[0002] The hexagonal flange bolt is one of the commonly used mechanical parts nowadays. Bolts are usually used together with nuts to fasten and connect two parts with through holes. In the process of bolt production and processing, annealing treatment of bolts is one of the essential processing procedures. Its purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and crack tendency, refine grains, adjust the structure, eliminate structure defects, etc. When annealing bolts, usually multiple bolts are put into the annealing equipment. First, the bolts are slowly heated to a certain temperature and kept for enough time, and then the bolts are cooled at an appropriate speed;
