METHOD FOR PRODUCING BRIQUETTE FOR RAW MATERIAL FOR IRON MAKING

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a briquette for the raw material for iron making by which gound cut powder can effectively be reutilized. SOLUTION: A flocculent aggregate B containing ground cut powder of iron based metal and a grinding solution containing oil and water is subjected to compressive molding to produce a brittle compact C in which the fibrous gound cut powder is coarsely sheared, and also, the surplus water and oil are removed. This brittle compact C is pulverized to more finely shear the gound cut powder. The powder is mixed with a solidifying auxiliary D to produce powder E containing the solidifying auxiliary D. The powder E is solidified by compressive molding to produce a water-containing briquette E. Then, the water contained in the water-containing briquette F is removed.
