description In order to solve the problems of strip break and strip bulging in the commissioning process of thin strip continuous casting industrial production line and improve the solidification structure and surface quality of thin strip continuous casting, an unsteady model of the twin roll strip continuous casting process was established based on the finite element software ProCAST. The temperature field and solidification structure of Q195 solidification process were simulated, and the single variable method was used to study the effects of different process parameters, including casting temperature, drawing speed, heat transfer coefficient and molten pool height, on the temperature field and solidification structure of the solidification process. The results show that the optimal parameters in the twin roll strip continuous casting process of Q195 steel under the existing working conditions are as follows: casting temperature of 1 590 ℃, casting speed of 10 m/s, heat transfer coefficient of 2 000 W/(m2</sup>·K), and molten pool height of 188 mm, which can effectively prevent strip break and strip bulging, and can achieve the goal of refining grains and improving the quality of thin strip billets. It is of great significance to study the variation of temperature field, solidification structure and stress field in the process of strip solidification for improving the quality of strip and promoting the localization of strip casting and rolling process.
