Abstract：

Based on the temperature situation during the rolling process of 4200 mm/3500 mm medium and thick plates at Baosteel, this article analyzes the influencing factors of temperature changes during the rolling process from the perspective of heat transfer theory and the temperature change law during the rolling process. The temperature loss during the four rolling processes is tracked on site, and the temperature drop model parameters during the rolling process of 4200mm/3500mm medium and thick plates at Baosteel are quantitatively provided. It is applied to actual rolling production and has achieved good results.

Key Words：
