Claims (5)

1. Способ получения отливок направленной кристаллизацией, включающий нагрев керамической формы до заданной температуры, расплавление и заливку жаропрочного сплава из плавильного тигля в керамическую форму и последующую направленную кристаллизацию путем опускания керамической формы с расплавом из зоны нагрева в зону охлаждения, отличающийся тем, что заливку жаропрочного сплава в керамическую форму осуществляют через заливочную чашу, имеющую в донной части не менее двух отверстий или каналов, обеспечивающих капельную, регулируемую интенсивность подачи расплава на фронт кристаллизации, а процесс направленной кристаллизации начинают после заполнения расплавом 2-9% объема керамической формы.1. A method for producing castings by directional crystallization, including heating a ceramic mold to a predetermined temperature, melting and pouring a heat-resistant alloy from a melting crucible into a ceramic mold and subsequent directed crystallization by lowering a ceramic mold with a melt from the heating zone into the cooling zone, characterized in that the casting is heat-resistant alloy in a ceramic form is carried out through a pouring bowl having in the bottom of at least two holes or channels providing a drip, adjustable in ensivnost melt feed at the crystallization front, and a process of directional solidification beginning to melt after filling of 2-9% of the ceramic mold. 2.

A device for producing directional crystallization castings, containing a vacuum chamber inside which a ceramic mold heating furnace is placed, a crucible for melting a heat-resistant alloy, a ceramic mold, a mechanism for moving the mold from the heating zone to the cooling zone, a mold, characterized in that the ceramic mold is equipped with a casting a bowl with holes or channels in its bottom. 3. Устройство по п. 2, отличающееся тем, что отверстия или каналы выполнены в пластине, установленной в донной части заливочной чаши. 3. The device according to p. 2, characterized in that the holes or channels are made in the plate installed in the bottom of the pouring bowl. 4. Устройство по п. 3, отличающееся тем, что пластина выполнена из материала, инертного к расплаву жаропрочного сплава. 4. The device according to p. 3, characterized in that the plate is made of a material inert to the heat-resistant alloy melt. 5. Устройство по п. 2, отличающееся тем, что заливочная чаша содержит не менее двух отверстий или каналов, расположенных на расстоянии друг от друга в соответствии с сечением профиля отливки. 5. The device according to p. 2, characterized in that the pouring bowl contains at least two holes or channels located at a distance from each other in accordance with the cross section of the casting profile.
