Abstract

1. Устройство для получения отливок направленной кристаллизацией, содержащее герметичную камеру нагрева, в которой установлены поворотная индукционная плавильная печь, закрепленная на боковой крышке камеры, и печь нагрева формы, расположенная ниже плавильной печи, камеру охлаждения с узлом охлаждения формы в виде водоохлаждаемой емкости, изоляционный клапан, расположенный между камерой нагрева и камерой охлаждения, механизм вертикального перемещения формы, содержащий шток, проходящий через вакуумное подвижное уплотнение в нижней стенке камеры охлаждения, поддон с охлаждаемой полостью, установленный на верхнем торце штока, механизм фиксации формы в печи нагрева, шлюзовую камеру для загрузки шихты в тигель индукционной плавильной печи, отличающееся тем, что оно снабжено вакуумной камерой привода штока, расположенной ниже камеры охлаждения, приводом поворота поддона вокруг вертикальной оси штока, включающим прикрепленную к поддону снизу поворотную трубу с квадратным отверстием, расположенную с зазором в отверстии штока, квадратный вал, размещенный внутри трубы с зазором, и механизм поворота квадратного вала вокруг вертикальной оси, расположенный в нижней части вакуумной камеры привода штока, блоком подвижных отражательных экранов, расположенных в верхней зоне узла охлаждения формы, при этом механизм фиксации формы выполнен в виде шлицевого диска, расположенного на охлаждаемом поддоне соосно с ним, и кольцевой шлицевой опоры, закрепленной в нижней части печи нагрева и имеющей пазы с размерами, обеспечивающими взаимодействие с выступами шлицевого диска при подъеме штока с формой в печь нагрева форм�1. A device for producing castings by directional crystallization, containing a sealed heating chamber, in which a rotary induction melting furnace is installed, mounted on the side cover of the chamber, and a mold heating furnace located below the melting furnace, a cooling chamber with a mold cooling unit in the form of a water-cooled container, insulating a valve located between the heating chamber and the cooling chamber, a mechanism for vertical movement of the form, containing a rod passing through a vacuum movable seal in the lower st nk cooling chamber, a pan with a cooled cavity mounted on the upper end of the rod, the mechanism for fixing the form in the heating furnace, a lock chamber for loading the charge into the crucible of an induction melting furnace, characterized in that it is equipped with a vacuum chamber of the rod drive located below the cooling chamber, the drive rotation of the pallet around the vertical axis of the rod, including a rotary tube with a square hole attached to the bottom of the pallet, located with a gap in the rod hole, a square shaft located inside the pipe with a gap orom, and the mechanism of rotation of the square shaft around the vertical axis, located in the lower part of the vacuum chamber of the rod drive, by a block of movable reflective screens located in the upper zone of the mold cooling unit, while the form fixing mechanism is made in the form of a spline disk located coaxially with the cooling pan him, and an annular spline support, fixed in the lower part of the heating furnace and having grooves with dimensions that ensure interaction with the protrusions of the spline disk when lifting the rod with the mold into the mold heating furnace
