industrial processing wastes office of solid waste, 1988, 28. ibid steelmaki ng all contemporary steelmaking processes convert pig iron, scrap, or direct-reduced iron, or mixtures of these, into steel by a refining process that lowers the carbon and silicon content and removes impuritiesliquid iron collects at the bottom of the blast furnace, underneath a layer of slag. the blacksmith periodically lets the liquid iron flow out and cool. At this point, the liquid iron typically flows through a channel and into a bed of sand. once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with tons (1.8 flow chart Of pig iron production process grinding mill china. ron and steel production 121 process descriptio into the blast furnace donawitzsteelmaking or the oxygen converter process is a method of primary steelmaking in which carbonrich molten pig iron is made into steelontact supplier hot strip mill process flow chart diagram.mar 07, 2017 As a result, chinese pig iron has become an attractive raw material. but the use of 100 percent pig iron restricts the melting process to the chemistry of the pig iron, which can vary wildly. what goes in must come out, and the foundry using 100 percent pig iron has little control over the metallurgy of the iron that goes into its products.
