This paper presents the results of research on the determination of the influence of kinetic asymmetry of work rolls on structural changes in hot-rolled bimetallic sheet metals. The tests were conducted on bimetallic samples composed of materials 10CrMo9-10 + X2CrNiMo17-12-2. The scope of the research included a comparative analysis for two cooling variants: I in water (freezing the structure immediately after rolling) and II for cooling in air. The research conducted showed that the introduction of asymmetric conditions to the rolling process results in a greater grain fragmentation in the so-called hard layer and does not have a negative effect on microstructural changes in the soft layer.
本文介绍了关于确定工作辊动力学不对称性对热轧双金属板材结构变化影响的研究结果。试验是在由10CrMo9-10 + X2CrNiMo17-12-2材料组成的双金属样品上进行的。研究范围包括对两种冷却方式的对比分析：方式I为在水中冷却（轧制后立即使组织冻结），方式II为在空气中冷却。所进行的研究表明，在轧制过程中引入不对称条件会导致所谓硬层中更大程度的晶粒破碎，并且对软层的微观结构变化没有负面影响。
