Sulphur and silicon control in ferrochromium production

If ferrochromium is required with less than 0,03% sulphur and with less than 2,5% silicon, the reducing potential of the slag and the activity or relative concentration of silica in the slag can be lowered to decrease the reduction of silica to silicon. Decreased reducing potential may be achieved either by lesser additions of carbonaceous ...
