Low Temperature Reduction

The influences of various factors, such as oxygen enrichment time, oxygen enrichment load, and ignition temperature, on the technical indices and sintering performance in the vanadium-titanium magnetite sintering process are simulated using sinter pot experiments. The experiments are based on the field production parameters of a sintering trolley in a steel enterprise in southwest China. Prolonged oxygen enrichment time results in the gradual increase in vertical sintering speed, sintering utilization coefficient, sintered ore yield, sintered ore drum strength, and reductivity. However, the low-temperature reduction pulverability of the sintered ore deteriorates. Oxygen enrichment load increases from 0 m3/h to 2.9 m3/h, and yield increases by 1.1%, while the vertical sintering speed and utilization coefficient increase slightly. Sintered ore drum strength increases from 65.33% to 68.00%, antiwear index decreases to 0.47%, and low-temperature reduction pulverability decreases from 65.07% to 62.85%. The increased ignition temperature is beneficial to improve the drum strength and yield of the ore but reduces the vertical sintering speed and utilization coefficient. With the increase in ignition temperature, the low-temperature reduction pulverability tends to increase first and then decrease. Changes in oxygen time, oxygen enrichment load, and ignition temperature have no significant effects on the soft melting performance of the sintered ore.

Low Temperature Reduction

In order to use resonably fuel resources and reduce cost of manufacture, the effects of coke and coal powder on chemical coposition and metallurgical properties of sinter were studied with the iron ore blender as the iron-contained materials. Results shown that the reducibility at 900°C was slightly improved and the low temperature reduction degradation index was worsened with the coke powder as the solid fuel relative to coal powder under the equal calorific value condition. However, with the increasing of solid fuel ratio, the mechanical strength and low temperature reduction degradation index was improved.
