【摘要】 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。更多还原

【Abstract】 This paper aims at the changes of the temperature field in the accelerated cooling process of the heavy plate,the logical temperature field FEM model of the heavy plate in the process of the high denseness pipe laminar flow accelerated cooling was built in ANSYS software,and temperature-drop curve and transient temperature field distributing of austenitic stainless steel under the various kinds of conditions was gained,the difference in temperature between the exterior and the center in the process of controlling cooling was optimized,the maximum of the difference in temperature between the exterior and the center drop from 580℃ to 500℃,which offer the theoretical foundation to the more improvement of the quality and the capability of the heavy plate.更多还原
