During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

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. According to the World Steel Association, world crude steel production has increased from 851 million tonnes (Mt) in 2001 to 1,606 Mt in 2013 and world average steel use per capita has steadily increased from 150kg in 2001 to 225 kg in 2013.

Modern-day steel production makes use of both traditional raw materials (iron) and recycled materials to turn them into steel. With this in mind, here are the 6 steps to modern steel production explained. Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made.

Apr 16, 2016· Steelmaking flow chart 6. Bessemer Converter Process The Bessemer Converter Process was first developed in 1856. the original process was suitable for only low ‘P’ iron as it used acidic refractory lining. The basic bessemer process, suitable for high ‘P’ hot metal was developed later by Thomas Gilchrist and is known as Thomas process.
Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production). After the BF-BOF process, molten steel is controlled to a target composition ...
