Basic oxygen furnace (BOF) slag is a main byproduct produced during the converter steelmaking process. The poor grindability of BOF slag limits its added-value application. In this paper, the grinding characteristics of unmodified and reconstructed BOF slag were compared. Additionally, the grinding property of reconstructed steel slag was also studied after SiC ing.

Grinding of blast furnace slag is conventionally performed in a tube mill with a dryer, which is a power-intensive option. Energy efficiency of this process can be improved by grinding the blast furnca slag using vertical roller mills (VRM) or by using a VRM as a pre-grinding step for the tube mills.
The slag was collected and cooled to ambient temperature in an open atmosphere at the production site. The sludge on the other hand was generated during the process of remoulding the steel wires to assume desired shapes and sizes. Both materials were prepared by grinding to 45 μm fineness. While the steel slag undergoes no further drying ...
Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is ...
