ABSTRACT:
A tundish for use in casting a ribbon of crystalline or coarse grain polycrystalline material, having a support for a hopper containing molten material, the hopper having a bottom plate and three side wall plates and a top plate, each made of a material which will not interact with the molten material contained within the space defined by the bottom plate, side wall plates and top plate, to impart any significant impurity into the molten material, and wherein the top plate slants downwardly towards the bottom plate to form an elongated orifice through which molten material is extruded onto a cool surface where crystallization of a ribbon of material occurs. As disclosed, the top plate is movable with respect to the bottom plate to change the thickness of the orifice. Also as disclosed, the top plate slides in a slot in each of two opposed side walls and is of a length such that it forms with the third side wall an opening into which molten material is added to the tundish.
