Problems solved by technology

Due to the low strength of T2 copper, the temperature difference between the inner and outer walls of the crucible is large during smelting, which causes the crucible to deform
As the number of furnaces increases, the deformation becomes larger and larger, and the solidified shell cannot be taken out of the crucible smoothly, which eventually leads to the failure of the crucible as a whole

Abstract

The invention provides a vacuum skull furnace crystallizer and a preparation method thereof. The vacuum skull furnace crystallizer comprises a crucible body and is characterized in that a third annular slot, a fourth annular slot and a fifth annular slot are formed in the waist part of the crucible body; a third copper alloy ring, a fourth copper alloy ring and a fifth copper alloy ring are respectively arranged in the third annular slot, the fourth annular slot and the fifth annular slot and are integrated with the crucible body by the brazing method; a sixth annular slot in which a sixth copper alloy ring is arranged is formed in the bottom part of the crucible body and is integrated with the crucible body by the brazing method. The vacuum skull furnace crystallizer is difficultly deformed, long in service life, and low in cost of device repair, so that the industrial benefit is increased.

Description

technical field [0001] The invention belongs to a crucible for metal smelting, in particular to a crystallizer of a vacuum shell solidification furnace. Background technique [0002] The vacuum shell solidification furnace is used for melting and casting of high temperature active metals such as titanium, zirconium and uranium. Metal smelting is carried out in a crystallizer (crucible). During smelting, there is circulating water outside the crucible to cool the crucible. A large current passes through the crucible. The crucible is made of forged T2 copper ingot. During the smelting process, the molten metal forms a shell along the inner wall of the crucible. After the molten metal is cast, the shell needs to be taken out of the crucible. Due to the low strength of T2 copper, the temperature difference between the inner and outer walls of the crucible is large during smelting, which causes the crucible to deform. As the number of furnaces increases, the deformation becomes...
