EXPERIMENTAL RESEARCH ON THE COMPREHENSIVE PERFORMANCE OF ULTRA-HIGH Al2O3 SINTERED ORE
For a long time,the research on the performance of high Al2O3 sintered ore in the industry has remained at the medium and low temperature stage,while there is relatively little research on the most critical high-temperature performance,which seriously limits the use of high aluminum resources.Faced with the decreasing low aluminum resources and the disappearance of some varieties,it seriously threatens the resource guarantee for industry development.Through systematic research on the performance of high Al2O3 sintered ore,and on the basis of balancing the impact of various performance indicators on the actual blast furnace,the focus is on improving the high-temperature soft melt dripping performance of sintered ore,solving the industry technical difficulties in the use of high Al2O3 sintered ore,and achieving good results in actual production.Based on technical measures such as complementary performance,structural optimization,and reasonable parameter control,the performance defects of high aluminum resource sintering have been overcome.While expanding resource guarantee supply,the space for cost reduction of molten iron has also been increased.
