An Infographic of the Iron and Steel Manufacturing Process By Tracey Sinha-Spinks 06.04.2015 Steel production is a 24-hour-a-day, 365-day-a-year process, dependent on a consistent supply of raw materials and huge amounts of energy.
The production of iron or steel is a process consisting of two main stages. In the first stage pig iron is produced in a blast furnace. Alternatively, it may be directly reduced. In the second stage, pig iron is converted to wrought iron, steel, or cast iron.

The steam–iron process is one of the oldest methods of producing hydrogen. It is a cyclic process for water cleavage, whereby coal is consumed. Coal is gassified to a lean reducing gas, containing carbon monoxide and hydrogen.
The casting process can have a significant effect on the structure and properties of gray iron casting. Gray iron is the most versatile of all foundry metals. ... ductile cast iron production slows down the growth of graphite and allows the carbon to separate as spheroidal graphite particles instead.
Cast Iron Production When breaking out the casting the sand mould is destroyed, but of course new moulds can be made from the pattern using the same sand after it has been re-cycled. Casting: This is the final part of the process and the one most people associate with foundries.

2. PRODUCTION OF IRON AND STEEL POWDERS 8 2.3 The Höganäs Sponge Iron Process The Höganäs sponge iron process, is essentially a chemical process in which ﬁnely divided iron ore is being reduced with coke breeze yielding a spongy mass of solid metallic iron, which can readily be comminuted to iron powder. The iron ore used at
Cost of Production of Pig Iron. Cost of production of pig steel from ore in the electric furnace is, of course, the main stumbling block to the success of such a process. As yet not enough practical work has been done to give conclusive figures.
