Description

Technical Field

[0001] The utility model relates to the technical field of magnetic induction melting of high-purity and high-temperature materials, in particular to a water-cooled copper crucible with a magnetic suspension melting effect. Background Art

[0002] Magnetic levitation melting technology, also known as cold crucible vacuum induction melting technology, emerged at the end of the last century. It uses a copper crucible instead of a ceramic crucible and uses an electromagnetic field to suspend the molten material during the melting process, thereby eliminating contamination of the molten material by the crucible. Therefore, cold crucible levitation melting is an effective method for preparing high-melting, high-purity, active or radioactive materials. Usually, a high-frequency coil is set outside the crucible to melt the high-temperature alloy material in the melting chamber. When the power to the coil is stopped, the magnetic lines disappear, the molten material solidifies, and a material ingot is formed. Such a material ingot has good performance in the production of most precision parts.

[0003] In this regard, as disclosed in the existing announcement No. CN204438766U, a directional solidification magnetic levitation induction melting water-cooled copper crucible includes a crucible body, a water jacket and a magnetic induction coil surrounding the crucible body, wherein the crucible body includes an independent side wall assembly and a bottom wall, the side wall assembly includes a plurality of slits uniformly distributed along the circumference for the penetration of external magnetic lines of force, and the bottom wall includes a plurality of slits uniformly distributed along the radial direction for the penetration of external magnetic lines of force, and the bottom wall can be slid up and down in the vertical direction inside the side wall assembly for positioning, and the magnetic induction coil includes a high-frequency wire mesh surrounding the outer periphery of the upper half of the side wall assembly and a medium-frequency coil surrounding the lower half of the side wall assembly; with this crucible structure provided, during the metal smelting process, the bottom wall of the crucible moves downward, and the molten metal in the lower part of the smelting chamber gradually solidifies under the stirring action of the medium-frequency magnetic induction coil, and the metal closer to the bottom solidifies earlier. As the bottom wall of the crucible gradually moves downward, directional solidification and continuous ingot casting are achieved.

[0004] The above technology discloses a directional solidification magnetic levitation induction melting water-cooled copper crucible, which melts the high-temperature alloy material in the melting chamber through a magnetic induction coil, gradually solidifies under the stirring action of the medium-frequency magnetic induction coil in the two sets of magnetic induction coils, and uses the side wall water jacket for water cooling assistance. However, there are still the following deficiencies during use: when in use, it is inevitable that a lot of dust and debris will adhere to the outside of the magnetic induction coil, and there is a lack of a structure for cleaning and dust removal and sealing the magnetic induction coil for dust protection after use. The cleanliness after use is not ideal, and it is easy to affect subsequent use due to the adhesion of a lot of dust, and there is a risk of contamination of the magnetic induction coil when not in use; in view of this, on the basis of this, it is improved, and the present application proposes a water-cooled copper crucible with magnetic levitation melting effect to solve the above-mentioned problems.
