Abstract (en)

[origin: FR2844809A1] Rapid cooling of metal components is carried with a cooling gas under pressure. The cooling gas includes one or more gases that absorb infrared radiation, to improve the heat transfer of the component in conjunction with the phenomena of radiation and convection transfer, and to improve the coefficient of convection transfer. A Independent claim is given for utilization of the method in an installation for the rapid cooling of metal components with the aid of a gas under pressure, optimized to operate with nitrogen, using a cooling gas including 20-80% of a gas absorbing infrared radiation and 80-20% of hydrogen and/or helium. The composition of the gas is adjusted so that it is not necessary to provide any significant modifications to the installation.
