Metal oxide-based, molten materials are rapidly cooled and solidified in a device containing two metal cylinders which have parallel axes, rotate in opposite directions and are cooled. The metal cylinders have a corrugated surface, a rise in the surface of one cylinder always engaging in a recess in the surface of the other cylinder, forming a gap. …<??>The melt is cast into the gap, drawn in by force and at the same time cooled under pressure. …<IMAGE>… |
