Practice of Increasing the Top Pressure of Beiying Blast Furnace
High pressure operation can not only improve the smelting intensity of blast furnace,but also effectively reduce the coke ratio entering the furnace.A theoretical study was conducted on the top pressure lifting of the Beiying 3 200 m3 blast furnace,and long-term operational experience was summarized.After taking measures such as improving the quality of raw materials and fuels,increasing the kinetic energy of the blast,and optimizing the loading system,the top pressure gradually increased to over 250 kPa.This not only enhanced the stability of the blast furnace condition,but also improved the gas utilization rate,reduced the coke ratio,increased the TRT power generation,and achieved considerable economic benefits.
