II. Advantages of Vibration Aging to Eliminate Residual Stresses
◆ Timely and effective results
Extensive research and practical applications have demonstrated that vibration aging provides superior时效 effects on workpieces compared to coal, heavy oil, or gas-fired heat aging furnaces, and is nearly equivalent to the effects of electric furnaces. Vibration aging not only overcomes the challenge of uneven furnace temperatures in heat aging furnaces, leading to uneven stress relief, but also avoids the impact of reduced deformation resistance due to heating. Consequently, workpieces treated with vibration aging generally exhibit over 30% higher dimensional stability compared to those treated with conventional heat aging.
Low investment, cost-effective
The price of vibration aging equipment typically ranges from 20,000 to 80,000 yuan, which is sufficient for the aging treatment of workpieces under several hundred tons. However, constructing a thermal aging furnace for large workpieces requires an investment of several hundred thousand yuan and occupies a significant amount of space, making its application inflexible. Moreover, it may not be cost-effective to start a furnace with few workpieces or when workpieces are too large to fit inside the furnace.
Adaptive and versatile
The use of vibration aging technology is unrestricted by site, workpiece size, shape, weight, etc. Since the vibration aging equipment weighs only a few dozen kilograms, on-site aging treatment can be performed for large workpieces. Additionally, aging treatment can be scheduled between different processing steps of the workpiece according to process requirements.
◆ No environmental pollution issues.
As environmental demands rise, the issues of flue gas, dust, and slag from heat aging kilns have been restricted, while vibration aging can completely avoid them. This is why vibration aging technology has been actively applied.
Significant Energy Savings
Vibration aging treatment consumes only a few degrees of electricity per cycle, which is 95% more energy-efficient compared to heat aging.
◆ Efficiency-boosting
Natural aging requires 6 months to a year, thermal aging needs several to dozens of hours per cycle, while vibration aging can be completed in just ten to fifteen minutes to an hour.
◆ Stress-relief treatment for workpieces unsuitable for high-temperature aging
Stainless steel components, non-ferrous metal parts, and mechanical parts post-weld repair, etc.
