Problems solved by technology

However, the temperature of the chilling plate fluctuates greatly. For example, when the heat preservation temperature of the mold is 1550°C and the depth of the chilling plate is immersed in the liquid metal is 5.08cm, the temperature of the chilling plate is 250°C to 550°C during the whole process, resulting in uneven cooling intensity. large temperature fluctuations

Embodiment

[0015] A chilling plate for cooling and directional solidification of liquid metal, comprising a chilling plate body 1, characterized in that the chilling plate body 1 has an annular channel 13 or a petal-shaped channel 12 for the liquid medium to pass through, the chilling plate body 1 Made of stainless steel or heat-resistant steel.

[0016] The principle of use of the liquid metal cooling directional solidification chiller of the present invention:

[0017] The chilling plate body 1 is fixed on the ceramic casting mold or the casting mold combination 5 with the bottom opening as the bottom of the casting mold to prevent the casting mold from breaking out. The most important thing is that the chilling plate body 1 can be cooled by liquid medium heat transfer oil, and the liquid medium heat transfer oil enters the chilling plate body 1 along the A direction through the inner hollow drawing shaft 2 and flows out along the B direction. In the directional solidification process...

Abstract

The invention discloses a chilling disc for cooling, orienting and solidifying a liquid metal, which comprises a chilling disc body. The chilling disc for cooling, orienting and solidifying the liquid metal is characterized in that the chilling disc body is internally provided with an annular passage or a petal passage through which a liquid medium passes; and the chilling disc body is made of stainless steel or heat-resistant steel. The invention has uniform intensity of cooling, is in favor of the stable growth of the solidification front of a high-temperature alloy solid-liquid interface and the temperature equalization of a cooling medium around a mold.

Description

technical field [0001] The invention relates to a chilling plate for cooling and directional solidification of liquid metal, in particular to a chilling plate which can be circulated and cooled by a liquid medium. technical background [0002] In addition to the alloy composition, the grain characteristics determine the performance of the superalloy. Orientation 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. The temperature resistance is significantly improved and has a more Good longitudinal mechanical properties, able to work for a long time in the harsh environment of high temperature gas. [0003] Oriented and single-crystal blades were fabricated by fixing the open-bottomed mold on a chill plate, which served as the bottom of the mold. When the liquid metal is poured in, the metal in contact with the cooling plate will nucleate and grow ...
