Brittle molded article and briquette using the same

摘要

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).
