Specifications

Ferro Silicon 72% & 75%.It is used extensively in the steel-making, casting non-ferrous metals and other industrial production.I

1, Features:
The appearance of Ferro Silicon is the grey lumpish solid. It has very strong stabilities and does not place any chemical reaction in the dry air.

2, Application:
It is used extensively in the steel-making, casting non-ferrous metals and other industrial production.It is the good deoxidizer and most steel kind use the Ferro Silicon for deoxidization;

In steel smelting, it is used to sedimentary accretion and expanding deoxidizing.It is used to prove the strength, hardness and elasticity of steel greatly in steel casting.

FeSi 72%&75% With Chinese Origin Export

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: What is the difference between them?From hardness, abrasion resistance analysis!: Is the use of metal carbide hard alloy with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. Its hardness is 93 HRA8, high temperature resistance of 850 ~ 1000 C, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, hard alloy is commonly used tungsten cobalt (YG), tungsten titanium cobalt (YT) and general hard alloy (YW) three.Diamond is an allotrope of carbon, natural diamond and diamond two.

Q: What are the grinding carbide wheels?: Diamond grinding wheel, carborundum wheel and so on.Diamond grinding wheel is a diamond abrasive were used as raw materials, metal powder, resin powder, ceramic and metal plating as binder, made of the central circular hole is called consolidation abrasive diamond wheel (alloy wheel). Only welded blades use carborundum wheels, and generally fine grinding blades use diamond grinding wheels. The best tool is mounted on a tool grinder with a high speed. The tool is polished and has a good finish.

Q: Carbide die how to calculate weight, that is to say, its kg weight: The density of tungsten, cobalt and titanium carbide is 9.7~13.2, and the higher the content of titanium carbide, the lower the density.

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: I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?: The surface quality is good, the blank diameter is 50MM. Can play around eight hundred rpm. When the car is refined, 1200r/min.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.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.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron and non-ferrous metals.

Q: What type of emery grinding machine is 3000/min for grinding carbide turning tools (e.g., YG8.YS8.YT15.YW1, etc.)?: Diamond grinding wheel, green carborundum wheel can be used. Two, choose one, or choose the former good. Diamond grinding wheel has the advantages of less wear, long life, high productivity and good processing quality, that is, the price is a little more expensive.

Q: Carbide and carbon steel: Hard alloy knife, cutting knife, carbon steel is the food, so simple.

Q: What does "YC20.1 carbide" brand mean?: PaInstead of old products, YT15 YT14A new brand with a slightly higher price of 40%, which has not been done

Q: What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?: ISO (International Organization for Standardization) will be divided into carbide alloy P, M, K three categories, P class equivalent to China's YT class, the main ingredient is WC-TiC-Co;In order to be processed in different cutting conditions of material grade, in the P class with 01-50 number between that from the highest hardness to a series of alloys for maximum toughness between P30, roughly equivalent to the YT5 of our country;This kind of cemented carbide has the highest strength and best impact resistance in YT (P), but it has poor wear resistance. It is suitable for intermittent roughing of general carbon steel and alloy steel.
