METHOD FOR PRETREATING RAW MATERIAL FOR SINTERING, AND METHOD FOR MANUFACTURING SINTERED ORE

摘要

PROBLEM TO BE SOLVED: To provide a simplified and efficient method for pelletizing a raw material for sintering in manufacturing the raw material for sintering for iron manufacture.;SOLUTION: In this method for pretreating the raw material for sintering, the raw material for sintering which contains iron ore 1-1 or a raw material mixture 1-2 is pressed and crushed using a roller press crusher 2, which is pelletized in a pelletizer 4 together with another raw material 3 for sintering with the addition of a binder 20. In particular, the above raw material for sintering contains 20 to 100 mass% (dry) of Maramanba ore or pisolite ore or Maramanba ore and pisolite ore.;COPYRIGHT: (C)2007,JPO&INPIT
