考虑铜板结构和铸坯凝固特性,以二者接触区域为纽带,建立温度场和应力场高度耦合的有限元分析模型,通过耦合计算,发现板坯在连铸结晶器中宽窄面方向上的坯壳表面温度、坯壳生长行为及界面气隙状态沿拉坯方向上的变化规律,为分析和解决铸坯在结晶器中产生的质量问题、设计或优化有漏钢预报测温热电偶布置提供了理论依据。 Considering the structure of the copper plate and the solidification characteristics of the billet, a finite element analysis model was established which was highly coupled with the temperature field and the stress field by using the contact area as the link. Through the coupling calculation, it was found that the slab Shell surface temperature, growth behavior of blank shell and interface air gap along the direction of blank drawing, in order to analyze and solve the quality problems of slab in mold, to design or optimize the configuration of thermocouple with breakout forecast and temperature measurement The theoretical basis.
