Review Dissolution Behavior of Lime into Steelmaking Slag

Review 1. Introduction In steelmaking processes, lime is the most important flux used to make slag. Lime is made by the calcination of limestone by a rotary kiln or shaft furnace, and its size range is generally 7–35 mm in diameter. Its main component is CaO and, by the JIS (Japanese Industrial Standard), the CaO content has to be 93% or more and the residual CO 2 has to be lower than 2%. In ...

The proper conditions of this process, such as the slag ...
