  • Briquette for raw material for iron manufacture and briquette for introduction into slag generating apparatus
    Patent number: 7438740
    Abstract: With the object of effective utilization of a fine powder generated during comminution of a crude material for iron manufacture, a briquette is provided which comprises a porous brittle molded body with a bulk specific gravity of 1.5 or more which is obtained by compression molding a molding composition comprising a fine powder generated during comminution of a crude material for iron manufacture and a reinforcing portion for reinforcing the brittle molded body. Further, with the object of effective reuse of used alumina grinding stones, a briquette is provided which comprises a porous brittle molded body obtained by compression molding a molding composition comprising a comminuted powder of a used alumina grinding stone and a cotton-like aggregate comprising a grinding powder of a ferrous metal and a grinding liquid, and a reinforcing portion for reinforcing the brittle molded body.

  • Method of Forming a Briquette
    Publication number: 20080179788
    Abstract: A brittle molded body (Z) obtained by compression molding into a prescribed shape a flocculent agglomerate (C) comprising ferrous metal shavings and a grinding liquid containing oil and water, the brittle molded body (Z) having a bulk specific gravity of at least 1.5. On the surface side of the brittle molded body (Z) is formed a strengthened layer (K) of higher density and higher hardness than on the inner side. A strengthened briquette (B) is obtained by impregnating a solidification aid D into this brittle molded body (Z).
