research on oxygen converter slag recycling when recycling of up to 3 t of demetallized slag into charge of 170 t converter had beneficial effects on parameters of steel refining, that followed from early slag formation in the process.
Extraction of iron and its conversion into steel Steel Essential Chemical Industry Steel is one of the most widely used materials, particularly in construction and engineering and in the manufacture of cars.
Based on process, the global market for iron and steel slag can be segmented into blast furnace slag and steelmaking slag. The blast furnace slag can be further divided into granulated blast ...
The broad applications where iron and steel slag are used comprise building and construction, railways, and fertilizers. Of these, building and construction industry is the leading segment as it held the major share in 2016 and is anticipated to rise at an attractive pace over the forecast period.
Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components from the pig iron and refine it to produce strong steel.
The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide. This is an endothermic reaction, absorbing heat from the furnace.

Apr 07, 1981· A process for recovering and utilizing useful substances from a molten metal produced, when manufacturing a steel slag cement from a steel slag discharged from a topblowing oxygen converter, during a reduction treatment of steel slag, which comprises the steps of: subjecting, in an acidic refining furnace, said molten metal to a primary oxidation refining treatment and a .
Figure 8 The liquid steel is tapped (poured) into a ladle and the slag is tapped into a separate 'slag pot'. This photo shows a later stage when the molten slag is poured from the slag pot. The slag is treated so that any iron left is recovered and the residue is then used as an aggregate.
