Abstract

The invention discloses a vacuum electron beam smelting device. The vacuum electron beam smelting device comprises a vacuum chamber and a water-cooled crucible. The water-cooled crucible comprises a crucible body and a flange plate, wherein a material pool is formed at the center of the top of the crucible body, and the flange plate is fixedly connected with the bottom of the crucible body; and a material pool peripheral side water-cooled mechanism and a material pool bottom water-cooled mechanism are further included. According to the vacuum electron beam smelting device, the water-cooled crucible, a heat source and a vacuum container are combined together, the process technology is used for vacuum metal smelting and purifying, and the safety and the reliability are improved. Especially for an installation type mechanism, a water inlet and a water outlet are formed in the outer side of the vacuum chamber, the vacuum chamber has no welding joint and machining face internally, water can flow out of the vacuum chamber even water leakage occurs, and the safety performance is guaranteed.

Description

technical field [0001] The invention relates to a vacuum electron beam melting device. Background technique [0002] Vacuum metal smelting and purification technology. In the evaporation system, a water-cooled welded copper crucible is used as the carrier of the evaporation heat source. Copper has very good thermal conductivity. Under water-cooling conditions, it can well reduce its own temperature and ensure performance. The existing cooling water channel generally adopts the water channel structure of bottom-in and top-out. [0003] Moreover, the existing vacuum electron beam melting devices directly place the water-cooled crucible in the vacuum chamber as a carrier, which leads to complicated pipeline connections in the vacuum chamber and potential safety hazards. Contents of the invention [0004] The object of the present invention is to provide a vacuum electron beam melting device aiming at the technical defects existing in the prior art. [0005] The technical sc...
