Evaluation of Basic Oxygen Furnace (BOF) material

2016-7-15  Basic Oxygen Furnace (BOF) slag has many prismatic angles, is massive, and has a high hardness that meets the requirements of the aggregate used in asphalt concrete. BOF has a higher proportion of CaO but a lower proportion of SiO 2 than natural (gravel) aggregate (NA) because CaO is a lipophilic molecule while SiO 2 is a hydrophilic molecule ...

Basic oxygen furnace slag: Review of current and

2020-4-1  1.4.2. The basic oxygen furnace (BOF) The BOF process forms part of the primary steel production route, which also incorporates the BF process. In a BF, the iron ore, limestone and fuel are continuously supplied through the top section of the furnace, while heated air is forced into the lower section (Geerdes, Toxopeus, Van der fliet, 2009).The end products are usually molten metal and slag ...

Basic Oxygen Furnace Slag (BOFS) Graded

2021-4-15  Raw materials and production processes. BOFS graded aggregates are by-products of BOF steelmaking in a wholly integrated steel mill. Their main chemical compositions are CaO, SiO 2, Al 2 O 3, Fe 2 O 3, etc.The molten slag is cooled and solidified into basic oxygen furnace slag, which then undergoes crushing, magnetic separation, and screening to make BOFS graded aggregates.
