| Abstract: | Based on the plate theory, the solution of the solidified shell deflection in the static pressure of molten steel and temperature field under the joint action is derived while taking into account the high-temperature creep deformation. Based on the energy method of bulging deformation, an analytical model of the casting withdrawal resistance is deduced. The accuracy of calculating maximum bulging deformation and casting withdrawal resistance is analyzed by project examples and actual measured results. |

| Keywords: | continuous casting bulging deformation withdrawal resistance of casting |
