Abstract: There is provided a process for producing a high-manganese iron alloy from a manganese ore and/or a pre-reduced product thereof in a top and bottom blown converter type reaction vessel holding molten iron or a molten manganese iron alloy, together with a molten slag, said molten iron or alloy and said molten slag being the products of a separate smelting furnace, gas being blown into said vessel through a bottom blowing nozzle, said process comprising charging said vessel with a supply of raw materials including at least one source of manganese and iron selected from a manganese ore containing manganese oxide and iron oxide and a pre-reduced product thereof, a solid carbonaceous substance and a slag forming agent, while simultaneously blowing gas selected from oxygen and a gas containing oxygen into said vessel through a top blowing lance to burn said carbonaceous substance so as to heat, melt and reduce said raw materials to form a melt containing manganese oxide and iron oxide; supplying an additional carbo

Abstract: A process which enables high-chromium alloy such as ferrochromium heretofore obtained by the use of electricity to be produced less expensively in higher yield of chromium by the smelting reduction using solid carbonaceous material such as coke in the place of electricity.The process of smelting reduction is so performed in the top and bottom blowing converter divided into two stages: the first stage for carrying out the converter operation under continued supply of the raw materials containing pre-reduced chromium oxide (chromium ore) and the second stage for carrying out the converter operation under suspended supply of the raw materials containing the pre-reduced chromium oxide, and the first stage of converter operation is carried out under conditions such that the temperature of the molten metal remains at or below 1,650.degree.
