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
The invention belongs to a kind of Metal Melting crucible, specifically a kind of vacuum cooling-shell furnace crystallizer.
Background technology
Vacuum cooling-shell furnace is used for melting and the casting of the high temperature active metals such as titanium, zirconium, uranium.Metal Melting is carried out in crystallizer (crucible), during melting, has circulating water outside crucible, and crucible has big current to pass through, and crucible is forged by T2 copper ingot and is processed into.In fusion process, motlten metal forms scull along crucible internal walls, and after molten metal casting, scull need take out from crucible.Because T2 copper intensity is low, during melting, the crucible inside and outside wall temperature difference is large, makes crucible produce distortion.Along with heat increases, be out of shape increasing, scull cannot take out smoothly from crucible, finally causes crucible global failure.
Summary of the invention
Object of the present invention, is to provide a kind of vacuum cooling-shell furnace crystallizer, and this vacuum cooling-shell furnace crystallizer is not yielding, long service life.
Another object of the present invention, is to provide a kind of preparation method of vacuum skull crystallizer.
The technical scheme adopted is:
A kind of vacuum cooling-shell furnace crystallizer, comprises crucible body, it is characterized in that:
The yielding waist of crucible body and bottom are at least compounded with a copper alloy ring.
Described copper alloy ring is aluminium bronze ring, silicon bronze ring or Cr-Zr-Cu ring.
A preparation method for vacuum skull crystallizer, is characterized in that comprising following processing step:
1, copper alloy ring is prepared by the specification of designing requirement and size for subsequent use;
2, process ring-shaped groove respectively at the waist of crucible body and bottom, the specification of ring-shaped groove is consistent with copper alloy ring with size;
3, copper alloy ring step 1 prepared is placed in the ring-shaped groove crucible body waist and bottom offered respectively, with method for welding by copper alloy ring and crucible bluk recombination structure in aggregates.
Advantage of the present invention:
1, the bulk strength of crucible improves, and is out of shape little, and scull is convenient to be taken out, and improves efficiency;
2, long service life, proves through service test, and crucible life brings up to 800 heats from 200 heats;
3, reduce maintenance of equipment investment, improve industrial benefit;
4, the call requirement that national energy-saving reduces discharging is met.
