Энергосиловые параметры и значение кривизны полосы характерны для асимметрического процесса прокатки

Abstract

The paper presents theoretical analysis of asymmetrical plate rolling process with initial strip thickness (200, 150, 100, 80, 70) mm conducted in the plate preliminary mill 3600. The purpose of the work was to determine the influence of putting angle of the pass into the deformation zone and working rolls velocity asymmetry on the value of rolling force and direction of the bending radius of strip flowing out from the deformation zone. The variable parameters of the process were: putting angle of the pass θ; rotational speed asymmetry factor, av = vd/vg. From the investigation carried out within the work it was found that the most representative data obtained during asymmetric plate rolling process with rolling reduction of ε = 0,20 which was put into this paper work.
