calcium carbide is a grey salt of calcium (CaC) used in making acetylene。

Application：

1、 Calcium carbide to generate acetylene after reaction with water to the synthesis of many organic compounds

2、 Heating powdered calcium carbide react with nitrogen gas, to generate calcium cyanamide, namely lime nitrogen, heating lime nitrogen and salt of black cyanide for gold mining and non-ferrous metal industry

3、 Calcium carbide itself can be used in iron and steel industry of desulfurizer

4、 Under the old miners ore, the calcium carbide will be use to generate in the tin can weave the calcium carbide acetylene (C2H2) into a lamp

Q: I only know a few big, like Zhuzhou, Chun Bao, Xiamen tungsten diamond. Anything else? I'm looking for a tool cutter: And Zigong cemented carbide, ah, the second largest domestic Oh. Tool can find me, ha ha.

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: Chengdu which has carbide scrap acquisition point?: What alloy do you have? A lot of home cash recycling, big price worries, good faith cooperation! This site in Jinniu District this way

Q: Can hard alloy be made into barrel?: No, hard alloy too hard too fragile, not processed, there should be a rifle barrel, it is difficult to machining.

Q: What are the common kinds of cemented carbides?: The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as YW1. (2) grade, composition, performance and application of commonly used hard alloy (see table below) categories of chemical composition of W/% grade performance scope of tungsten cobalt alloy YG3X 96.5 - < 0.53 for cast iron, nonferrous metals and alloy fine boring, fine car, can also be used for fine machining of alloy steel, Quenched steel and tungsten and molybdenum materials; high tungsten carbide content, binder content is low, its high hardness, flexural strength is low; therefore, YG3 is suitable for finishing; whereas the YG15 can bear larger load, suitable for roughing. Suitable for cast iron, nonferrous metals and alloys and non metallic materials roughing during continuous cutting, interrupted cutting of the semi refined car, fine car for percussive rotary drilling machine drilling hard rock, containing coal cutter teeth, hard rock drill, well drilling hard rock percussion drill bit, stamping die, planer and knife for percussive rotary drilling machine and other chisel hard and extremely hard rock, in the epidermis processing great work under stress perforation and stamping tools tungsten titanium cobalt alloy YT5 855 - 10 for carbon steel, alloy steel, forging, stamping, casting, uneven section, rough turning, discontinuous cutting the rough plane semi finishing.

Q: What is the difference between hard alloy steel and high speed steel?: 5, the scope of application is not the same: the general tool materials used carbide, complex difficult to shape, or require very sharp, high toughness and other field applicable high-speed steel

Q: Can carbide drills be used for high speed steel twist drills?: General workpieces do not need alloy drills, although durable, but the cost is too high

Q: Import all carbide drill bit, mainly those brands: Good (maford), Kenna, Thomas, di tex, Sandvik, guhring general in the domestic production, the performance of discount.Now on the market is generally a bit alloy steel material whole bit, although the materials are the same, but due to the processing technology, various brands of product quality disparity. Imported and domestic alloy drills are also very different.Imported alloy bit usually adopts VHM micro grain hard alloy (ISO K40), the type of ultrafine particles (0.6 m) in the application of high performance drill and ordinary milling machine, the hardness and toughness of the ideal together.Take high quality alloy bit surface coating, such as chromium aluminum nitride (AlCrN) coating, the coating layer of coating, the thickness of 4 m, the micro hardness is up to 3200HV, the friction coefficient of 0.35, thermal stability up to 1100 degrees celsius. After coating, the drill color is bluish gray.After coating, the alloy drill can process low alloy steel and high strength steel. High steel can reach 54HRC.

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.

Q: What does "YC20.1 carbide" brand mean?: PriceFor example, the ordinary 20 party 90 degrees welding tool used A320 blade, the price of 11 yuan, non tax written price /20120716 Edition
