In the melting zone the iron begins to melt and forms strongly carbon-containing pig iron! Tapping zone. The molten pig iron finally collects in the hearth of the blast furnace together with the slag, which is also liquid. Due to the higher density of the pig iron, the pig iron can be cut off at the lowest point of the blast furnace (called ...

The main raw materials for Steel production in a blast furnace are Iron ore, limestone, coke, and some scrap steel. These materials are charged into the blast furnace from the top and converted into molten pig iron. Next, a current of air is blown through the molten pig iron containing carbon, silicon, and manganese.

This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.

Iron-making; This is the first step in the manufacturing of pure steel. In this step, the raw materials like iron ore, coal and lime are melted in a blast furnace. This results in the formation of molten iron, also known as hot metal, which still contains 4-4.5% of carbon and other impurities, which makes it brittle.
