                  FERRO SILICON

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:What are the types of cemented carbides?
5, industry special cutter category, including auto industry special knife, mobilization machine, industry special knife, sewing machine industry special knife, die industry special knife, textile machine special knife and printed circuit board industry special knife.Hard alloy tool with cemented carbide and carbon steel bar welded, it is characterized with high hardness, wear resistance and heat resistance of hard alloy blades are made of high abrasion resistance and high heat resistance WC (tungsten carbide), TiC (Tan Huatai), TaC (TAC) and Co (cobalt) powder after high temperature sintering.Different cemented carbide is suitable for different purposes, so you can refer to the following, I hope you can help!
Q:Which is better, cemented carbide, YG8 and YG20?
YG8 and YG20 are two grades of cemented carbide. They are not good or bad. It depends on what occasion you use
Q:Why carbide fracture?
Hard alloy is made by casting sintering of tungsten and cobalt, nickel, titanium and tungsten powder, cobalt and nickel matrix, and it is easy to break a bonding metal, quality and technology, process equipment, but also related to the amount of metal content and bonding, in short, hard alloy production is very complex, the quality is strictly, in order to produce good toughness, wear-resistant tungsten is a long-term process of exploration, experiment, a link may not have a good grasp of the products are not qualified.
Q:What type of carbide is the most ductile?
Cemented carbide material with tungsten and cobalt carbide toughness is better, at present the carbide grade in the most toughness of YG15. The relation between cobalt content and toughness is shown below. It can be seen that cobalt content and 13%-16% toughness are the best. In this interval, only YG15 cobalt content is 15%.
Q:What are the fields of nano WC Cemented Carbides applied?
(3) wood processing. As early as 50s, carbide tipped tools were used in the wood processing industry. Now, there sheet of all kinds of materials, the processing precision and the requirements of the appearance is greatly improved, the centrifugal force, when high speed cutting cutting force so that ordinary hard alloy is difficult to meet the requirements of the processing, and nanocrystalline WC cemented carbide has been useless.
Q:The wood cutting tools are made of hard alloy, high speed steel and diamond.
A total of 10 ~ 25%. Under the condition of heat generated in the high-speed cutting (about 500 C) can still maintain a high hardness of HRC can be more than 60. This is the main characteristic of high speed steel - red hardness. And carbon tool steel after quenching and low temperature tempering, at room temperature has very high hardness, But when the temperature is higher than 200 DEG C, the hardness decreased rapidly, at 500 DEG C hardness has been reduced to a similar degree with annealing state, completely lost the ability of metal cutting, which limits the production of carbon tool steel and high-speed steel cutting tools. The red hardness, make up for the fatal defect of steel with carbon. That can be used in the manufacture of cutting tools.
Q:How are carbide cutters made? 20
The price varies from a few thousand dollars to a few days depending on the size of the blade and the specificity.Surface coating is usually coated with titanium (such as titanium nitride, etc.)Large manufacturers such as diamond coating equipment general equipment in the tens of millions of yuan in cost is quite high, in Jiangsu there is a foreign company specialized in coating equipment sold to undertake external coating business, the coating cost with you a coated blade is related to the price from a few dollars to tens of dollars / piece / slice.
Q:YC45 carbide cutting tools 10
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 kinds of carbide knives do you have? Write out its main functions and uses.
(3) tungsten tantalum cobalt (WC+TaC+Co) cemented carbide (YA);The addition of TaC (NbC) on the basis of YG cemented carbide improves the hardness and strength, thermal shock resistance and wear resistance at room temperature, high temperature, and can be used to process Cast Iron and stainless steel.(4) tungsten, titanium, tantalum, cobalt (WC+TiC+TaC+Co) and hard alloy (YW), such as W1, W2 and so on.On the basis of YT cemented carbide, TaC (NbC) is added to improve the flexural strength, impact toughness, high temperature hardness, oxygen resistance and wear resistance. Both can process steel, but also the processing of cast iron and non-ferrous metals. Therefore, it is often called universal cemented carbide (also known as universal cemented carbide). At present, mainly used for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.
Q:Carbide yk20? What do you mean?
Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.
