Study on the Activity of the Hearth of the No.1 5 100 m3 Blast Furnace in Shangang
Shangang Rizhao Company actively explores suitable quality control standards for coke in 5 100 m3 blast furnaces to reduce the accumulation of dead coke piles in the furnace hearth.At the same time,by optimizing the operating system,improving the permeability of the furnace hearth,optimizing the thermal system and slag making system of the blast furnace,and other measures,the general activity of the blast furnace hearth,which is not easy to accept high gas volume from the furnace belly,and the problems of high total pressure difference,inactive central airflow,and easy fluctuation of edge airflow in the blast furnace have been solved.The blast energy of the blast furnace has increased from the daily control of 120～125 kJ/s to 130～135 kJ/s,and the furnace condition is stable and smooth.The economic and technical indicators of the blast furnace are good.
