The invention relates to the foundry field, and in particular to a foundry process comprising the preheating of a mold () up to a first temperature, the casting of a metal in the liquid state, at a second temperature above the first temperature, in the mold kept in a main furnace () at the first temperature since the preheating, the difference between the first temperature and second temperature being no more than 80&#xb0; C., the cooling and solidification of the metal in the mold () kept in the main furnace () at a pressure of less than 0.1 Pa at least since the casting, the removal of the mold () from the main furnace (), and the demolding of the solidified metal.

Foundry process with hot mold casting

A directional solidification cooling furnace for metal casting part comprises: a cylindrical internal enclosure having a vertical central axis and a mold support arranged in the internal enclosure; the internal enclosure comprising a casting zone and a cooling zone, the casting zone and the cooling zone being superposed one on the other; the casting and cooling zones being thermally insulated from each other when the mold support is arranged in the casting zone by means of a heat shield that is stationary and by means of a second heat shield that is carried by the mold support; the casting zone including at least a first heating device, and the cooling zone including a second heating device.
