利用有限元分析软件建立了带钢热连轧过程的热力耦合综合有限元模型,对于试算的CSP流程沿带钢厚度方向上等效塑性应变呈“V”形或“U”形分布,轧制过程有限元模型预测的轧制力与实际吻合较好;适量增加铸坯厚度,并在较靠前的机架分配较大的压下量有利于提高轧制过程的应变均匀性。依托组织性能预报技术集成了较适合于含铌微合金化钢的组织演变模型,利用集成系统的多次试算提出了CSP生产X60管线钢的较优工艺。
The finite element analysis software is used to establish the coupled thermo-mechanical finite element model of the hot strip rolling process. The equivalent plastic strain in the strip thickness direction of the trial CSP is “V” or “U” The rolling forces predicted by the finite element model of the shape distribution and the rolling process are in good agreement with the actual ones. Increasing the slab thickness by a proper amount and allocating a larger reduction in the forward racks are helpful to improve the strain uniformity during the rolling process Sex. Relying on the organization of performance prediction technology integrated more suitable for the micro-alloyed niobium-containing steel microstructure evolution model, the use of integrated system of several trial calculations X60 Pipeline CSP production of better technology.
