Abstract. The rolling process of Z-shaped asymmetric profile is presented on example of spine beam profile of railway carriages is simulation. Based on simulation results, a high polarity created from rolls was revealed, which leads to increased strip twisting. According results obtained, roll pass redesign with reductions redistribution was carried out. As result, there is a decrease in different polarity when modeling process using a modified roll pass design. Experimental rolling showed a positive result with decrease in strip twisting and maintaining required profile geometry.
