DISPOSITIVO DI RAFFREDDAMENTO E PROCEDIMENTO PER RAFFREDDARE OGGETTI ESTRUSI

摘要

Continuous extrusions (7) are cooled by passing them through a cooling medium in a cooling chamber at below atmospheric pressure. Means (66) are provided to remove larger amounts of heat from the surface of the parts (110-115) which carry a greater concentration of heat energy than from immediately adjacent parts (120-123).
