FERRO TUNGSTEN

Ferro tungsten used as adding agent for tungsten element in steelmaking and casting, tungsten is one of the most important alloy elements in production of special steel. Tungsten can improve the strength and toughness of steel, but also improve the hardness and wear resistance of the steel while almost no reduce the elongation of the steel. In addition, another particular importance is that tungsten has good effect to improve the high temperature mechanical properties of steel, it can improve the heat resistance and tempering stability. The most common method of producte ferro tungsten is "plot block method", namely to reduction the oxide in tungsten concentrates in the electric furnace carbon , and then removed from the solidified metal product blocks from the furnace. Other methods are digging iron method and aluminotheric method. Ferro tungsten is a statutory inspection of goods... Ferro tungsten is alloy of tungsten and ferro, using to to increase the abrasion resistance power,..
