水平连铸结晶器内真实换热边界计算及传递模型
Calculation and Transfer Model of Real Heat Transfer Boundary in Horizontal Continuous Casting Mold
摘要
Abstract
A new model has been proposed to address the issues of low calculation efficiency and poor convergence in the fully coupled calculation of cooling water flow and heat transfer,and liquid metal heat transfer and solidification in continuous casting crystallizer.The current models exhibit low calculation accuracy when the real cooling intensity is only coupled with liquid metal heat transfer and solidification.The new model aims to model the flow-heat transfer of cooling water and the heat transfer and solidification process of liq-uid metal separately.The model was coupled in series based on the in-situ temperature field data transfer program via secondary devel-opment.The results show that the real cooling boundary condition calculated by the coupled flow field can replace the traditional boundary condition application method of uniform interface heat transfer coefficient.The new model can accurately simulate the size,orientation,and quantity of the grain of the billet while ensuring the calculation efficiency and accuracy of the model.The simulation re-sults are in good agreement with the experimental results.关键词
