A new ironmaking process named SC process has been developed. This process is characterized by the separation of such functions as reducing and smelting which are undertaken in two furnaces, a reduction furnace of a shaft type and a melting furnace of a coke bed type, and by the use of pulverized coal in a large quantity.Through the operation tests by a pilot plant of 8 t per day in production capacity, SC process has been confirmed to be useful one as an ironmaking process.On the basis of the results obtained by the pilot plant operation, a commercial plant of 2 400t per day in productivity having the following features has been designed.1) High productivity, being 2.5 times as large as that of blast furnace.2) High heat efficiency, competing with blast furnace.3) A wide use of non coking coal, being 70% of total coal.
