Abstract
Способ получения отливки лопатки газовой турбины с направленной и монокристаллической структурой, включающий вертикальное перемещение в вакуумной установке из зоны нагрева в зону охлаждения оболочковой керамической формы с кристаллизующимся расплавом и ее охлаждение потоками инертного газа из сопел, направленных на форму в верхней части зоны охлаждения, отличающийся тем, что охлаждение формы потоком инертного газа из сопел ведут на расстоянии 40-70 мм от верхнего среза зоны охлаждения при давлении газа в критическом сечении сопла 3-10 бар, остаточном давлении инертного газа в зоне охлаждения 100-300 мбар и скорости перемещения формы 5-10 мм/мин.A method of producing a casting of a gas turbine blade with a directional and single-crystal structure, including vertical movement in a vacuum installation from the heating zone to the cooling zone of a shell ceramic mold with crystallizing melt and its cooling by inert gas flows from nozzles directed to the mold in the upper part of the cooling zone, characterized in that the mold is cooled by a stream of inert gas from the nozzles at a distance of 40-70 mm from the upper cut of the cooling zone at a gas pressure in the critical section of the nozzle of 3-10 ba p, the residual inert gas pressure in the cooling zone of 100-300 mbar and the speed of movement of the form 5-10 mm / min
