摘　　要：利用特厚规格复合板与较薄规格复合板进行非对称组坯,采用ABAQUS有限元软件对其热轧过程中的应变、接触应力及温度分布进行计算,并通过温度补偿及冷却控制的手段,对热轧非对称复合坯的可行性进行模拟分析。结果表明,采用非对称组坯设计,有利于特厚复合板碳钢层与不锈钢层在各道次轧制中的界面结合;通过控制复合坯上、下表面的温差,能有效改善板坯翘曲现象,并可一次性获得一块宽幅特厚复合板与一块宽幅较薄规格复合板,提高生产效率;此外,采用非对称组坯设计还可实现控轧控冷,保证芯部不锈钢与碳钢的协同变形,促进其界面结合。In this paper,an extra-thick clad steel plate and a thin clad steel plate were asymmetrically assembled,and the strains,contact stresses and temperature distributions of assembly during the hot rolling process were calculated by ABAQUS finite software.Through temperature compensation and cooling control,the feasibility of hot rolling asymmetrically assembled clad steel plates was also investigated by numerical simulation.The results show that asymmetrical assembly design is beneficial to the interfacial bonding between carbon steel layer and stainless steel layer of the extra-thick clad plate during each rolling pass.By controlling the temperature difference between upper and lower surface,the slab warping phenomenon can be effectively improved,and both a thin and an-extra thick stainless clad steel plates can be obtained at the same time,thus improving the production efficiency.Moreover,asymmetrical assembly design also enables the control of rolling and cooling,and therefore ensures the cooperative deformation of stainless steel and carbon steel in the core section and promotes its interfical bonding as a consequence.
