Abstract：Regard of problems of the heating process of bearing steel in reheat furnace, the realistic heating process of bearing steel was tested by the black box. The thermocouple was implanted in the billet, the temperature recorder was placed in the water cooling and data was extracted again after reheating. By analyzing test data, discussing the heating curve change trend and combining the actual length of reheating furnace, the bearing steel heating prosess was optimized, and the banded structure was improved. The banded structure can be controlled below 1.0 grade．
