Abstract
L'invention concerne le domaine de la fonderie, et en particulier un procédé de fonderie comprenant le préchauffage d'un moule (1) dans un four (100) jusqu'à une première température, la coulée d'un métal à l'état liquide, à une deuxième température supérieure à la première température, dans le moule maintenu dans le four à la première température depuis le préchauffage, l'écart entre la première et la deuxième température n'étant pas supérieur à 80°C, les refroidissement et solidification du métal dans le moule (1), et le démoulage du métal solidifié.
