Description

Technical Field

[0001] This utility model belongs to the technical field of forging and quenching, specifically, it relates to a quenching and holding furnace for forging. Background Technology

[0002] Quenching is a heat treatment process in which steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), held at that temperature for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to carry out martensitic (or bainitic) transformation. Therefore, the furnace used in the quenching process should have both heating and holding functions. After heating and holding, the workpiece is taken out and quenched. The handling process of the workpiece after heating and quenching and before quenching is relatively complicated, time-consuming, and poses certain safety hazards during hoisting.

[0003] In view of this, this utility model is proposed. Utility Model Content
