Abstract: 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.

Abstract: 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.

Abstract: There is disclosed a briquette and a method of making the briquette, wherein the briquette includes a first quantity of carbon fines and a second quantity of a material in powdered form which contains iron or a similar metal, or an oxide thereof, the second quantity being sufficiently large that the slippery nature of the carbon fines is suppressed, and the overall density of the briquette is increased.
