Rolling wheel heating temperature of the heating temperature on the relative impact of the process and along the rolling wheel sectional temperature distribution, but also affect the size of deformation after quenching. Cooling medium medium using nitrate bath 300-320 ℃ of rolling wheels processing, isothermal 10min after Bathing air-cooled, small deformation. Rolling wheels rolling wheel is a mold at room temperature deformation of metal machining, high precision requirements. When rolling processing of metals, accept large cyclical squeeze pressure and friction in the circumferential direction, more severe operating conditions, it is damaged methods are: wear, cracking, chipping teeth. Rolling wheel information Cr12MoV perhaps mainly Cr12, there 9SiCr Dongguan rolling wheels wholesale, CrWMn, the former has a high hardenability, red hardness and high wear resistance, the latter hardenability poor, use less. In order to improve the steel arrangement, progress their patience, to further add abrasion resistance, at home and abroad have done a lot of research work, open announced a number of new steel. If China's LD, ER5 and GM steel, Japan, TCD, AUF11, DC53 steel. Rolling round production process: casting - annealing - rough - heat treatment - face grinding - molars. Selection process rolling wheel bolts are usually greater than or equal external threads 10.9 high-strength fasteners, hardness of about 35 ~ 4 0HRC. Experiments M14 × 2 and M12 × 1.75 Dongguan rolling wheel bolt suppliers, information SCM435 rolling wheel, a small amount of rolling round in 2000 the number of bolts on the lack of processing attack early failure, mostly rolling wheel bolts in 4000 to process 6000, due to fatigue failure threaded and void.
