Abstract
Способ продольного разделения проката, включающий нагрев металла, предварительное формирование состоящего из нескольких соединенных между собой перемычкой частей профиля и разделение полученного профиля на части разрушением соединительной перемычки неприводным делительным устройством, отличающийся тем, что неприводное делительное устройство устанавливают на расстоянии, не превышающем межосевое расстояние между валками, формирующими сочлененный профиль, и роликами неприводного делительного устройства, которое определяют по следующей зависимости ! , ! при σp≤σs, ! где lmax - максимальное межосевое расстояние между валками, формирующими сочлененный профиль, и роликами неприводного делительного устройства, мм; ! Е - модуль упругости материала разделяемой полосы, МПа; ! - минимальный радиус инерции, мм2; ! σp - напряжение подпора, необходимое для продольного разделения, МПа; ! k - коэффициент приведения длины; ! σs - фактическое сопротивление деформации разделяемого материала, МПа.A method of longitudinal separation of rolled metal, including heating the metal, pre-forming a profile part consisting of several interconnected by a jumper and dividing the obtained profile into parts by destroying the connecting jumper by an non-drive dividing device, characterized in that the non-drive dividing device is installed at a distance not exceeding the center distance between the rollers forming an articulated profile and rollers of a non-power dividing device, which is determined by the trace addiction! ! for σp≤σs,! where lmax is the maximum center distance between the rolls forming an articulated profile and the rollers of a non-driven dividing device, mm; ! E is the modulus of elasticity of the material of the shared strip, MPa; ! - minimum radius of inertia, mm2; ! σp is the back pressure required for longitudinal separation, MPa; ! k is the coefficient of reduction of length; ! σs is the actual deformation resistance of the shared material, MPa.
