Mfg. ferroalloy contg. silicon - by briquetting mixt. of crushed ore and carbonaceous reductant and smelting with crushed silica

摘要

Ore containing the required metals is finely crushed and mixed with powdered carbonaceous reducing agent. The resulting pulverised mixture is moulded into briquettes and the briquettes mixed with a powdered silica rock. The resulting change is put in a smelting furnace and reduced at =2,000 degrees C. Useful for producing the Fe-Si-Al ferro alloys.
