Abstract
1. Способ прокатки профилей корытной формы, преимущественно типа железнодорожных двухголовых накладок, включающий многопроходное обжатие нагретой заготовки в валках с калибрами, отличающийся тем, что для изготовления профилей корытной формы используют заготовку круглого сечения, формирование профиля осуществляют в калибрах открытого типа с заведомо увеличенной шириной профиля, при этом, окончательное формирование профиля производят в ребровом калибре путем обжатия раската в холодном состоянии. ! 2. Система калибров для осуществления способа прокатки профилей корытной формы, содержащая последовательно расположенные калибры стана горячей прокатки, а именно, черновой, промежуточный, предчистовой и чистовой калибры, отличающаяся тем, что черновой калибр выполнен с одним разрезающим нижним гребнем, предчистовой калибр выполнен вертикальным, чистовой калибр имеет выпуски с уменьшенными радиусами скругления, кроме того, система калибров дополнительно содержит горизонтальный ребровой калибр стана холодной прокатки, при этом все калибры выполнены открытыми.1. A method of rolling profiles of a trough shape, mainly of the type of two-headed rail linings, including multi-pass compression of a heated billet in rolls with calibers, characterized in that a round billet is used to produce trough profiles, the profile is formed in open gauges with a deliberately increased profile width at the same time, the final formation of the profile is performed in the rib caliber by compressing the roll in the cold state. ! 2. A gauge system for implementing the method of rolling trough shaped profiles, comprising successively arranged calibers of the hot rolling mill, namely, a draft, intermediate, finish and finish gauge, characterized in that the draft gauge is made with one cutting lower ridge, the finish gauge is made vertical, the finishing gauge has outlets with reduced rounding radii, in addition, the gauge system additionally contains a horizontal rib gauge of the cold rolling mill, while all cal bry made public.
