Problems solved by technology

When the sample is prepared by this method, one end of the sample has a high-temperature melt, and the other end has a cooled liquid alloy, and the temperature gradient is relatively large. When growing at a higher speed, the melt is easily extinguished, causing the experiment to fail, and the liquid alloy is likely to Contaminated sample

Embodiment Construction

[0041] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0042] like figure 1 As shown, an electromagnetic levitation water-cooled copper crucible includes a crucible body 1, an induction coil 2, a copper mold 3, a compression plug 4, a rubber pad 5 and an insulating tape 6, the induction coil 2 surrounds the upper part of the crucible body 1, and the copper mold 3 is set In the copper mold cavity 13 of the crucible body 1 and fixed and leak-proof by the compression plug 4 and the rubber pad 5, the upper part of the crucible split 11 on the crucible body 1 is wound with an insulating tape 6.

[0043] like figure 2 As shown, the shape of the crucible body 1 is cylindrical, and its upper part includes eight crucible segments 11 distributed in a circle. The crucible segments 11 form an upwardly open melt cavity 12; there are gaps between the crucible segments 11. The valve gap is filled with high tempe...

Abstract

The invention discloses an electromagnetic suspension water-cooling copper crucible, and relates to the field of metal or alloy smelting equipment. The electromagnetic suspension water-cooling coppercrucible comprises a crucible body, an induction coil, a copper mold, a pressing plug and a rubber gasket, wherein the upper portion of the crucible body is surrounded by the induction coil, and the copper mold is arranged in a copper mold cavity and fixed with the pressing plug and the rubber gasket for preventing air leakage. According to the electromagnetic suspension water-cooling copper crucible, when metal or alloy is smelted, melt contamination can be avoided, so that high cleanliness of a melt is achieved; when the electromagnetic suspension water-cooling copper crucible is used for preparing specimens or bar materials, singleness of the cross sections of the specimens or bar materials can be avoided, the specimens or bar materials prepared through the electromagnetic suspension water-cooling copper crucible are small in crystal grain, and the mechanical property of the materials is improved.

Description

technical field [0001] The invention relates to metal or alloy smelting equipment, in particular to an electromagnetic levitation water-cooled copper crucible. Background technique [0002] The smelting of metals or alloys is usually smelted in a ceramic crucible in an atmospheric environment. In such a smelting method, the ceramic crucible is likely to pollute the melt, which brings certain difficulties to the purification of the later melt; the melt is in the atmospheric environment. It may also cause oxidation and burning loss of melt components, which brings certain difficulties to accurate component control. In view of this, in order to reduce or avoid melt contamination, the following technologies have been developed. [0003] Optical levitation technology can also avoid melt contamination. Optical levitation technology uses a halogen lamp as a heat source, uses a concave mirror near the filament to focus the light emitted by the filament on a point, and the rod melts ...
