Calculation of Heat Loss of Furnace Body in Electric Arc Furnace Steelmaking

The heat loss of furnace body in EAF steelmaking process is large and difficult to quantify, which affects the accurate control of smelting end temperature. In this paper, the EAF body is divided into four parts, namely the upper shell, the lower shell, the bottom of the furnace, and the furnace cover. The heat transfer in different regions is studied to explore the characteristics of radiation heat transfer and convection heat transfer between the EAF body and the surrounding environment. A theoretical calculation method of heat loss in EAF steelmaking process is obtained, which provides a theoretical basis for energy saving and emission reduction of EAF steelmaking.
