Niccochromite smelting process for producing nickel chromium pig iron

This invention provides a nikel chromite smelting nikel chromic pig-iron technology, which uses the conventional smelting technology and fixture, wherein in the smelting course, the weight proportion of the additive with the sinter mine as follows:fluoriteíí0.5í½ 0.8úÑú”dolomiteíí1úÑú”lime stoneíí8úÑú¼wherein the sinter mine is made from Albania nikel chromite, compraring to the present technology, the proportion fo the additive with the sinter mine of this techonology in this invention can lower the affect to the furnace tempreture from the chorome, and can avoid some accidents such as crucible burning out because of the excessive high fluorin content; the magnesium in the dolomite can slove the problem that the chrome causes the bad flowability of the molten iron; and the dolomite can provide alkalinity and poise the said two additives.íííííí
