Ferroalloy uses: yield, variety and quality ferroalloys directly influence the development of the steel industry in Hebei novel calcium, barium aluminosilicate, the amount usually accounts for about 2% to 3% of steel production. With the development of modern science and technology in Shandong new Si-Ba, calcium, iron alloy varieties is growing. Ferroalloy variety, classification and more. Ferroalloy production process: No guarantee barium calcium aluminosilicate new furnace, to prevent the electrodes and the bottom phase adhesion, should build a layer of clay beneath the electrodes (65mm) and light Soderberg electrode layer on the brick. In the bottom electrode diameter crushing shell loaded enough (block degree 50 ~ 100mm) of electrode paste, paste assurance column height of about 3500mm, to obtain a sintered good electrode.
