EFFECT OF ORDINARY MAGNETITE RATIOS ON PROPERTIES, PRODUCTIVITY, AND STRENGTH OF HONGGE HIGH-CHROMIUM VANADIUM-TITANIUM MAGNETITE SINTERS

摘要

The sintering pot test was used to research the influence of ordinary magnetite (OM) ratios on Hongge high-chromium vanadium-titanium magnetite (HCVTM) sinters. The yield, sintering ratio, tumbler index (TI), productivity, solid fuel consumption, reduction degradation index (RDI) and reduction index (RI) were tested and calculated. In this work, the yield decreases from 90.5% to 84.6%, and sinter ratio decreases slightly from 84.98%) to 83.43%) with increasing OM ratios. The maximum of productivity is 3.52 t-m~(-2)-h~(-1) with 15% OM. The TI first decreases and then increases with increasing OM ratios, and the minimum of TI is 43.65% with 45% OM. The RI increases from 50.7% to 70.9%, and the solid fuel consumption rises from 55.25 kg-t"1 to 59.10 kg-t"1 while the RDI deteriorates from 96.7% to 50.7%) with increasing OM ratios.
