Apr 01, 2000 · Liquid 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

Apr 19, 2012 · Extractive metallurgy of ironThe following raw materials are involved in manufacturing of iron: Iron ores (magnetite, hematite) – iron oxides with earth impurities; Coke, which is both reducing agent and fuel, providing heat for melting the metal and slag. Coke is produced from coking coals by heating them away from air. Limestone – calcium silicate fluxes, forming a fluid slag for removal gangue from the ore. Iron …

Iron and steelmaking process is energy intensive. Generally speaking, energy constitutes a significant portion of production cost, from 20% to 40%, according to the estimation from world steel association [7]. About 95% of energy for an integrated steelmaking plant comes from solid fuel (mainly coal), 3–4% from gaseous fuel and 1–2% from liquid fuel

steel manufacture

steel manufacture

Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called ‘sinter’. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal
