Apparatus and method for producing a strip using a rapid solidification technology, and a metallic strip

Abstract

An apparatus for producing a strip using a rapid solidification technology is provided. The apparatus includes a rotating casting wheel with an outer surface onto which a melt is cast. The melt solidifies on the outer surface to form the metal strip. The apparatus also includes a nozzle or other means for directing a jet comprising CO2 onto the outer surface of the casting wheel. The jet comprises CO2, and at least part of the CO2 strikes the moving outer surface of the casting wheel in a solid state to work and/or clean the outer surface of the casting wheel with the jet. The apparatus further includes a nozzle system for forming the jet.
