In response to the issue that the decrease in permeability impairs the sintering quality during the production of a 900 mm ultra-thick bed on a 405 m² sintering machine, it was analyzed that the main reasons for the decrease in permeability under thick bed operation were the increase in static pressure at the lower part of the bed and the thickening of the over-wet layer and combustion zone. After taking measures such as increasing the temperature of the sintering mixture, optimizing the water addition to the sintering mixture, reducing the ignition intensity, and rationally controlling the distribution of sintering airflow, the bed thickness gradually stabilized at 880 mm to 900 mm. The solid fuel consumption decreased from 56.58 kg/t to 49.63 kg/t, and the power consumption per ton of ore decreased from 46.77 (kW·h)/t to 36.50 (kW·h)/t. Meanwhile, the sintering utilization coefficient increased from 1.241 t/(m²·h)to 1.402 t/(m²·h), which enabled high-quality production with an ultra-thick bed on the sintering process.
