Treatment of Molten Steel Slag for Cement Application ...

Steel slag can be an alternative in cement mineral admixture, partially as a substitute for blast furnace slag. A pyrometallugical process has been investigated to promote the chemical composition modification of molten steelmaking slag in a metallurgical reactor. Experiments were conducted by remelting 300 kg of steel slag followed by chemical modification of liquid slag. The modified slags ...

Modification of BOF Slag for Cement Manufacturing ...

The use of metallurgical slags in cement manufacturing depends on the phases that compose such slags, which are affected by changes in slag chemical composition as well as by cooling rates adopted during solidification. Two different slags were produced in a pilot scale metallurgical reactor by mixing additives into 300 kg of re-melted BOF slag followed by natural cooling or by adding of steel ...
