Ferroalloy production methods: Ferroalloys varieties, silica-alumina-calcium alloy, raw material complex physical and chemical properties of the alloy elements extracted big difference. So the production methods used are different. Depending on the different metallurgical equipment, high-silicon aluminum calcium alloy, there are mainly blast furnace, electric furnace, furnace extrajudicial, vacuum method and BOF blowing method. Ferroalloy production process: No guarantee furnace, silica, calcium alloy prices, preventing 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.
