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.
