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.
Claims13
Device for fast cooling and solidifying molten materials with a metal oxide base which exhibits two horizontally-mounted metal cylinders having parallel axes of rotation which form a plane, said metal cylinders each having outside surfaces which rotate in opposite directions said device being provided with cooling devices which are adapted to cool said metal cylinders, each outside surface constituting a rolling periphery which is a corrugated surface having consecutive recesses and elevations, one of said elevations of one of said metal cylinders engaging one of said recesses of said other metal cylinder, and said outside surfaces of said metal cylinders at said plane forming a free gap of at least 0.5 mm and at most 10 mm.
