Abstract: To make sure that the billet/bloom temperature meet the rolling requirement so as to provide quality steel sections, the temperature distribution in reheating furnace is of crucial importance. With the intermittent reheating furnace using natural gas as fuel exemplified, the transient 3D distribution of temperature fields in the furnace and heated billet/bloom are analyzed introducing CFD(computational fluid dynamics), i.e., the software Fluent is used to simulate the temperature distribution in furnace under different operating conditions, thus providing theoretically a reference for improving the efficiency of reheating furnace. In the simulation the heat loss due to furnace door opening for billet/bloom discharging and charging is taken into account. The simulation results are available to optimize the operating parameters so as to improve the quality of finished paroducts.
