Development of Heat Recovery System from Steelmaking Slag
3.1 Design of Slag Heat Recovery Pilot Plant The slag heat recovery pilot plant which was built in this development is a counterflow packed bed-type heat exchanger like the one used in coke dry quenching (CDQ). However, when compared in the same condi-tions (same volume and charging temperature), the amount of heat recovered by the slag heat recovery plant is only about 1/2 of that recovered in the …

FACT SHEET Steel industry co-products
recovered slag is used internally in the steelmaking furnace or sinter plant, while approximately 50% of the recovered slag is used externally in construction applications, primarily roads. One of the main barriers to using some steelmaking slags is their high content of free lime, which is not ideal for construction applications.
Iron and Steel Slag Statistics and Information
Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the
