specific Embodiment approach 1

[0007] Specific implementation manner one: such as Figure 1 ~ Figure 3 As shown, the short cold crucible for continuous melting and directional solidification of slabs in this embodiment is composed of a water inlet pipe 4, a water outlet pipe 5, several thin water pipes 6, a copper crucible body 1, an induction coil 13, and a water inlet pipe 4 passing through Several thin water pipes 6 communicate with the copper crucible main body 1, and the water outlet pipe 5 communicates with the copper crucible main body 1 through several thin water pipes 6. The induction coil 13 is sleeved on the upper half 2 of the copper crucible main body 1; The horizontal cross-section of the copper crucible body 1 is a flat annular cavity. The copper crucible body 1 is composed of an upper body 2 and a lower body 3. The upper body 2 and the lower body 3 are integrated. The half body 2 is divided into eight petal-shaped cylinders 7 in horizontal cross-section, and eight petal-shaped cylinders 7 in ...

specific Embodiment approach 2

[0009] Embodiment 2: The insulating and sealing material layer 12 described in this embodiment is composed of natural mica flakes and epoxy resin. Choosing such a material has the best sealing and insulating effect. The other composition and connection relationship are the same as in the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation manner three: such as Figure 1 ~ Figure 3 As shown, the thin water pipe 6 described in this embodiment is welded to the water inlet pipe 4, the thin water pipe 6 and the water outlet pipe 5, and the thin water pipe 6 and the lower half 3 of the copper crucible body 1 are welded. With welding, it can withstand at least 10 atmospheric pressures. The other composition and connection relationship are the same as in the first embodiment.

[0011] Specific implementation manner 4: such as figure 1 with image 3 As shown, the length×width×height=L×W×H of the copper crucible body 1 according to this embodiment, wherein the length L is 70-80 mm, the width W is 40-50 mm, and the height H is 50-60 mm. The other composition and connection relationship are the same as in the first embodiment.

[0012] Specific implementation manner five: such as figure 1 with image 3 As shown, the length×width×height=L×W×H=72×44×55 mm of the red copper crucible body 1 describe...

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 pure copper with water cooling. Because the crucible has a water-cooled structure, the temperature of the crucible is very low during use, so the crucible itself has almost no pollution to 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 slit 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 called electromagnetic cold crucible, is a cold crucible widely used at present. Electromagnetic cold crucible technology is a new technology that has emerged in recent years. It places a split water-cooled copper crucible in an alternating electromagneti...
