COMPARATIVE ANALYSIS OF THE MINERALOGICAL COMPOSITION AND METALLURGICAL PROPERTIES OF SINTERS OBTAINED FROM IRON-ORE-BEARING CHARGES OF DIFFERENT ORIGINS

摘要

A study is made to determine how the main genetic groups of iron-ore-bearing components in the sintering charges used at the MMK affect the sintering operation and the quality of the finished product (shallow bed and a complex multi-component charge). Recommendations are presented for improving efficiency in the production of low-basicity (1.6 + - 0.1) sinter in a shallow (260 mm high) bed with certain proportions of different genetic types of components in the iron-ore-bearing part of the charge.
