The steel structure shot blasting and painting line is an automated production line used for the surface treatment and coating of steel structures. It is mainly composed of shot blasting and cleaning equipment, painting equipment, and a conveying system, etc. The following is a brief introduction to each part:

Shot Blasting and Cleaning Part: The shot blasting machine is the core equipment of this part. It accelerates and throws the shot onto the surface of the steel structure through a high-speed rotating impeller. By utilizing the impact force and frictional force of the shot, it removes impurities such as rust, mill scale, and oil stains from the surface of the steel, enabling the steel surface to achieve a certain degree of roughness and cleanliness, and providing a good foundation for the subsequent painting process. Shot blasting and cleaning can enhance the adhesion between the steel structure and the coating, improving the anti-corrosion performance and service life of the coating.

Painting Part: It includes equipment such as a painting booth, spray guns, and a paint supply system. The steel structure that has undergone shot blasting treatment enters the painting booth. Under the operation of the control system, the spray guns evenly spray the paint onto the surface of the steel structure. The painting booth usually has a good ventilation system, which can promptly discharge paint mist and volatile organic solvents, ensuring the safety and hygiene of the working environment. At the same time, it also helps with the drying and curing of the paint.

Conveying System: It is responsible for conveying the steel structure between various processes to ensure the continuity and automation of the entire production process. Common conveying methods include roller conveyor and overhead conveyor, etc., which are selected according to the shape, size of the steel structure, and the requirements of the production process. The conveying system can also be linked and controlled with equipment such as the shot blasting machine and the painting booth to achieve the automated operation of the production process.

The steel structure shot blasting and painting line is widely applied in fields such as machinery manufacturing, automotive industry, bridge construction, and shipbuilding. It can improve the surface quality and anti-corrosion performance of steel structures, extend the service life of steel structures, and also increase production efficiency while reducing labor costs.
