Subsequently the oxide is reduced to tungsten metal in a hydrogen atmosphere. The metal powder is then mixed with carbon and carburised underinert atmosphere at high temperatures. The production parameters are decisive for the WC grain size in the sintered carbide.Powder preparationThe tungsten carbide is intensely mixed with the binder metalcobalt, nickel or iron, various grain growth inhibitors and materials,which promote compaction, by wet grinding so that ahomogeneous suspension is created. Afterwards, the suspensionis dried in a spray tower to produce a granulate with goodflow characteristics. This granulate represents the basis for allforming processes.metal formingThe objective of the forming process is to obtain a near netshape sample. Pressing is normally carried out at room temperaturewith pressures reaching up to several tons per squarecentimetre.There are several ways of pressing blanks:During isostatic cold pressing the powder is filled into an elasticflexible hose and pressed into a compacted form throughhigh liquid pressure. The powder blocks which are producedin this way can then be processed mechanically. All commonmachining methods like milling, cutting, drilling or turning maybe applied.In uniaxial pressing the pressing tool consists of a die and anupper and a lower punch. The carbide powder is filled into thedie and then compacted to create the so called green carbide,which is ejected from the pressing die.Extrusion pressing is mainly used to produce rectangular baror cylindrical rod, with or without axial hole(s). A plasticiser isadded to the powder. The resulting paste is pressed throughan extrusion nozzle. Before sintering, the plasticiser must beevaporated in special drying furnaces.metal Injection Moulding (MIM) is a process used to producemore complex forms which cannot be produced by directpressing. The paste preparation is similar to the extrusionprocess.Sintering processThe sintering process converts the blank into a homogeneousand dense carbide with a high level of hardness. The materialis sintered at temperatures between 1,300 and 1,500 °C(liquid phase sintering) and sometimes also at high pressure(up to 100 bar). The volume is reduced by up to 50 % duringthis process.FinishingIn order to achieve the final requirements of surface finish, tolerances,etc. carbide parts can be subjected to a series of finishingprocesses such as grinding, spark erosion and coating.Zhuzhou HuijinCemented carbideCo., Ltd is located in Zhuzhou City, Hunan Province, China, where is the largest tungsten carbide producing area in China.Our mainpr-oducts inclue: Tungsten carbide rods, carbide strips, carbide dies and bushes, tungsten carbide roll rings, carbide disc cutters, carbide end mill cutters, carbidestud and pins, tungsten water jet cutters, precision tools, tungsten carbide grits and powder, welding rods, ceramet inserts, PCD and CBN tools, non-standard and deep-processing products and so on.
