Description

TECHNICAL FIELD

[0001] The utility model relates to bar processing technical field, concretely relates to a bar stress release annealing auxiliary support. BACKGROUND

[0002] In the traditional annealing process, the bar is first heated to an appropriate temperature, which is usually higher than the recrystallization temperature of the material, to eliminate work hardening effect and improve the plasticity and toughness of the material. The heating process needs to be carried out slowly to ensure that heat penetrates uniformly throughout the bar, avoiding the generation of thermal stress and thermal cracks. After heating, the bar is kept in the furnace for a certain period of time to ensure that the internal structure of the material is fully recrystallized.

[0003] Subsequently, the bar is slowly cooled in the furnace, a process known as furnace cooling. The rate of furnace cooling also needs to be controlled properly to prevent the generation of new stresses or hardness inhomogeneity within the material. In some cases, isothermal annealing may be required to obtain specific microstructure and properties, i.e. the bar is kept at a certain temperature for a period of time before cooling.

[0004] The bar is prone to internal stress when rapidly cooled at high temperatures, and this stress concentration phenomenon increases the risk of cracking or deformation during subsequent processing. In addition, this process relies on electric heating furnaces for temperature control, which not only leads to low energy efficiency but also requires high maintenance costs. Therefore, we propose a bar stress release annealing auxiliary support. SUMMARY
