Under the condition of high concentrate ratio and deep bed sintering，fundamental sintering properties of iron ore fines and pot tests were conducted to find reasonable WPF proportion and iron ore matching. Pollutant emissions were also concerned during sintering. The key findings are summarized as follows: Under the conditions of 750mm bed height, WPF replacing 20% PB and 10% MAC (or 30% Brazilian Blend Fines (BRBF)), achieved the better RDI, TI, size, yield, productivity and other quality indicators. the sinter obtained. At 900m bed height and 4.6% coke rate was equivalent to that obtained at 750mm bed height and 5% coke rate in terms of yield, RDI and other quality indicators. At the same time, the solid fuel consumption of sintering was reduced by 3.5kg/t, and the emission of NO and SO2 per ton of sinter was reduced by 24% and 35% respectively. |
