摘要

针对板坯连铸结晶器铜板冷却水槽的结构优化,将三维传热模型应用于结晶器铜板导热过程,并采用有限元方法进行了模拟,计算并比较了水槽结构优化前后结晶器宽面铜板热面温度分布情况.结果表明:水槽结构优化后铜板螺栓处温度较优化前降低6℃,弯月面处温度降低10℃;优化前和优化后铜板在螺栓处和弯月面处的温度波动幅度分别为3、1. 5℃和8、2℃,水槽结构优化后铜板传热能力和冷却均匀性有明显提高.
        To optimize the cooling gullet structure of slab mold copper plate,a three-dimensional heat transfer model was developed to study the thermal process of the mold copper plate by using finite element method. Based on this,the hot face temperature distribution of the mold wide face copper plate before and after the optimization were calculated and compared. The results showed temperature of the copper plate at the locations of bolt and meniscus reduced 6 ℃and 10 ℃ after optimization than that of before optimization,respectively. Range of the temperature variation at the locations of bolt and meniscus before and after optimization are 3 ℃ and 1. 5 ℃,8 ℃ and 2 ℃,respectively. Ability of the heat transfer and cooling uniformity is improved significantly after the cooling structure optimization.
