Shot peening: Use shot peening for surface treatment, which has strong impact and obvious cleaning effect. However, the treatment of thin plate workpieces by shot blasting can easily deform the workpiece, and the steel shot hits the surface of the workpiece (regardless of shot blasting or shot peening), causing the metal substrate to deform. Since Fe3O4 and Fe2O3 have no plasticity, they peel off after being broken, and the oil film is The base material deforms at the same time, so for workpieces with oil stains, shot blasting and shot blasting cannot completely remove the oil stains.
Features of shot peening:
1. Great flexibility in cleaning. It is easy to clean the inner and outer surfaces of complex workpieces and the inner walls of pipe fittings; and it is not restricted by the site and can be moved to the vicinity of extra large workpieces for cleaning.
2. The equipment has a simple structure, low investment in the whole machine, few wearing parts, and low maintenance costs.
3. It consumes a lot of energy and must be equipped with a high-power air compressor station.
4. The cleaned surface is prone to moisture and rust.
5. The cleaning efficiency is low, there are many operators, and the labor intensity is high.
