Abstract
1. Способ получения непрерывнолитых полых заготовок, включающий подачу жидкого металла в пространство между гранями кристаллизатора и установленным в нем центральным стержнем, формирование корочки на гранях кристаллизатора и стержне, калибровку внутренней поверхности полой заготовки и ее выталкивание из кристаллизатора, отличающийся тем, что кристаллизатор выполняют с двумя вертикальными, совершающими возвратно-поступательное движение, и двумя наклонными в верхней части, совершающими вращательное движение, гранями, при этом сформированную корочку периодически разрушают с одновременным обжатием на наклонных гранях кристаллизатора и центральном стержне жидкого металла в количестве 20 - 40% и твердого металла в количестве 60 - 80 об.% металла, подаваемого в пространство между гранями и центральным стержнем.2. Устройство для получения непрерывнолитых полых заготовок, содержащее разливочную емкость с дозирующим устройством, водоохлаждаемый кристаллизатор и установленный в нем центральный стержень, выполненный с конической верхней и калибровочной нижней зонами, отличающееся тем, что кристаллизатор выполнен с двумя вертикальными гранями, имеющими возможность возвратно-поступательного движения, и двумя гранями, выполненными наклонными в верхней части и с возможностью вращательного движения, при этом верхняя часть центрального стержня выполнена в виде тепловой трубы с углом наклона конической зоны 3 - 7.1. A method for producing continuously cast hollow billets, including feeding liquid metal into the space between the faces of the mold and the central rod installed in it, forming a crust on the faces of the mold and the rod, calibrating the inner surface of the hollow billet and pushing it out of the mold, characterized in that the mold is performed with two vertical, reciprocating, and two inclined in the upper part, performing a rotational movement, faces, while the formed crust is periodically destroyed with simultaneous compression on the inclined faces of the mold and the central rod of liquid metal in an amount of 20 - 40% and solid metal in the amount of 60 - 80 vol.% of the metal fed into the space between the edges and the central rod. 2. A device for producing continuously cast hollow billets, containing a pouring vessel with a metering device, a water-cooled crystallizer and a central rod installed in it, made with a conical upper and calibrating lower zones, characterized in that the crystallizer is made with two vertical edges capable of reciprocating movement, and two faces made inclined in the upper part and with the possibility of rotational movement, while the upper part of the central rod is made in the form of a heat pipe with an inclination angle of the conical zone 3 - 7.
