Specific embodiment
Referring to Fig. 1, the utility model discloses a kind of aluminium silicon carbide material stand-by equipment, including graphite crucible, stone
Black pipe 2, aluminium ingot 3, prefabricated-member mould 5, graphite bolster plate 7, seaming chuck 1 and push-down head 8, graphite-pipe 2 are arranged in graphite crucible, stone
Graphite exocoel 4 is set between black pipe 2 and graphite crucible, and aluminium ingot 3 and prefabricated-member mould 5 are arranged in graphite-pipe 2, prefabricated-member mould
SiC prefabricated component 6 is provided in 5, the top of prefabricated-member mould 5 is arranged in aluminium ingot 3, and prefabricated-member mould 5 is arranged in graphite bolster plate 7
The top of lower section, aluminium ingot 3 is contacted with seaming chuck 1, and push-down head 8 is located at the lower section of graphite bolster plate 7.
