用数值模拟方法研究了工艺因素对硅铁在铁液中熔化过程的影响。结果表明 :硅铁浸入铁液至完全熔化分为两个时期 ,即铁壳期和熔化期 ;硅铁自浸入铁液至完全熔化的时间 ,随着铁液初始温度的升高、硅铁尺寸的减小和硅铁含硅量增加而缩短 ;如果按照铁壳期和熔化期来划分硅铁浸入铁液至完全熔化的时间 ,铁液初始温度和硅铁尺寸对铁壳期的影响大 ,而对熔化期的影响较小。 The effects of technological factors on the melting process of ferrosilicon in molten iron were studied by numerical simulation. The results show that the ferrosilicon is immersed in molten iron until it is completely melted and divided into two phases, ie, the shell phase and the melting phase. When the ferrosilicon is immersed in the molten iron until it completely melts, with the initial temperature of the molten iron increasing, And the silicon content of silicon ferrite increased shortening; if according to the iron shell and the melting period to divide ferrosilicon immersed in molten iron to completely melt time, the initial temperature of molten iron and ferrosilicon size of the steel shell period, While the impact on the melting period smaller.
