Claims (3)

1. Устройство для получения отливок с направленной и монокристаллической структурой, включающее вакуумную камеру, внутри которой расположена печь подогрева форм с размещенной в ней керамической формой с вертикальным экраном, и кристаллизатор, отличающееся тем, что вертикальный экран выполнен отдельно от керамической формы и установлен концентрично вертикальной оси отливки, при этом нижний торец его открыт в сторону кристаллизатора.1. A device for producing castings with directional and single-crystal structure, including a vacuum chamber, inside which there is a mold heating furnace with a ceramic mold with a vertical screen placed in it, and a mold, characterized in that the vertical screen is made separately from the ceramic mold and installed concentrically vertical the axis of the casting, while its lower end is open towards the mold. 2. Устройство по п.1, отличающееся тем, что экран выполнен в виде элементов, телескопически складывающихся в процессе направленной кристаллизации. 2. The device according to claim 1, characterized in that the screen is made in the form of elements that are telescopically folding in the process of directional crystallization. 3. Устройство по п.1, отличающееся тем, что экран выполнен из теплоизоляционного материала, например графитированной фольги или композиционного материала на основе углерод-углерод. 3. The device according to claim 1, characterized in that the screen is made of heat-insulating material, such as graphite foil or carbon-carbon-based composite material.
