针对中厚板在高密度管流控制冷却过程中温度场的变化情况,利用ANSYS有限元分析软件进行了分析,建立了比较合理的温度场的有限元模型,并获得不同规格奥氏体不锈钢板(0Cr18Ni9)在各种条件下的温降曲线和瞬态温度场分布,同时,对钢板控冷过程中表面与心部的温差进行了优化,使钢板表面与心部温差的最大值从580℃下降到500℃,为进一步提高钢板的性能与质量提供了理论依据。
Aiming at the change of temperature field of plate in high density flow control cooling process, the finite element analysis software ANSYS was used to analyze and establish a more reasonable finite element model of temperature field, and obtain different specifications of austenitic stainless steel plate (0Cr18Ni9) under various conditions, the temperature drop curve and the transient temperature field distribution. Meanwhile, the temperature difference between the surface and the heart during the controlled cooling of the steel plate is optimized so that the maximum temperature difference between the surface of the steel plate and the core is from 580 ℃ Down to 500 ℃, in order to further improve the performance and quality of steel provides a theoretical basis.
