Изобретение направлено на изготовление непрерывнолитых полых изделий с практически любой толщиной стенки, повышение качества поверхности и внутренней структуры, получение полых заготовок с размерами близкими к готовым изделиям, увеличение скорости разливки металла. Это обеспечивается заливкой металла в пространство между стенками кристаллизатора и установленным в нем стержнем, периодическом разрушении сформированной корочки с одновременным обжатием на наклонных гранях кристаллизатора и центральном стержне жидкого металла в количестве 20-40% и твердого металла в количестве 60-80% от объема металла, выдаваемого в пространство между гранями и центральным стержнем. При этом кристаллизатор выполнен с двумя вертикальными, совершающими возвратно-поступательное движение и двумя наклонными в верхней части гранями, совершающими вращательное движение. В устройстве для получения непрерывнолитых полых заготовок, содержащем разливочную емкость с дозирующим устройством и насадками, водоохлаждаемый кристаллизатор с четырьмя гранями и центральный стержень, выполненный с конической верхней и калибровочной нижней зонами, верхняя часть центрального стержня выполнена в виде тепловой трубы с углом наклона конической части α = 3÷7°.The invention is directed to the manufacture of continuously cast hollow articles with virtually any wall thickness, improving the quality of the surface and internal structure, obtaining hollow billets with dimensions close to the finished products, increasing the speed of metal casting. This is ensured by pouring the metal into the space between the walls of the mold and the rod installed in it, periodically destroying the crust formed with simultaneous compression on the inclined faces of the mold and the central core of the liquid metal in the amount of 20-40% and solid metal in the amount of 60-80% of the metal volume, issued in the space between the faces and the central core. In this case, the mold is made with two vertical, reciprocating and two inclined in the upper part of the edges, making a rotational motion. In the device for the production of continuously cast hollow billets, containing a casting tank with a metering device and nozzles, a water-cooled mold with four edges and a central rod made with a conical upper and calibration bottom zones, the upper part of the central rod is made in the form of a heat pipe with an angle of inclination of the conical part α = 3 ÷ 7 ° .
