PROCESS FOR DIRECT TREATMENT OF LINKS FOR TRACTORS OR TRACKED VEHICLES

摘要

The invention refers to a process for direct heat treatment of track links for tracked vehicles, utilizing the residual forging heat of the links themselves so as to reduce production costs.
The heat cycle as per the invention calls for careful control of forging times and temperatures, followed by an interrupted cooling sequence, without ever arriving at room temperature except when the part is completely forged and treated.
Several particular embodiments of the cycle are indicated, to achieve the final desired metallurgical structure.
