Technology and Processes Behind Steel Production
Jul 20 2017 · Blast furnaces produce most of the pig iron or hot metal used in the steel industry today from a mixture of iron oxide ore and limestone flux. A mixture or burden of iron ore limestone flux and coal is heated in a blast furnace to produce molten iron or pig iron from which steel is made.

Apr 04 2012 · A transition period from carbon- to hydrogen-based iron and steel production is unavoidable. Carbon serves until now as a main chemical reactant to convert iron-bearing materials to iron and steel and CO 2 is an unavoidable by-product of this reaction. The amount of carbon required is dictated by laws of chemistry physics and thermodynamics.

The Wealden iron industry was located in the Weald of south-eastern England.It was formerly an important industry producing a large proportion of the bar iron made in England in the 16th century and most British cannon until about 1770. Ironmaking in the Weald used ironstone from various clay beds and was fuelled by charcoal made from trees in the heavily wooded landscape.

The blast furnace is the prior step in the steel manufacturing process to remove oxygen from the iron ore so that it can be used in making steel and this process of removing oxygen is known as reducing where hot air is injected into a continuous feed of coke sinter and lime. The resultant of the reducing process is the liquid iron which is then transported to the basic oxygen furnace.
