摘要
利用有限元模拟技术,建立了钢板冷却过程的热、力和组织耦合的有限元模型,计算了在控冷输出辊道上3种不同冷却模式下的温度场、应力场和组织场。分析表明,采用稀疏冷却方式能提高厚度方向上的冷却均匀性;上下表面冷却均匀有利于减小钢板的翘曲;采用不同冷却路径可获得不同的组织和性能。其分析可为中厚钢板控冷获得理想的板形、组织和性能提供理论依据。
A coupling thermal, mechanical and microstructure finite element model had been developed by using FEM simulation technique. The results of temperature, stress and microstructure were calculated about three kinds of cool- ing pattern on the runout table. The simulation results showed that sparse cooling could improve the temperature uni- form in depth, the wrap deflection could be decreased by the even cooling on the upper and down surface, the micro- structures and properties could be controlled under different cooling routes. The result offered theoretical basis for ideal shape, microstructure and properties.
