| Summary: | The thermal stress coupling calculation model of initial shell in groove mold is established for temperature field and stress field calculation. The calculated results show that groove mold can improve heat transfer of casting initial shell and form peaks and valleys of temperature and stress, and the whole curve corresponding to overall number of grooves. The surface temperature of initial shell increase with the width of grooves increase, the non-uniformity of initial shell surface temperature and stress also increases. The surface temperature of initial shell decrease with the space of grooves increase, the non-uniformity of surface temperature and surface stress of initial shell increases. Groove depth has a little influence on heat transfer of initial shell surface. |
