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 is called cemented carbide?
- In addition to carbon atoms, a nitrogen atom and void boron atoms can enter the metal lattice, formed interstitial solid solution. With the properties of mesenchymal type carbide. They are similar to electrical and thermal conductivity, high melting point, high hardness, brittleness and is also large.The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is bonded metalIs the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 degrees. In addition, nitrides, borides, silicides of transition metals have similar characteristics, can also act as a hardening in hard alloy the phase hardening phase due to the existence of alloy with high hardness and wear resistance.Bonding metals are generally iron based metals, and cobalt and nickel are commonly usedManufacture of hard alloy, the size of raw powder in 1 ~ 2 microns, and high purity. Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class then, after drying and sieving to prepare a mixture. Then, the mixture granulation, pressure type, heated to the melting point of the metal bond (1300 to 1500 DEG C) when hardening phase and bonding metal to form eutectic alloy. After cooling, the hardening phase distribution in grid bonded metal composition in each other closely together, form a firm whole. The hardness of the hard alloy depends on the hardening phase content and grain size, the hardening phase content is higher, more fine grain, hardness is greater. The toughness of cemented carbide by bonding metal bonded gold decision. The higher the content, the greater the flexural strength
- Q: What's the use of recycling cemented carbide?
- In the cutting tool is also hard alloy materials, recycling can be re - cemented carbide cutting tools ah.
- Q: Where can I buy more than 94 hardness carbide cutter head, welding, the best address in detail, thank you!
- It's no problem to weld cemented carbide. Please call me when you need it
- Q: What does WC refer to in cemented carbides?
- Tungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt.The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.For example, YT15, which represents average TiC=15%, is tungsten carbide cobalt carbide with the remainder of tungsten carbide and cobalt content.Tungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
- Q: The use of cemented carbides YG and YT
- Three, need to point out is: YG, YT, YW each alloy has different models, each model has different applicable range, the above refers to the comprehensive analysis.
- Q: Why is carbide cutting tools less standard than high speed steel cutting tools?
- Because the hard alloy material rigidity is better, the brittleness is bigger, the toughness is relatively bad, namely is easier than the high speed steel cutting tool to break off, after grinding blunt, the force is more complex. Greater resistance.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. 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.
- Q: What does carbide wet grinding mean?
- 2. the number of grinding bodiesThe number of grinding bodies is usually described by the fill factor. The filling factor is equal to the ratio of the volume of the grinding ball to the volume of the cartridge.It is generally believed that the ball mill with carbide ball and carbide lining can guarantee the minimum coefficient of filling of rolling grinding by 0.4. When the filling coefficient exceeds 0.5, the ball near the center of rotation is blocked by the ball because of the small radius of rotation, so it is in a relatively static state with the grinding cylinder and reduces the grinding efficiency. Moreover, with the increase of filling factor, the grinding efficiency decreases regularly
- Q: I am 985 material girls graduated, looking for a job, want to know about
- Prospects for the development of hard to say, look at individuals, we this profession, if it is small Shuo, the main income is project bonus, this with your personal ability is very large. These two enterprises are similar in terms of welfare benefits. If you're a girl, it's better to suggest a closer home. Jiangxi copper did not understand, ask your elder sister what, to see if there is no inside, we also find out from these companies in Shixiongshijie there, not just listen to HR talk.
- Q: What is the base material of carbide saw blade?
- Carbide saw blades include the kinds of alloy cutters, matrix materials, diameter, tooth number, thickness, tooth shape, angle, aperture and so on. These parameters determine the machining ability and cutting performance of saw blades. In selecting the saw blade, it is necessary to select the saw blade according to the kind, thickness, sawing speed, cutting direction, feeding speed and width of saw.
- Q: The difference between HSS and carbide knives
- High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.
