Producing Portland cement from iron and steel slags and lineAbstract. The slags from blast furnace (iron making ) and converter (steel making) after magnetic separation are mixed with line of six differ- ent compositions. The ground materials are fired in a pilot plant scale rotary kiln to 1350 C for 1 h. The clinker is cooled, crushed, mixed with 3% gypsum, and ground to fineness.An Overview of Utilization of Steel Slag - ScienceDirectThe physical and chemical characteristics of steel slag were analyzed and then the research progress of steel slag utilization at home and abroad as recycled raw . construction, cement additive and concrete admixture, materials for waste water or gas treatment, construction materials and fertilizer in agriculture production.
