【Abstract】 In the paper the mathematical model of solidification and heat transfer in mould is built. The temperature field of billet,shell thickness, heat flow field, heat shrinkage stress field of billet shell,gap thickness between billet shell and copper wall of mould are analogously computed. The computed thickness of billet shell basically tallies with measured thickness. The computed result is available for reference for design and production of continuous caster.更多还原
