ABSTRACT:
A prefusing crucible in a closed prefusing tank is provided above a melting crucible in a closed vacuum container. Prefusing the charge material prevents thermal shock to the melt in the crucible from which monocrystals are drawn. A cover provided over the overflow from the prefusing crucible acts as a dust trap.
