More2015-9-10 The production of 1 ton of iron requires 1.4 tons of ore or other iron bearing material; 0.5 to 0.65 tons of coke; 0.25 tons of limestone or dolomite; and 1.8 to 2 tons of air. Byproducts consist of 0.2 to 0.4 tons of slag, and 2.5 to 3.5 tons of blast furnace gas containing up to 100 pounds (lb) of dust.
MoreThe first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in the form of liquid at approximately 1450 C, called as 'hot ...

In general, the process involves (1) beneficiation of the iron ore, (2) either direct-reduction or reduction in an iron blast furnace, (3) processing in steelmaking furnaces, and (4) casting. Ironmaking
MoreIntroduction. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water-powered hammers replaced ...

MoreThe process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel ...
