Abstract
When reducing iron ores at temperatures below their melting point, the end product will be a porous mass of more or less completely reduced iron; this product is called sponge iron.
Sweden utilizes a greater tonnage of sponge iron than any other country at the present time. This report deals with Swedish experience and technique in the use of sponge iron in electric arc furnaces.
