Calcium and silicon and oxygen has a strong affinity.Especially calcium, not only with strong affinity, oxygen and sulfur, nitrogen has a strong affinity.So the calcium silicon alloy is a kind of ideal compound deoxidizer, desulfurization agent.Silicon alloy not only deoxidization ability strong, deoxidizing products tend to rise, easy to discharge, but also can improve the performance of the steel, plasticity, impact toughness of steel and liquidity.Currently the calcium silicon alloy can be final deoxidization instead of aluminium.Be applied to the high quality steel.In the production of special steel and special alloys.Such as rail steel, mild steel, stainless steel, steel and nickel base alloy, titanium alloy, and other special alloy are available the calcium silicon alloy as deoxidizer.The calcium silicon alloy also for practice of converter steel workshop with increasing agent, the calcium silicon alloy can also be used for cast iron inoculant and additives in nodular iron production.
Binary alloys of silicon and calcium, belongs to the category of ferroalloys.Its main ingredients for silicon and calcium, but also contain different amounts of iron, aluminum, carbon, sulfur and phosphorus and other impurities.Iron and steel industry as a calcium additive, deoxidizer, desulfurization agent and nonmetal inclusions denaturant.Used as a nucleating agent and denaturant cast iron industry.The calcium silicon alloy by calcium and silicon content of different is divided into:
| Ca（>） | Si | |
Ca31Si60 | 31 | 50~65 |
| Ca28Si60 | 28 | 50~65 |
| Ca24Si60 | 24 | 55~65 |
| Ca20Si55 | 20 | 50~60 |
| Ca16Si55 | 16 | 50~60 |
- Q:What kind of carbide alloy is used in stainless steel processing?
- Machine tool steel. Better cooling, liquid viscosity and sulfur chosen for good cooling performance, the pressure of the cooling liquid chlorine.
- Q:How to distinguish cemented carbide grades?
- (3) titanium cobalt tungsten tantalum carbide (WC+TiC+TaC+Co)) (YW YS) "the main processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing" in addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, wear-resistant and anti oxygen ability. Can be processed and can be made of steel, cast iron and non-ferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy). The following is a variety of grades, density, bending strength, hardness and flexural strength hardness grade use density of use of YG3X 14.6-15.2 132092 is suitable for cast iron, nonferrous metals and alloy steel small alloy steel cutting section of high-speed machining. K01 YG3X YG6A 14.6-15.0 137091.5 for hard cast iron, non-ferrous metalsalloys, also suitable for high manganese steel, hardened steel, alloy steel and semi finishing K05 YG6A YG6X 14.6-15.0 finishing. 142091 it is proved that the alloy processing of chilled alloy cast iron and alloy steel can obtain good results, finishing is suitable for ordinary iron. K10 YG6X YK15 14.2-14.6 210091 for the whole processing of drilling, milling, reaming and alloy cutter. Have high wear resistance and toughness of K15. K20 YK15 YG6 14.5-14.9 138089 is suitable for cast iron, nonferrous metals and alloy non metallic materials at medium cutting speed precision.

- Q:What kinds of carbide knives do you have? Write out its main functions and uses.
- (2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.
- 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:Printing requirements for cemented carbide
- Because of its superior properties such as high strength, hardness, excellent wear resistance and oxidation resistance, carbide is widely used in mechanical processing, petroleum mining, mold forming and structural wear-resistant parts and other fields. In the production of cemented carbide, sintering is the most important process. Even if the compacts are the same, different sintering processes have different effects on the properties of the sintered products. For a long time, many researchers have gradually formed a variety of sintering methods in actual production, including vacuum sintering, hot isostatic pressing sintering, vacuum follow-up hot isostatic pressing, sintering, hot isostatic pressing, etc..
- Q:Carbide grades, properties and applicable ranges
- (4) tungsten titanium tantalum cobalt (WC+TiC+TaC+Co) cemented carbide (YW);In addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, anti oxygen ability and wear resistance. Both can be processed and can be made of steel, cast iron and nonferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy) mainly. For the processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing.
- 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:Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy
- Ha ha, I'm good at that!HC is the sign of the attractive magnetic force of the alloy, and HRA is the sign of hardness. COM is the cobalt magnetic mark of the alloy. D is the density of the alloy. The general quality certificate of the alloy product will have three indexes above
- Q:YW2 carbide blade type
- As far as I know, the blade is distinguished by code, not by outside. YG is a precision blade, but it is free of impact, and the amount of feed can not be too large. YT this is a rough turning tool, especially a good iron. That's all.
- Q:What is the hardness of YG8 cemented carbide?
- The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.
