USAProcess of making steel by melting sponge
Sponge iron produced by direct reduction is melted in an electric arc furnace in which a pool of liquid metal is maintained. To ensure that liquid carbon-containing iron for forming the pool is available in adequate quantities and that the process can be carried out with the highest possible economy the sponge iron is reacted in an electric arc furnace on a bath of liquid carbon-containing

A process for producing pig iron is described which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace.
