for convenience of description, the words "upper", "lower", "left" and "right" in the present utility model, if they mean only the directions of upper, lower, left and right in correspondence with the drawings themselves, are not limiting in structure, but merely serve to facilitate description of the present utility model and simplify description, rather than to indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Term interpretation section: the terms "mounted," "connected," "secured," and the like in the present utility model are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; the terms are used herein as specific meanings as understood by those of ordinary skill in the art, and are not limited to the following terms.

Example 1

The utility model provides a copper alloy fuse-element shifts and uses hanging package, as shown in fig. 1, includes shell 2, be provided with lug 1 on the shell, the shell is inside to be provided with inside crucible 4, and inside crucible adopts the jades crucible, and the jades material crucible can guarantee further assurance fuse-element not polluted _， The inner crucible has an interior space for holding a melt, which may be a copper alloy, and an open top.

The crucible is used for containing the melt, and the lifting lug is arranged to transfer the melt in a lifting manner, so that the problems that the melt is polluted and the temperature of the melt is reduced rapidly when the melt is transferred in a melt connecting channel in the prior art are solved,

the crucible has small volume, can finish copper alloy melt introduction in a vacuum casting chamber, and can be easily transferred to the position of casting equipment; the self weight of the hanging bag is small, the cost is low, and the copper alloy melt can be safely and stably transferred and subsequently cast.

A layer of charcoal is laid on the top of the melt, and the melt is prevented from being oxidized while the melt is insulated.
