface coating, the blade has already been damaged, can not reach the integrity of the factory, so that it affects the service life of the drill bit,There is a need to be re grinding, coating, the coating has physical and chemical coating and coating, coating chemical now use more chemical coating basically is the tool coating at high temperature, so the temperature can cause 2 damage of cemented carbide substrate;So it also affects the service life;The effect of bit life, the most important is the geometric design of drill bit; before the design is not good, but when re grinding and grinding a good point, sometimes improve the service life, but the original drill must use will reduce the life of the;About those problems mentioned above, in fact, that is, some methods to improve the service life of the drill, upstairs can refer to
Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?
Basically the same, such as plastic wear, flank wear, crater wear, chipping... And so on, each kind of wear phenomenon has the reason, also has some remedial or the improvement measure....High speed steel has lower hardness and abrasion resistance ability is not high, but good toughness, high precision of complex cutting tools, such as broach, gear cutter or the use of high speed steel more, while the standard NC tool are used in a lot of hard alloy or indexable tool..
Q:Hard alloy bars where the hard alloy blade,
Hello, I'm from Zhuzhou CREE cemented carbide Co., Ltd.We are specializing in the production of various specifications of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy, sand making machine alloy strip, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin; manufacturers selling cheaper price; all kinds of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy sand making machine alloy, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin, everything, quality assurance; welcome you to come to the consultation, to serve you is our honor.
Q:What cemented carbide does 2gr13 use?
2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.
Q:What are the well-known brands of cemented carbide materials at home and abroad?
Domestic mainly Zhuzhou, the other side, the 601 factory is the best made in Zhuzhou. That is, the Taiwan side of the spring insurance is equal to the domestic better, and even better point is the German Lu Sheng Fort I know these, ha ha!
Q:Buy whole cold carbide drills
We are an internal cold carbide drill production professional manufacturers, imported materials, five axis processing.
