The present invention is achieved in that
A kind of gold plate and gold ingot quick molding method, said method comprises the steps:
Gold is placed the graphite cuvette that adopts graphite to process;
Graphite cuvette is placed heater; Heater is around graphite cuvette or both sides heating; Utilize the heat transmission of graphite that the gold in the graphite cuvette is melted, the bottom of graphite cuvette is movably set with cooling device, and cooling device does not contact with graphite cuvette in heating process;
After the gold fusing, stop heating, cooling device is contacted with the bottom of graphite cuvette fast, the gold liquation in the graphite cuvette is carried out fast-refrigerating, the rapid cooling forming of gold liquation;
Gold plate behind the cooling forming or gold ingot are taken out.
Optional, the heating fusion process of said gold carries out under inert gas shielding.
Optional, the heating fusion process of said gold carries out under vacuum condition.
Optional, the heating fusion process of said gold carries out under conventional atmosphere.
Optional, said heater is an induction heating apparatus;
