  • Publication number: 20070051200
    Abstract: 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.

  • Patent number: 6773486
    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.

  • Patent number: 6051049
    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.

  • Patent number: 5916827
    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.

  • Patent number: 3966167
    Abstract: This invention provides a novel sideboard construction, which includes at least one hanger rod of which a portion is embedded in the material of the sideboard, the sideboard also having a plate member equipped with a non-circular opening through which the hanger rod passes. The hanger rod section is also non-circular in the region of the plate member, and the relative dimensions of these two are such that the rod is rotatable within the opening between a first position in which it binds against edge portions of the opening, and a second position in which it does not so bind. The rod in the second position can be moved lengthwise through the opening, and in the first position is "jammed" or caught in the opening, and thus capable of supporting the weight of the sideboard as the latter is suspended inside the top of an open-topped metal ingot mold. The material of the rod is softer than the material defining the opening.
