    摘要: Novel utilizations of strontium aluminate, a by-product of the manufacture of strontium, are disclosed in connection with the art of steelmaking. It is useful as a synthetic slag covering for molten iron or steel, as well as in the foaming slag practice, as a backfilling material for spaces between the safety lining and the working lining of a ladle, as a major component for a blend from which are made pellets or briquettes useful as a slag conditioner, as an additive to calcium aluminate which has the effect of substantially lowering the melting point of calcium aluminate, as a tracer material to determine the source of impurities, and as a binder to recycle metal-containing dust.

    摘要: For use with an electric steelmaking furnace, a briquette is provided which incorporates a suitable binder, a first quantity of carbon fines, and a second quantity of a material in powdered form, the latter material being selected from the group consisiting of lime, dolime, limestone, dolomite, magnesia, magnesium carbonate, other suitable carbonates, and mixtures thereof. The second quantity being large enough to suppress the slippery nature of the carbon fines, and to density the briquette to the extent necessary to cause it to sink into the furnace melt.

    摘要: A method is provided by which rice hull ash is pelletized for use in steelmaking. The rice hull ash is blended with lime or dolime, and also with a mixture of water and molasses. This generates heat as the lime and water react to form lime hydroxide, a known binder. The heat thus generated reduces the energy required for drying the pellets.
