摘要
根据合金化管铸铁冷却壁热态试验数据确定了合金化管铸铁冷却壁温度场数值模拟的边界条件,利用ANSYS软件、采用热-结构耦合的方法计算了高温状态下合金化管铸铁冷却壁内钢质冷却水管的变形,分析了气隙层和水管热变形对合金化管铸铁冷却壁寿命的影响,得出保证合金化管铸铁冷却壁长寿的最佳气隙层厚度和相应的最佳使用热负荷。
The thermal boundary condition of the cast iron cooling stave with surface alloyed steel pipe was used for numerical simulation of temperature field and commercial software ANSYS and the method of coupling heat-structure were used to calculate thermal deformation of steel pipe at high temperature, and analyze the influence of air gap and thermal deformation on the life of cooling stave. The optimal size of air gap and hot load to guarantee long life of cast iron cooling stave were obtained.
