硅系列合金冶炼过程中,对入炉硅石不但有一定的粒度标准,而且对SiO_2、伴生氧化物的含量和矿石冶炼性能亦有严格要求。因为质量不同的硅石其效果各异,如使用含SiO_295％的硅石其电耗比含SiO_298％的硅石高11％。另外矿石的抗爆裂性差也是造成电耗高、炉况不正常的重要因素之一。因此,铁合金厂根据各自的炉型选择质量合适的原料基地是必要的。
Silicon series alloy smelting process, not only has a certain grain size into the furnace, but also on the SiO2, associated oxide content and ore smelting performance also have strict requirements. Because of the different effects of different quality silica, such as the use of silica containing SiO_295% of its electricity consumption is 11% higher than the silica containing SiO_298%. In addition, the anti-burst resistance of the ore is also caused by high power consumption, abnormal furnace one of the important factors. Therefore, the ferroalloy plant according to their furnace selection of the right quality of raw materials base is necessary.
