Operating verification of the rotating-hearth furnace firing system

The rusults of investigating show decrease the degree of the burner loading leads to a certain increasing of the optimal value of the air surplus factor. Consiquently, the composition of the furnace atmosphere changes which has an influence on the loss of steel in scaling formed. Maintaining the pressure of the furnace atmosphere in all operating conditions is not always satisfactory, which results in the change of the change heating quality and the furnace economy.
