Wrought Iron Production The production of wrought iron or steel is a process containing two main stages The first stage is to produce pig iron from iron ore in a blast furnace Alternatively it may be directly reduced The second is to make wrought iron or steel from pig iron by puddling process a further cially available iron is classified based on purity and the abundance of additives
