1.硅铁 依赖于炉料的质量,特别是用半焦和铸造焦代替焦粉和核桃焦时,单位电耗要提高7％左右。由于细粒石英(80～30mm)代替粗粒石英时,会促使炉喉表面附近料层的SiO_2气化,增加硅的损失和恶化其它生产指标,所以应使用适宜的石英粒度(120～80mm)。采取熔池高料位对更完全地回收硅有利。加入含钙添加物能保证按时出渣并改善炉喉工作,而且还能使随炉渣和炉气损失的硅减少3～5％;加入的方式,既可周期性地加入,也可配料时加入。在流水作业输送炉料的车间内,改变组份后的炉料要经过
1. Ferrosilicon depends on the quality of the charge, especially with semi-coke and foundry coke instead of coke and walnut coke, the unit power consumption should be increased by about 7%. Because fine quartz (80 ~ 30mm) instead of coarse quartz, will promote the throat near the surface layer of SiO_2 gasification, increase the loss of silicon and deterioration of other production targets, it should be the appropriate quartz particle size (120 ~ 80mm) . Taking the molten pool high level is beneficial to more complete recycling of silicon. Addition of calcium-containing additives ensures timely slag removal and improved throat work, but also reduces silicon loss by 3 to 5% from loss of slag and furnace gas; additions can be made either periodically or with ingredients .
