The Basics of Iron and Steel Making

Moving on to steelmaking processes, the first thing is to mention that there are two basic ways of making steel. So far, we have considered how iron is extracted from its ore, principally using the blast furnace. Steel producing sites which use blast furnaces, which make iron which is refined into steel, are termed 'integrated sites'.
