Sell Cast Tungsten Carbide

Description

Metal tungsten and tungsten carbide powders as raw materials are mixedï&frac*4;Œpacked in a graphite boat, melted in a melting furnace at about ***0℃ï&frac*4;Œand held for a certain time to obtain alloy casting block of cast tungsten carbide with phase diagram of W2C and WC and particle size of **3µm. Particle are silver grey with metal luster. Cast tungsten carbide is applied by oxygenace-tylene flame, arc, spray, braze and wet welding on wear ***** is also adhered firmly to the surface of wear work pieces with epcxy resin and inorganic additives at lower temperature and ***** parts of build-up cast tungsten carbide coating can stand with high temperature and ***** is characterized by long tool life, easy maintenance, low coat and improved productivity. In the production, whether equipment normally run is dependent on materials wear resistance for wear parts in great degree.Selection of materials with better wear resistance provides longer equipment-life and stable running. Cast tungsten carbide as a wear material is widely used in the mining, petroeum, construction and agricultural machinery and steel industry etc.because of its high hardness (HRA *3.0~*3.7), good wear resistance, easy build-up welding and low cost.
