Abstract：The temperature of continuous casting billet is the key to the successful implementation of the continuous casting direct rolling process. In order to solve the problem of the connection between the temperature and speed of the continuous casting billet in the continuous casting direct rolling process, the temperature change of the continuous casting billet and the thickness of the solid shell in the whole process from the meniscus of the mold to the front of the rolling mill were simulated by ANSYS software. On this basis, the influences of the processing parameters, such as the casting speed, casting temperatures and specific water volume on the billet temperature, the thickness of the solid shell and the position of solidification terminal were analyzed. The results showed that under the conditions of the casting speed of 2.8 m/min, casting temperature of 1 550 ℃ and specific water volume of 1.4 L/kg, the average temperature of the billet before reaching the rolling mill can still remain more than 900 ℃, which can meet the requirements of direct rolling process. The research results would be beneficial to the connection between continuous casting and rolling, and provide useful reference for the transformation of continuous casting workshop in steel plants.
