Ferroalloy production technology trends: the use of advanced production technology. Continuous smelting calcium alloy, one-step metallurgical silicon chromium alloy, heat exchange method (Bohlen method) production of low-carbon ferromanganese and low carbon ferrochrome and other production processes, Tianjin calcium aluminosilicate particles, shorten the process, Si calcium particles, reduce energy consumption, improve production efficiency, thereby reducing the cost of production and consumption. The use of fine materials technology. Concentrate ferroalloy production technology is an important part of production and consumption reduction. Such as the use of high-quality combination of carbonaceous reductant, with gas coal and bituminous coal, instead of part of the metallurgical coke; sintered ore, pellets, iron ore pellets, iron pellets and other scales, Henan calcium aluminosilicate particles to improve the preparation techniques and conditions of the furnace ore into the furnace, thereby improving productivity. Ferroalloy production process: Ovens. Early Ovens electrodes and other equipment subjected to heat a small, Jiangsu calcium aluminosilicate particles, therefore, requires less cooling water, a small amount must be controlled depending on the heat, then the water must be unobstructed. Electrodes wind can not open, depending on the heat after, adjusting the amount of water and wind. In order to prevent oxidation of the bottom carbon brick, after all the preparatory work is completed, in the bottom layer of about 100mm coke powder (0 ~ 3mm), then be oven.
