Analysis of Temperature Control Technology for the Side Wall of Large Blast Furnace Hearth
The increase in temperature on the side walls of the blast furnace hearth will seriously threaten the service life of the blast furnace.In order to effectively control the temperature on the side walls of the blast furnace hearth and extend the service life of the blast furnace,starting from the current statistical data of the temperature of the side walls of large blast furnaces in China,based on the requirements of the furnace structure and materials,this paper analyzes the influencing factors of the temperature of the side walls of the furnace from the perspective of heat transfer and proposes corresponding control technologies.The results indicate that technical measures such as controlling smelting intensity,stabilizing iron mouth depth,increasing porosity of dead material columns,furnace hearth grouting,adding titanium to protect the furnace,and strengthening cooling system management can effectively control the temperature of furnace hearth sidewalls.
