Novel automatic charging device and method for powdered material under high-temperature vacuum environment

Abstract

The invention discloses a novel automatic charging device and method for a powdered material under a high-temperature vacuum environment, and solves the problem that each component of a novel alloy material as well as metal or nonmetal parts in a vacuum oven are easily oxidized at a high temperature in a conveying process of the powdered material. The novel automatic charging device comprises a vacuum stock bin arranged outside the vacuum oven, a feeding assembly connected with a discharge hole of the vacuum stock bin and used for feeding the powdered material into a crucible; and a gas exhaust valve used for vacuum-pumping is arranged between the vacuum stock bin and the vacuum system. With the adoption of the structure, the feeding device and the vacuum oven realize automatic conveying of the powdered material subjected to vacuum casting through a novel alloy powder liquid process under the vacuum environment, so that each component of the novel alloy material as well as the metal or nonmetal parts in the vacuum oven are not oxidized at the high temperature, a vacuum casting process of the novel alloy material is guaranteed; and meanwhile, the service life of a vacuum casting oven is prolonged, and efficiency utilization maximization is realized.

Description

technical field [0001] The invention belongs to the technical field of vacuum casting of new alloys, and in particular relates to a novel automatic feeding device and method for powder materials in a high-temperature vacuum environment. Background technique [0002] The new alloy powder-liquid method vacuum casting is an important metallurgical method, which is to add powder materials into the molten metal solution according to a certain proportion, stir and mix them, and then cast them into shapes. The crystallization of the metal is strengthened by the added material, and its physical and chemical properties are improved and strengthened, so as to achieve the purpose of forming a new alloy material. [0003] During the vacuum casting process, the charge is melted from solid to liquid in the crucible, and then the powder material is transported to the crucible by the feeding device for stirring and mixing. Obviously, in order to ensure that each component of the new alloy ...
