Generally speaking, the impact of shot blasting machine on steel is mainly in strength, angle, direction, time and so on. When the above factors are inappropriate, it may lead to steel surface deformation. For the problem of steel plate running round, it is caused by improper operation in most cases.
Specifically, the following factors may cause the steel plate to deviate:
1. Shot blasting strength is uneven. If the shot blasting force is not uniform, it will lead to the uneven distribution of friction on the surface of the steel plate and make the steel plate deform during operation.
2. The steel plate is not clamped. If the contact area between the steel plate and the shot blasting machine fixture is not large enough or the fastening method is incorrect, the steel plate will gradually deform during operation.
3. The shot blasting time is too long. If the shot blasting operation time is too long, it will lead to the continuous impact and wear of the steel plate surface, accelerate the fatigue and deformation of the steel plate surface, and thus form arc deformation.
Therefore, the key to avoid the problem of steel plate running round is to operate strictly according to the instructions of shot blasting machine, set reasonable shot blasting parameters and strengthen inspection during operation, and take effective measures in time to reduce the deformation of steel plate as much as possible. At the same time, when purchasing shot blasting machines, we should also choose reliable equipment, giving priority to the professionalism and after-sales service of manufacturers.
