When casting the liquid metal in moulds, one wants to achieve rapid cooling and avoid oxidation of the metal surface.
Cast cooling with CO2 snow
CO2 - snow
In addition to the gases required for your process, Messer offers a variety of equipment for its optimisation under the brand names Oxipyr and Oxijet.
In order to select the optimum system, experts from Messer first carry out a comprehensive process analysis. Following calculations and basic engineering, suggestions are made for optimisation and further procedures.
Immediately after casting, cryogenic CO2 snow is sprayed onto the metallic surface resulting in rapid solidification and the prevention of oxidation taking place on the metal surface.
