漏钢是连铸生产过程中最严重的故障之一;目前,现有的漏钢预报系统大都是根据热电偶所采集的有限温度数据给出温度随时间变化的二维曲线,而无法使操作人员了解非采集点区域的温度情况;文章介绍了结晶器温度场可视化系统的组成和实现方法；主要实验参数有浇注温度、热流密度、热传导系数、比热容、玲却水流量、结晶器进出水温差、拉坯速度等；通过分析结晶器铜板的传热原理,建立温度热传导模型,确定其边界条件；通过与实测温度值相比较,证明了温度场模型的有效性；根据温度场模型的计算结果,用虚拟仪器工具LabVIEW和有限元分析软件ANSYS开发了结晶器温度场可视化系统,作为漏钢预报系统的辅助判断手段和决策平台.%Breakout is one of the most serious breakdown in the continuous casting process. Currently, the existing breakout prediction systems, mostly based on the limited temperature data collected by the thermocouple, just show the two-dimensional curve of varying temperature, disabling the operators know about the exact temperature situation of the non -acquisition area. However, this article describes the components and implementation methods of the visulization system of the mold temperature field , establishing temperature heat conduction model and the boundary conditions by analyzing the heat transfer principles of the mould copper plate. The main experimental parameters involved in this paper include pouring temperature, density of heat flow rate, thermal-conductivity coefficient, specific heat capacity, cooling water flow, inlet and outlet water temperature difference of crystallizer and throwing .speed, etc. Moreover, compared with the measured temperature, it proves the validity of the temperature field model. According to the temperature field model calculations,with the visual instruments Lab VIEW and finite element software ANSYS a mould temperature field visualization system has been created already, which can be used as the auxiliary means of judgement and decision-making platform for the breakout prediction systems.
