in order to obtain low silicon iron for steelmaking the reduction process of silicon must be controlled in blast furnace.
为了获得低硅炼钢生铁,必须控制高炉内硅的还原过程。
it is suitable for production transformation of the ore furnace producing industrial silicon and silicon iron because of no need for technical renovation.
最适合生产工业硅及硅铁的矿热炉的转产,无须进行技术改造。
therefore transportation of sulphuric acid valve is usually a high silicon iron pump (casting and machining difficult), high-alloy stainless steel pumps (on the 20th alloy) manufacturing.
