Abstract

A process to manufacture previously formed slags for the production of steel, metallurgically very active and that attack very little to the basic refractory materials, which consist of CaO- (Al2O3 and/or Fe2O3) -MgO eventually, in addition to silicic acid, oxide titanium and sodium oxide, individually or in combination, characterized in that an intimate mixture of materials is made from the group consisting of limestone, dolomite, fragments of dolomite, rough dolomite, bauxite, raw bauxite, red mud; why the mixture dries; because it is then sintered at about 1150º in an appropriate device; and because the composition of the mixture is chosen in such a way that the content of MgO in the final product is 8 to 15 percent by weight and because the final product has the following ratios (see formula) (Machine-translation by Google Translate, not legally binding)
