Abstract

A short cooling crucible used for billet continuous melting and directional solidification relates to a cooling crucible. The invention solves the problems of a present electromagnetic cooling crucible, including adhesion between a melt and an inner wall of the crucible, discontinuous melt melting, poor melt melting, uneven composition, low power utilization and inconvenient observation. The cross section of a red copper crucible main body (1) mentioned by the invention is a flat annular hollow cavity. The upper half body (2) is segmented into eight columns (7), of which the cross sections are petal shape. Vertical deep holes are arranged on the bottom face of the lower half body (3), corresponding to the position of the columns (7) with petal-shaped cross sections. Clearances (8) are arranged between every two adjacent columns (7) with petal-shaped cross sections. The clearances (8) are filed with insulating seal material layers (12). The invention makes the low cost melting and forming with high purified materials realized. Metals float in a water cooling copper crucible and are in soft contact with the inner wall of the crucible. The strong stirring of the electromagnetic powermakes the melt components even.

Description

Technical field: [0001] The invention relates to a cold crucible. Background technique: [0002] The cold crucible is a crucible made of water-cooled pure copper. Since the crucible is a water-cooled structure, the temperature of the crucible is very low during use, so the crucible itself hardly pollutes the materials in the crucible. According to the different heating methods of the crucible, it can be divided into non-slit external heating crucible and slotted induction heating crucible. The external heating cold crucible relies on the energy generated by the energy generator to melt the material, while the induction melting cold crucible relies on Electromagnetic induction heating and melting materials, also known as electromagnetic cold crucibles, are currently widely used cold crucibles. Electromagnetic cold crucible technology is a new technology emerging in recent years. It puts the split water-cooled copper crucible in the alternating electromagnetic field, uses the...
