Properties and Uses of Ironmaking slag

 · Physical properties of BF slag. BF slag is tapped from the furnace as a liquid, which contains gases held in solution. The density of liquid slag at around deg C can vary in a range of 2.68 tons/cum to 2.84 tons/cum. The volume of gases (carbon di oxide, nitrogen, and oxygen) dissolved in 1 cubic metre of liquid BF gas at around deg C.

Slag

Using slag as a raw material is not a new concept. Recently its use has become more prevalent as plants look to reduce CO2 emissions. Because the calcium in slag exists as CaO, the use of slag as a raw material reduces CaCO3, and the CO2 emissions per ton of clinker production are reduced. It's this reduction in CO2 emissions per ton of clinker production which allows plants that are fan.

Steel Converter Slag as a Raw Material for Precipitation of …

In this work we study the possibility of utilizing steel converter slag, a byproduct of steel manufacturing, for production of pure calcium carbonate. The dissolution of calcium from steel converter slag by using acetic acid as a solvent and the precipitation of pure calcium carbonate from the resulting solution were experimentally investigated. It was found that, while strong solutions of.

Basics of slag production

 · Traditionally it has been used mainly as an aggregate but for some types there are other applications, such as a raw material for cement or as a fertiliser. Slag, as the term will be used here, is any siliceous melt that arises in significant quantity from the various processes used in the production of iron and steel, and more particularly the solid materials that forms when such melts cool.
