ABSTRACT:
Rheocasting is effected by an apparatus that comprises a melt tank, a temperature-controllable stirrer that is immersed in a melt contained in the melt tank and can stir the melt, a screw conveyor apparatus that can draw off metal in a semi-solid state contained in the melt tank. Vertical melt separation grooves on the inside of the conveyor apparatus enable the semi-solid into a semi-solid having a viscosity that is not less than a prescribed viscosity value and a semi-solid having a viscosity that is less than the prescribed viscosity value.
