ABSTRACT:
Device and process for fast cooling and solidifying of molten materials with a metal oxide base. The device comprises two metal cylinders with parallel axes, which rotate in opposite directions and are cooled. The metal cylinders exhibit a corrugated surface, and an elevation on the surface of one cylinder in each case engages in the recess of the surface of the other cylinder with formation of a gap. The melt is poured into the gap, drawn by force and simultaneously cooled under pressure.
