Abstract

1. Способ изготовления литых труб большого диаметра, включающий производство полосы, последующую формовку и соединение противоположных боковых граней полосы по винтовой линии, отличающийся тем, что, с целью снижения затрат при производстве труб большого диаметра, полосу производят непрерывным литьем металла в криволинейный кристаллизатор, после выхода из кристаллизатора полосу изгибают по радиусу изготавливаемой трубы с учетом температурной усадки, после чего передний конец полосы вводят в кристаллизатор, стыкуя боковые грани вводимой и кристаллизующейся полос, при этом отводят подвижную боковую стенку кристаллизатора в направлении и со скоростью литья полосы.2. Способ по п.1, отличающийся тем, что, с целью повышения качества зоны стыка соединяемых участков трубы, производят зачистку боковой кромки вводимой в кристаллизатор полосы на глубину 0,1 - 5,0 мм.3. Устройство для изготовления литых труб большого диаметра, содержащее криволинейный кристаллизатор, рабочая полость которого выполнена из охлаждаемых стенок, и направляющие ролики, отличающееся тем, что, с целью обеспечения получения трубы путем ввода в кристаллизатор ранее отлитой в нем полосы, рабочая полость кристаллизатора выполнена по форме участка винтовой полосы, при этом одна боковая стенка кристаллизатора установлена подвижно.1. A method of manufacturing cast pipes of large diameter, including the production of the strip, the subsequent molding and connection of the opposite side faces of the strip along a helical line, characterized in that, in order to reduce costs in the manufacture of large diameter pipes, the strip is produced by continuous casting of metal into a curvilinear crystallizer, after leaving the mold, the strip is bent along the radius of the pipe being manufactured, taking into account the temperature shrinkage, after which the front end of the strip is introduced into the crystallizer, joining the side faces minutes and crystallizing bands, wherein the movable side wall is withdrawn in the direction of the mold and with the casting speed polosy.2. The method according to claim 1, characterized in that, in order to improve the quality of the joint zone of the connected pipe sections, the side edge of the strip introduced into the mold to a depth of 0.1-5.0 mm is scraped. A device for the manufacture of cast pipes of large diameter, containing a curvilinear mold, the working cavity of which is made of cooled walls, and guide rollers, characterized in that, in order to ensure that the pipe is obtained by introducing into the mold of a strip previously cast in it, the working cavity of the mold is shaped section of the screw strip, while one side wall of the mold is installed movably.
