Abstract

The invention discloses a temperature-controlled cooling process and device for forge pieces, and relates to the technical field of forge piece processing. The temperature-controlled cooling process includes the steps that (1) a forge piece is taken out and placed on a mesh belt after finish forging; (2) the forge piece to be processed is subjected to primary cooling and refrigeration treatment byan air blower; (3) the forge piece processed in the step (2) is turned over, and secondary cooling and refrigeration treatment is conducted; and (4) the forge piece after temperature-controlled cooling process in the step (3) is taken out from the mesh belt, placed in air and cooled naturally to the room temperature, and the finished forge piece is obtained. According to the adopted temperature-controlled cooling process, secondary heating is not needed, and the cost is saved; the internal organization and grain of the forge piece are cooled directly under the condition of forging and crushing, grain growth caused by secondary heating is avoided, a metallographic phase and the grain size are more uniform than that of the forge piece treated by normal heating, and the mechanical property of the forge piece is higher than that of the forge piece treated by normal heating.

Description

technical field [0001] The invention relates to the technical field of processing forgings, in particular to a temperature-controlled cooling process and equipment for forgings. Background technique [0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. Forgings must be heat treated after forging. Heat treatment eliminates stress, prevents white spots on forgings, and improves the uniformity of chemical composition. Usually, heat treatment requires secondary heating, which increases resource consumption and high production costs; and secondary heating causes grain growth and reduces the mechanical properties of forgings. Contents of the invention [0003] The object of the present invention is to provide a forging temperature control cooling process and equipment in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The invention provides...
