中文摘要：
为改善特大断面连铸方坯热容量大、传热效率低等问题,基于结晶器传热学理论分析,提出复合式结晶器新技术。针对此结晶器,在保证铜板正常工作情况下,采用耦合方法,分析铜板、内冷却器的温度场及热应力分布。结果表明,铜板温度最高为230.8℃,热应力最大为261 MPa;内冷却器最高温度为406℃,应力为399 MPa,对内冷却器结构材料要求提高。该计算结果及方法可为结晶器铜板设计及工业应用提供参考。
英文摘要：
In order to improve the large heat capacity and low heat transfer efficiency of continuous casting,a new mould based on thermo-analysis was designed with an inner cooling mould.The temperature field and thermal stress of copper plate and inner cooling mould were analyzed by coupled method on the basis of ensuring the copper plate work regularly.The results show that the maximum temperature and thermal stress of copper plate and inner cooling mould reach 230.8 ℃,406 ℃,261 MPa,399MPa,respectively,which takes a higher requirement for the inner cooling mould material.The calculation results and methods can provide a reference to the mold copper plate design and industry application.
