Q: hard alloy ball tooth, sand making machine, high quality and inexpensive alloy (*^__^*)I am now in great demand of cemented carbide rods, hard alloy blade, hard alloy ball tooth, sand making machine alloy strip, the old customers are not do, now I want to find a long-term cooperation partners, we have not recommended ~ ~ ~ thank you pull: Hello, I'm from Zhuzhou CREE cemented carbide Co., Ltd.We are specializing in the production of various specifications of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy, sand making machine alloy strip, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin; manufacturers selling cheaper price; all kinds of hard alloy, Zhuzhou cemented carbide, Zhuzhou hard alloy sand making machine alloy, hard alloy ball tooth, carbide blade, hard alloy bars, welding blade, milling cutter, long and thin, everything, quality assurance; welcome you to come to the consultation, to serve you is our honor.

Q: Hard alloy is tungsten?: You can understand that.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Cemented carbides include:Tungsten cobalt carbideThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).

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: Use of waste cemented carbide: Two, crushing methodFor hard alloy containing drilling is not high, because the hardness is relatively low, can use manual or mechanical means broken to a certain fineness in wet grinding mill for a period of time, to reach a certain size for reproduction of hard alloy. This force is a method has the advantages of simple process, short process, low energy consumption, no pollution to the environment, but often in the manual crushing hard alloy, metallic materials due to debris into the tools have broken material pollution, in addition, due to the hard alloy drill containing high amount of easily broken, mechanical crushing method is very limited; cemented carbide complex material by this method is also very difficult to ensure the quality of recycled products. Process method: artificial crushing is broken, crushed into powder 200 mesh or using bulk of hard alloy ball mill for crushing strikes the ball, then add in the bjm alcohol in wet grinding, and then enter the remanufacturing process of hard alloy.Some companies use cooling method: first crushing waste hard alloy in a muffle furnace heated to 80 above this immediately into the water quench, resulting in hard alloy cracking, and then enter the mechanical crushing process. This force is a method in the last century in 90s in Hebei Province Qinghe to gain popularity, there were dozens of county size ranging from recycling plant using the recycled and processed hard alloy, hard alloy processed over a thousand tons of annual production, the total output value of 300 million yuan, becoming one of the local pillar industry. At present, there is still a certain space for development of the crushing method, and the crushing method still needs to be improved by adopting more advanced and clean crushing equipment or by means of the force method which does not destroy the microstructure of cemented carbide with high efficiency.

Q: What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: YW refers to the national standard brand. YS30 and YN10 are made by the company themselves. The brand is made up of the largest cemented carbide producer in China, Zhuzhou 601 (Zhuzhou cemented carbide group).

Q: What does American standard cemented carbide grain size C mean?: Then, when the mixture is granulated and pressed and heated to a point near the bonding metal (1300~1500 DEG C), the eutectic alloy is formed by the hardening and bonding of the metal. After cooling, the hardened phases are distributed in a grid of bonded metals that are closely related to each other and form a solid whole. The hardness of cemented carbide depends on the content of the hardened phase and grain size. The higher the content of the hardened phase and the finer the grain, the greater the hardness. The toughness of cemented carbide is determined by bonding metal. The higher the bonding metal content is, the greater the bending strength is. The effect of grain size on the mechanical properties of metals has a curve diagram: the strength of both ends is large and the middle is low. Explain: the mechanical properties of single crystals are very good. The finer the grain, the better the mechanical properties, but the mechanical properties of the single crystal with infinite size are much better than the grain's infinitesimal! A lot of grain size control method, the main principle of two: 1, increase the metal crystallization undercooling of 2, increase the crystal nucleus specific methods: electromagnetic stirring, adding grain refiner (such as Aluminum Alloy plus Al-Ti-C master alloy as grain refiner), lower solidification temperature, and fine grain of alloy elements and so on many.

Q: What are the fields of nano WC Cemented Carbides applied?: (2) electronic industry. The development trend of electronic products is miniaturization, integration and precision. The integrated circuit board is made of epoxy resin, glass fiber or glass fiber reinforced plastic. This requires micro drill has high hardness and wear resistance; while the drill diameter is very small (generally 0.2 ~ 0.3mm, and 0.05mm), easy to break, also called bit has high strength and toughness, and need to correct drilling hole position accuracy, and the drill bit has high stiffness (elastic modulus). These conflicting requirements. The common hard alloy and fine grain carbide drills are difficult to meet these requirements, only the use of nano grain carbide grain size of less than 0.5 m. And as the dot printing needle, its diameter is only 0.2-0.35mm; multi frame processing integrated circuit lead by the progressive die, punch thickness less than 0.2mm, the error is only 0.002mm; in addition to the printed circuit board with wire cutting head disc cutter, and the precision of the small die, all require the use of Nanocrystalline WC cemented carbide in order to achieve its function to produce alloy.

Q: The welding welding hard alloy cutter, should use what type of flame why: With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be

Q: What materials are hard alloys used to process?: YW hard alloy, high temperature resistant, wear-resistant, high hardness steel, stainless steel and so on.

Q: The difference between cemented carbide and tungsten.: The market is usually called tungsten carbide, the two are the same, and the high speed steel called high speed steel. This is the old habit of name of state owned enterprises.
