摘要
以实测结晶器铜板温度计算的热流量作边界条件,采用有限元方法,建立了结晶器内凝固传热方程,对凝固传热方程进行了离散化,利用ANSYS商业软件进行求解,得到凝固坯壳的应力、应变情况,从而确定连铸结晶器壁的合理锥度。
A mathematical model was proposed to calculate the stress distribution of the solidification shell in a slab mold based on the local heat flux calculated by using the measured temperature of the copper plate. Solidification equations to liquid steel were built and discreted by the finite element method. ANSYS commercial software was used to solve these discrete equations, the stress and strain distributions were obtained and the taper of the mold was decided according to these calculating results.
