Comparative Study on Vibratory Stress Relief (VSR) and Thermal Stress Relief (TSR) of Cylinder Wallboard

Abstract:

Dimensional stability of carding machine has a greater impact on the performance of the Cylinder wallboard. Compared with the thermal stress relief (TSR), the vibratory stress relief (VSR) is a new technology which may eliminate the residual stress in metal components with high efficiency, energy saving, environmental protection and low cost. We have 8 pieces of cylinder wallboard castings with every 4 pieces as a group. It takes 20 minutes to do VSR in one of the groups and 20 hours for TSR in another group. Three identical size accuracy indexes are measured, respectively at intervals of 1 month 2 months after aging treatment. The results show that: the dimensional stability of cylinder wallboard vibration by VSR is better than the one by TSR. Energy consumption and cost-saving is more than 90% without "three wastes" emissions.
