1. In the use of desulfurization of high-carbon ferrochrome powder should be promoted in the smelting of silicon, carbon ratio, because of the aluminum alloy in the silicon, carbon composition of aluminum alloy sulfur content has a significant impact.
2. After desulfurization of high carbon ferrochrome powder, the coal ash composition should be accurately manipulated. When the coal ash magnesium oxide and calcium hydroxide are not enough, the appropriate lime powder should be added.
3. To improve the temperature control can improve the use effect of desulfurization of high carbon ferrochrome powder, generally should be the temperature control operation at about 1650~1700℃ as well.
