RESEARCH AND PRACTICE OF OPTIMIZING FERROSILICON SMELTING PROCESS WITH CALCIUM OXIDE
In order to improve the efficiency and quality of ferrosilicon smelting process and explore the core field of optimizing ferrosilicon smelting process by adding calcium oxide,the role of these technologies and strategies in the smelting process was analyzed through comprehensive experimental data and theoretical models.The results show that the slag in the later stage of ferrosilicon smelting is difficult to discharge,which increases the tapping time,and is not conducive to the stability of smelting parameters and the deep insertion of electrodes.By adding calcium oxide in sta-ges,it can promote slag discharge at the later stage of tapping in front of the furnace,shorten the tapping time,stabi-lize the parameters and increase the effective smelting time.
