This paper carries out a twodimensional unsteady heat conduction model of Billet. Based on this model the effective length of regenerative reheating furnace is analyzed. Compared with engineering data, the model's calculation results are correct and reliable. The model, as well as the relevant reference length for regenerative furnace, is helpful to the design of regenerative reheating furance, especially to the calculation of the effective length of furnace.
