therefore also called interstitial (or insert) compound.

Mainly for the production of tungsten carbide material bowl. Tungsten eletrode carbide, the carbon atoms in the metal lattice embedded tungsten gap, does not destroy the original metal lattice, forming an interstitial solid solution, therefore also called interstitial (or insert) compound. Of tungsten carbide and carbon can be heated to high temperatures to obtain a mixture, the presence of hydrogen and hydrocarbons can accelerate the reaction. If the oxygen-containing tungsten compound prepared, the final product must be 1500 ℃ vacuum treatment to remove oxides of carbon. Tungsten carbide suitable for machining at high temperatures, can produce cutting tools, materials of construction furnace, jet engine, gas turbine nozzles.

Tungsten metal and carbon black as raw materials bowl, mix dubbed by a certain percentage, the mixed material was charged into the graphite boat, placed in carbon tube furnace or a sense of high frequency electric furnace at a temperature carbonization, and then after milling, screening that was carbide powder.

Born specializing in the production of tungsten carbide, chromium steel, manganese steel, mortar, feed bowl, disc, sample mill, vibration mill, crusher, drum machine, muffle furnace, oven, etc. are widely used in mining, coal, metallurgy, iron and steel, ceramics, X-ray fluorescence analysis and other departments and laboratories
