Abstract
The invention discloses a water cooling crucible for an electron-beam melting furnace. The water cooling crucible comprises a base; a convex ring is formed at the upper end face of the base; the lower end of an external water jacket and the lower end of a clamping sleeve are both connected with the top surface of the convex ring; the lower end of an internal water jacket is inserted into the convex ring and connected with the base; the external water jacket, the clamping sleeve and the internal water jacket are sequentially arranged from outside to inside; a gap is formed between the outer wall of the clamping sleeve and the inner wall of external water jacket, and the clamping sleeve is in interference fit with the internal water jacket; a spiral groove is formed in the outer peripheral wall of the internal water jacket; and a water inlet pipe and a water outlet pipe are arranged at the lower end of the external water jacket, the water inlet pipe penetrates the external water jacket and the clamping sleeve to be communicated with the spiral groove, and the water outlet pipe penetrates the external water jacket to be communicated with the gap. By means of a low-in low-out water path structure, the water cooling crucible is free of cooling dead area and good in cooling effect. The internal water jacket is of a spiral structure, so that the heat exchange area is enlarged. The internal water jacket, the external water jacket and the clamping sleeve are connected through static seal structures, so that the water cooling crucible is easy to manufacture.
Description
Technical field
The invention belongs to a kind of crucible, be specifically related to a kind of electron beam furnace cold-crucible.
Background technology
Electron beam furnace is the equipment carrying out electronic torch melting, is usually used in the melting of refractory metal, alloy and compound thereof.The cold-crucible that electron beam furnace is commonly used is the waterway structure of bottom in and top out, and crucible upper end has the dead volume that cooling water does not reach, and easily causes water to seethe with excitement, and is unfavorable for cooling.
Summary of the invention
The present invention proposes to overcome the shortcoming existed in prior art, its objective is and provides a kind of electron beam furnace cold-crucible.
Technical scheme of the present invention is:
A kind of electron beam furnace cold-crucible, comprise base, base upper surface forms bulge loop, outer water jacket, chuck lower end are all connected with bulge loop end face, inner water sleeve lower end is inserted in bulge loop, and is connected with base, and outer water jacket, chuck, inner water sleeve set gradually from outside to inside, gap is formed, matched in clearance between chuck and inner water sleeve between jackets outer wall and outer water jacket inwall; Flange joint is passed through in outer water jacket and inner water sleeve upper end; Inner water sleeve outer circle wall forms helicla flute; Outer water jacket lower end is provided with water inlet pipe and outlet pipe, and water inlet pipe runs through outer water jacket with chuck and is communicated with helicla flute, and outlet pipe runs through outer water jacket and is communicated with gap.
Described helicla flute rectangular in cross-section.
Described outer water jacket and inner water sleeve upper end all form flange, and are provided with No. I sealing ring between the flange of outer water jacket and the flange of inner water sleeve.
Described chuck upper end inwardly forms flange.
Described flange stretches in helicla flute, and and there is gap between helicla flute bottom land.
