The time consumed in the steel making process is far less than all the previous methods. For the global energy crisis in the 70's and to reduce the processing period, continuous casting method was introduced. In this integrated manufacturing process, in a single continuous process pig iron is converted to steel. Location of Iron and Steel ...

1A Manufacturing Process for Iron and Steel

Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Manufacture of Steel - Steel Manufacturing Process and Steps

The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

1A Manufacturing Process for Iron and Steel

Iron Ore to Steel. Raw material for manufacturing the TMT Bar are iron ore, coal, dolomite. In this process raw materials are piled, recovered and mixed in required proportion. The iron ore experiences beneficiation procedure to raise the iron substance. At this point metal fines are gathered to shape a mass of pellets and sinter to improve ...

Jan 20, 2017· The process of turning raw product into finished stainless steel is a lengthy one, but it can be simplified into six steps. Let's look at this incredible process. Making the Iron. To create pure steel, the products that go into it- lime, coke and iron ore- must be made into iron.

Iron processing - Iron making | Britannica

The molten iron is subjected to pre treatment and is converted to steel in a convertor or a Basic oxygen Furnace. Oxygen is blown into the BOF which contains the molten iron from the blast furnace. This oxygen combines with carbon in the iron and carbon is eliminated in the form of carbon di oxide.

12.5 Iron And Steel Production

Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1.
