Practice of Wall Thickening Treatment for Hesteel No.3 Blast Furnace with Medium Thick Plate
In order to investigate the causes of wall thickening in Hesteel No.3 blast furnace with medium thick plate,it is clear that the main reasons for wall thickening in the No.3 blast furnace are the amount of block ore with poor thermal explosion performance,unstable slag making system,large fluctuations in sintered ore alkalinity,poor coke quality,and the influence of deep material lines.By taking timely and effective measures to fine tune various systems,supplemented by low-dose circulating coke insertion,the furnace condition was maintained smoothly,and the air was stopped for 4 hours.The furnace wall was cleaned by hot acid washing with clean coke,and the furnace condition was quickly restored to stability with minimal loss.The air volume was increased,and the output was restored to normal level.
