| Abstract: | The exchange heat boundary conditions of an accelerated controlled-cooling system (ACC) were decided, and a finite element model of temperature and stress field was constructed. The calculated result of temperature field was proved by testing data, and the stress field of steel plates was computed by using the coupling method. Finally, the effects of parameters such as header combination, running speed and cooling medium temperature on the heat residual stress were analyzed. |
