Steel Plate Pretreatment Shot Blasting Machine for steel plate Cleaning
Steel plate shot blasting pretreatment line workshop site
Corrosion protection of steel products
The pretreatment line combines the heating (drying), shot blasting, coating and drying of workpieces (such as steel plates, profiles, pipes or steel structures) in an automatic production line.
When there is a long manufacturing or storage time between shot blasting and final coating, the pretreatment line will be the ideal choice. To prevent recurrence of rust, a welding primer is applied to provide corrosion resistance for several weeks.
The sheet width can reach 6000mm, and the passing speed varies from 1.0 m/min to 8.0 m/min.

The workpiece moves along the entrance of the roller conveyor to the preheater. Dry and heat them before starting work in the shot blasting machine. After shot blasting, the coating is applied in the spraying chamber, and then the finished workpiece is moved to the drying chamber. The slat conveyor conveys the parts towards the exit of the roller table. They are removed there, or sent to the downstream logistics system via a cross conveyor.
Roller conveyor entrance
The first part is the entrance roller conveyor. The steel plates and profiles are delivered here and then sent to the processing process. The entrance roller conveyor can be equipped with a cross conveyor to optimize efficiency or connect it to a logistics system.
Used to remove residual moisture. It is usually located upstream of the shot blasting machine to ensure that the workpiece is dry before entering the shot blasting chamber. The product will also be heated to reach the necessary temperature to ensure that the primer dries quickly.
The preheater is located in front of the shot blasting machine, which means that it takes longer for the plate or profile to reach the entrance of the spray booth.
This balances the inevitable temperature peaks and avoids damage to the primer.
To maximize the transfer of heat to the material while consuming the least amount of gas: the long tube burner (directly through the preheater's combustion rod with hundreds of individual flames) directly impacts the workpiece, combined with the high-speed synchronous high-speed fan Hot air circulation (about 250°C)
The variable number of controllable long tube burners makes it easy to adjust the heating performance and thus avoid the preheater being too long
Shot blasting machine
Roller conveyor shot blasting machine is the key equipment in the pretreatment line. The workpiece (plate, profile or pipe) is passed through the shot blasting machine to remove rust and scale. All equipment is equipped with a high-efficiency HAOPIN shot blaster that is easy to maintain. According to specific requirements, the shot blaster and its position can be changed, and the workpiece can be completely cleaned in a safe process to ensure that the surface finish meets the internationally recognized ISO 8501-1 preparation level.
For advanced corrosion protection, shot blast cleaning is usually required to prepare Sa 2.5. In some cases, Sa 3 may be required, which requires a significant reduction in working speed (about 50%).
Round steel shots are usually used to obtain a surface roughness of about Rz40-80μm.
