Practice of Increasing Production and Efficiency of Hanbao Blast Furnace
The No.1 blast furnace strictly controls the variety and quality of raw material coke,reduces the impact of the change of coke variety on the blast furnace anterograde,and secondly,strictly controls the preparation speed under the tank to reduce the deterioration of the air permeability of powder into the furnace.When the wind temperature is affected by equipment factors,the humidification capacity and coke load are adjusted to control the theoretical combustion temperature of the blast furnace and ensure the stable and smooth operation of the blast furnace within a suitable range.Carry out"three-point inspection"on the equipment in front of the furnace in strict accordance with the safety standards,quantify the amount of iron out of the furnace,and discharge the slag iron in time.Strengthen the effective control of the gas volume and permeability resistance coefficient of the furnace belly to stabilize the furnace condition.The fuel ratio was reduced from 530 kg/t to 510 kg/t,and the coal ratio was increased from 125 kg/t to 140 kg/t,further reducing the cost of pig iron.
