Аннотация: A computer model was developed and a study of the cold rolling modes of 1580 alloy sheets was carried out. The model provided for the achievement of the maximum total degree of reduction in cold rolling of 60% in the minimum number of passes, the rolling force should not exceed 90% of the maximum allowable for the rolling mill, and the Cockcroft-Latham criterion was not reach value 1, so that cracks do not occur along the edges of the rolled products. The simulation results were tested on a billet cut from a large-sized ingot cast at an industrial enterprise by the method of semi-continuous casting. Hot rolling was carried out on a two-roll mill with a roll diameter of 330 mm and a barrel length of 520 mm. For cold rolling a two-roll mill with a roll diameter of 200 mm and a barrel length of 400 mm was used. Based on the simulation results, cold rolling was carried out, as a result of which a 2-mm-thick strip without cracks along the edges was obtained from a hot-rolled billet 5-mm-thick in 8 passes. At the same time in all passes, the rolling force values did not exceed 90% of the allowable for the rolling mill, and the Cockcroft-Latham criterion was less than 1. Thus, it is shown that computer modeling allows to optimize the rolling route of thin sheets of alloy 1580 and to carry out cold rolling with a total reduction rate of 60% for a minimum number of passes to obtain high-quality sheet semi-finished products. © 2021, The Author(s), under exclusive licence to Springer-Verlag London Ltd. part of Springer Nature.
