Abstract

A method for producing a strip using a rapid solidification technology is provided. A melt is poured onto a moving outer surface of a rotating casting wheel, the melt is solidified on the outer surface and a strip is formed. A gaseous jet is directed at the moving outer surface and the outer surface of the casting wheel is worked with the jet. The jet comprises CO2 and at least part of this CO2 strikes the moving outer surface of the casting wheel in a solid state.
