摘要

A numerical program has been developed and applied to investigate the heating characteristics of the slab in a bench scale reheating furnace. Its numerical results were validated by comparison with the experimental data obtained in the test facility installed in POSCO company. The corners of the slab are heated faster than any other regions because they have larger thermal resistivity than the other regions - edges and flat plain surfaces. The temperature difference between a corner point considered and inner slab point increase until a certain instant, but after then it continuously decrease by action of inward conduction. Maximum temperature difference between the corner point and inner slab is 419℃ at 210 s for 0.5 m slab location and 264℃ at 550 s for 4.0 m slab location.
