发明名称 METHOD FOR PRODUCING HIGH QUALITY AND LOW SiO2 SINTERED ORE FOR BLAST FURNACE
摘要 PROBLEM TO BE SOLVED: To stably produce sintered ore excellent in the reducibility, reduction powdering resistance at the time of reduction, strength and characteristic at high temperature, etc., in a high productivity and a high yield, using a ore containing >=5.0 wt.% of high crystallized water which is contained >=25 wt.% of the mixed raw material. SOLUTION: The sintered ore having <=4.6 wt.% SiO2 content, 1.0-3.0 CaO/ SiO2 content ratio by wt.% and >0.5 wt.% MgO content in the sintered ore product, is produced. Using one or both of magnesite and brucite as sub-raw materials, and without using SiO2.MgO and CaO.MgO the slag component composition in the sintered ore product is adjusted. Neither the SiO2.MgO, such as serpentine nor the CaO.MgO, such as dolomite is used as a sub-raw material.
