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.

1.Ferro silicon is often used as deoxidizer in steel making.

Q: What brand of carbide is used in woodworking tools?: Carbide YS2T: is used for low speed roughing and milling of heat resistant alloys and semi finishing of titanium alloys, stainless steels, and low alloy steels. Carbide YL10.2: has high flexural strength and good wear resistance, used in low speed rough car and milling heat-resistant alloy, titanium alloy, also can be processed glass fiber reinforced plastic, making PCB micro drilling and so on. YG3/YG6: is suitable for hard alloy cast iron, nonferrous metals and their alloys and non metallic materials during continuous cutting fine cars, semi refined car, suitable for small section iron fine car, and can be used for the coarse thread, steel, nonferrous metals, wet lubrication tensile alloy wire and non metal wire drilling etc..

Q: Why is carbide cutting tools less standard than high speed steel cutting tools?: Because carbide cutting tools wear better than high speed steel cutting tools.

Q: Carbide grades, properties and applicable ranges: The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co which has higher flexural strength, toughness, good thermal conductivity, but heat resistance and poor wear resistance, mainly used for processing cast iron and nonferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, the hardness, wear resistance than YG3 YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.

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

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: Is nickel base alloy hard alloy?: There are three kinds of cemented carbides used in machining,:1, YG--- tungsten cobalt alloy products, the YG6 is generally suitable for machining cast iron, roughing non-ferrous metals and their alloys and non metallic material during continuous cutting, interrupted cutting of semi fine fine cars and trucks etc..

Q: What is the heat treatment process of cemented carbide?: The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.

Q: What about cemented carbide produced in Zhuzhou? What brand is good?: Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.

Q: I want to process more hard stainless steel, with YC45 this type of carbide knife can do? Where can I buy authentic, know the friend told me, thank you: Not suitable. YC45 is used for rough machining of general steel.If you have a low nickel content in your stainless steel, it is more suitable to use YD101 after hardening. If the nickel is high and the material is highly ductile, use the YBM series.Domestic hard alloy Zhuzhou diamond is better, you find a formal agent in Zhuzhou near you to buy.

Q: What are the differences in performance between cemented carbide cutting tools and PCD cutters (polycrystalline diamond)?: The former is cut by ordinary metal materials, the latter is used for cutting superhard materials
