Causes of deformation of steel grille
Libere o tempo:
Dec 25,2023
There are many reasons for the deformation of steel grates, such as the size is very large, the material is not thick enough, and the hot-dip galvanizing in the surface treatment process. In the welding process, if affected by some high-temperature heat sources, the weld zone will be rapidly heated and partially melted, resulting in the material being heated and expanded, while the relatively low temperature area around the welding zone will be bound, resulting in elastic thermal stress, resulting in thermal compression and uneven shortening deformation [.] In addition, the severe impact of external forces during loading and unloading will also cause deformation of the steel grille.

In order to avoid the deformation of the steel grid, the input heat source energy can be controlled reasonably in the manufacturing process, which is of great significance to the quality of the steel grid plate weldment. In addition, during the surface treatment process, care should be taken to avoid being carried out at high temperatures to avoid deformation. For the steel grille that has been deformed, some simple and easy to operate methods can be used to correct, but be sure to pay attention to the force cannot be too large, otherwise it will backfire. If the deformation is serious, it can only be re-produced
