| Abstract Scope |
The effects of adding ratio of boron-iron and different roasting temperatures on the compressive strength of boron-containing pellets and the reduction swelling index of pellets were studied. The results show that the compressive strength of pellets decreases from 3125 N to 2933 N, and the reduction swelling index of pellets increases from 13.12 % to 18.40 %, with the increase of the ratio of boron iron ore powder from 0 to 5 % at the roasting temperature of 1250 °C. When the roasting temperature is reduced to 1200 °C, the swelling index rate of pellets with 5 % boron iron concentrate powder is reduced to 14.33 %, which meets the demand of blast furnace. The microstructure of borax pellets at different temperatures was observed. It was found that under the condition of low temperature, the formation of low melting point substances decreased significantly. |
