在掌握以石油焦和木屑的混合物代替大部分木炭炼硅的新工艺过程中出现了一定的困难。首先,大量采用还原活性低的石油焦(每吨硅用500～600kg),但由于它是活性小的还原剂,会导致熔炼的热行程,炉喉过度烧结,结果使技术经济指标变坏。此外,为使炉料疏松而使用大量木屑(每
There are some difficulties in mastering the new process of replacing most of the charcoal with silicon by using a mixture of petroleum coke and sawdust. First of all, a large amount of petroleum coke with a low reducing activity (500-600 kg per ton of silicon) is widely used. However, because it is a less active reducing agent, the heat stroke of smelting and excessive sintering of the throat can result in deterioration of technical and economic indicators. In addition, large quantities of sawdust are used to loosen the charge (each
