Abstract

The invention discloses liquid metal cooling and directional condensing equipment with a tin boiler stirrer, which comprises a mould heating and insulating furnace, a ceramic mould, a chilling tray, a drawing bracket, a container, a floating insulation baffle, a first stirrer, a second stirrer and a stirrer drive mechanism, wherein an upper heating area and a lower heating area are reserved in the mould heating and insulating furnace, the ceramic mould is arranged in the mould heating and insulating furnace, and the chilling tray is connected with the ceramic mould and driven by the drawing bracket to move up and down; the container is arranged below the mould heating and insulating furnace and filled with liquid metal tin, and the floating insulation baffle is arranged on the liquid surface of the liquid metal tin; and the first and second stirrers capable of rising and descending are symmetrically arranged in the container. The liquid metal cooling and directional condensing equipment with the tin boiler stirrer solves the problem of overflowing of the liquid metal tin and prevents the liquid surface of the liquid metal tin from rising and contacting the heating furnace; and due to vertical movement of the stirrers, the heat exchange of the liquid metal tin is speeded up, so that the temperature of the liquid metal tin is uniform.

Description

technical field

[0001] The invention relates to a liquid metal cooling directional solidification device with a tin pot stirring device, in particular to a tin pot stirring device suitable for the directional solidification device for manufacturing large-scale gas turbine column crystal blades. Background technique

[0002] Due to the development of aviation, aerospace and ground gas turbine power generation technology, the temperature of the gas inlet before the turbine of the power mechanical gas turbine used in these fields is continuously increasing, which requires the temperature resistance of the turbine blades to continuously increase. The directional and single crystal blades eliminate the transverse grain boundary perpendicular to the stress axis, and the grain direction is parallel to the stress direction acting on the blade, which cuts off the root cause of failure occurring at the grain boundary perpendicular to the stress direction, and the temperature resistance...
