Freeze casting device and method

Abstract

The invention provides a freeze casting device. The freeze casting device comprises a casting mold cooling chamber, a casting process cooling chamber, a deep-cooling treatment chamber, a transmission mechanism, cold quantity supply equipment and a control system. The casting mold cooling chamber, the casting process cooling chamber and the deep-cooling treatment chamber are sequentially arranged on one side of the transmission mechanism. The cold quantity supply equipment is connected with the casting mold cooling chamber, the casting process cooling chamber and the deep-cooling treatment chamber and used for supplying cold quantity to the casting mold cooling chamber, the casting process cooling chamber and the deep-cooling treatment chamber. The control system is connected with the casting mold cooling chamber, the casting process cooling chamber, the deep-cooling treatment chamber and the cold quantity supply equipment and used for controlling the temperature of the casting mold cooling chamber, the casting process cooling chamber and the deep-cooling treatment chamber. According to the freeze casting device and a method adopting the freeze casting device, the technological process is simple, temperature control over the casting mold cooling chamber, the casting process cooling chamber and the deep-cooling treatment chamber is conducted through the control system, and the heating rate, the cooling rate and the cryogenic temperature can be precisely controlled.

Description

technical field [0001] The invention relates to the field of metal material casting technology, in particular to a freezing casting device and method. Background technique [0002] With the continuous development of industrial technology, the traditional material casting technology is facing severe challenges. Therefore, it is imperative to upgrade the traditional casting technology. The goal of its development is to protect the environment and reduce pollution on the one hand, and on the other hand to improve the quality and reliability of castings, produce high-quality near-net-shape castings, and reduce production costs. In order to achieve the above goals, methods such as investment casting and ceramic casting have been developed to produce high-quality castings. But conventional special casting methods have many limitations. [0003] Freezing casting is a process of casting by adding an appropriate amount of water or binder to the molding sand, and then lowering the t...
