摘要
A two-dimensional axisymmetric finite element model for stress distribution of billet in electromagnetic soft-contact continuous casting mould was established by a two-way coupled method.The contact state between solidified shell and mould was described to simulate the thermal-mechanical behaviors in the soft-contact mould.And the effects of frequencies and currents on stress distribution of billet had been discussed and analyzed.The results show that the equivalent stress of initial solidification shell both at its outer and inner surface decreases but at the bottom the equivalent stress of two sides of shell both increases when the current intensity is 1600 A,and the frequency is 20 kHz,compared with the status of conventional continuous casting.
