The influence of ordinary magnetite ratios on Hongge high-chromium vanadium-titanium magnetite (HCVTM) sinters was researched through sintering pot tests. The researches including yield, sintering ratio, tumbler index (TI), productivity, solid fuel consumption, reduction degradation index (RDI) and reduction index (RI) were tested and calculated. The addition of ordinary magnetite ore is an adjusting method to affect the chemical content and properties of sinter. In this work, with ordinary magnetite ratio increases, the yield decreases from 90.5% to 84.6%, and sinter ratio decreases slightly from 84.98% to 83.43%. The maximum of productivity is 3.52 tm-2h-1 with 15% ordinary magnetite and then decreases with increases of ordinary magnetite ratio. The TI decreases and the minimum of TI is 43.65% with 45% ordinary magnetite. 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 increase of ordinary magnetite ratios.
