MANUFACTURING METHOD OF SMALL LUMP OF RAW MATERIAL FOR IRON |
摘要 |
PROBLEM TO BE SOLVED: To provide a manufacturing method of a high-density, small-lump raw material for iron which is automatically cut of and charged without causing bridging in a furnace-top hopper in iron making or casting operation. SOLUTION: Only steel pieces of >=3 mm thick which are by-product in a steel mill are shredded by a shredder in advance to manufacture small pieces of 100-200 mm square. The small pieces are charged in the shredder by 10-30% to the steel plates of <=3 mm thick as by-product to manufacture high-density, small-lump and round steelmaking raw materials.
