| Abstract: | Keep slag operation is adopted in semisteel making with 150 t converter in Cheng Steel.It makes a good result of desulfurization and dephosphorization by means of end cost analysis and spreading lime and dolomite on bottom before blowing on,and at the same time the lining got protected,raw and auxiliary materials saved,production cost reduced,converter life increased to 7 000 heats,no spitting occurred. |
