Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology, specifically to a uniform tempering device for heat treatment of fully threaded studs. Background Technology

[0002] Tempering is a metal heat treatment process that involves reheating a quenched metal workpiece to a certain temperature, holding it at that temperature for a period of time, and then cooling it. The purpose of tempering is to reduce or eliminate internal stress in the quenched workpiece, lower its hardness and strength, and improve its ductility or toughness. Through tempering, the performance of metal workpieces can be optimized to meet different application requirements.

[0003] Fully threaded studs require tempering during heat treatment. This involves reheating the quenched workpiece to a specific temperature and holding it there to maintain its high hardness and wear resistance, while reducing residual stress and brittleness. Currently, a mesh belt tempering furnace is commonly used for tempering fully threaded studs. Stacking the studs on a conveyor belt can easily lead to uneven heating, affecting the tempering effect.
