Description

Technical Field

[0001] The present invention relates to the technical field of amorphous alloy smelting equipment, and in particular to a forming and separation process for amorphous alloy ingots. Background Art

[0002] In the existing amorphous alloy ingot mold, the mold is integrally formed, and a cavity for forming the amorphous alloy ingot is constructed inside. In the amorphous alloy ingot forming mold, the cavity is in the shape of a long straight cylinder. After the metal liquid is poured into the cavity and cooled to form an amorphous alloy ingot, the forming mold is broken to take out the amorphous alloy ingot after the amorphous alloy is cooled and formed. In the cavity, the amorphous alloy ingot will be in contact with the wall of the forming mold to a large extent, and there is a large adhesion lag between the amorphous alloy ingot and the wall of the forming mold. The existing forming mold is generally formed with magnesia sand, which is difficult to take out and it is difficult to avoid bringing out mineral impurities such as magnesia sand during the removal process, or it is necessary to break part of the mold structure to take out the amorphous alloy ingot. Under the above conditions, the cavity of some molds will adopt a design scheme of being thick at the top and narrow at the bottom, but the difference between the upper and lower diameters is too small, which will still make demolding difficult, especially under the condition that the formed amorphous alloy ingot is thinner, the demolding between the amorphous alloy ingot and the forming mold is more difficult.

[0003] In addition, in existing applications, the removal process after the ingot production is completed in the forming mold requires the forming mold to be broken, which is generally not suitable for small applications (such as: the production of a small amount of amorphous alloy ingots).
