Ferroalloy production methods: the blast furnace process. Easy to restore elements of ferroalloy and low-grade iron alloy, due to the required reduction temperature is low, may be similar to when the blast furnace smelting, Jiangsu silicon barium calcium, the process of smelting iron. But required higher temperature than pig iron, coke so big. Meanwhile, the coke as fuel and reductant, alloy carburizing, Hebei silicon barium, calcium, can only produce high-carbon products. Preparations before Ovens: ferroalloy production process. First check equipment. Conductive systems, electrode suspension system, batching systems, silicon, calcium, barium, electrode lifting systems, electrode pressure release system, transportation system; to closed furnace also includes a closed system, Liaoning barium calcium silicon furnace gas purification system, according to the production conditions for test , only after passing the oven.
