The quality of a steel charge heating and the load of the annular bottom of a rotating hearth furnace

Providing a correct thermal regime the consumption of heat is reduced as well as the loss of steel because of its surface oxidation. Using the data about the steel charge and the furnace working space geometry and particular requests in connection with the temperature of the charge and the decrease of the rotating hearth furnace heating capacity, the temperature of gases combustion and the inside walls surface along the working space of the furnace are defined by a calculating method. Calculated parameters are used as the initial parameters for the charge heating in working conditions. The steel oxidizing loss as well as the influence of the oxidizing loss on the total heat consumption in the furnace are defined by a calculating method and by direct measuring too. Having the insight of the steel oxidizing loss is a presumption for a more complete heating control as to ensure high quality products of a seamless pipes rolling mill.
