Briquette for raw material for iron manufacture and briquette for introduction into slag generating apparatus |
摘要 |
With the object of effective utilization of a fine powder generated during comminution of a crude material for iron manufacture, a briquette (B1) is provided which comprises a porous brittle molded body (Z1) with a bulk specific gravity of 1.5 or more which is obtained by compression molding of a molding composition comprising a fine powder (MN) generated during comminution of a crude material for iron manufacture and a reinforcing portion (K1) for reinforcing the brittle molded body (Z1). Further, with the object of effective reuse of used alumina grinding stones, a briquette (B2) is provided which comprises a porous brittle molded body (Z2) obtained by compression molding of a molding composition comprising a comminuted powder of a used alumina grinding stone (A) and a cotton-like aggregate (M) comprising a grinding powder of a ferrous metal and a grinding liquid, and a reinforcing portion (K2) for reinforcing the brittle molded body (Z2). <IMAGE> |
