Abstract

The invention discloses an induction melting cold crucible. The induction melting cold crucible comprises a cooling water tube-in-tube(1), a base(5), a water inlet pipeline(2), a water outlet pipeline (3) and an induction coil(4), wherein the lower part of the cooling water tube-in-tube(1) is arranged on the base(5); the water inlet pipeline (2) and the water outlet pipeline (3) are arranged on the upper part of the cooling water tube-in-tube(1) respectively; and the induction coil(4) is wound around the outer part of the cooling water tube-in-tube(1). The induction melting cold crucible formed by the combination of the design idea of discrete components and the base positioning has the advantages of simple processing of parts, low production cost, further low smelting cost of certain rare metals and alloy, and big application range.

Description

technical field [0001] The invention relates to a vacuum melting equipment. More specifically, it refers to an induction melting cold crucible suitable for electron beam or ion beam for vacuum melting. Background technique [0002] Cold crucible is a kind of smelting equipment widely used for smelting active metals, refractory metals, refractory alloys or special materials. [0003] Application No. 200710072714.3 discloses a square cold crucible for continuous melting and directional crystallization. The cooling water circulation system in the square cold crucible is designed on the crucible body. [0004] Application No. 200510010297.0 discloses a rectangular cold crucible system suitable for continuous melting and directional solidification. [0005] The cold crucible in the above-mentioned publications is only suitable for smelting materials under laboratory conditions, and the melted material has the same shape as that in the cold crucible furnace.
