Steel plate pretreatment line

The steel plate and section steel pretreatment line refers to the process of applying a layer of protective primer and drying the paint film after the steel is shot blasted and derusted before processing. After the plate is pretreated, it can improve the corrosion resistance and fatigue resistance of the component.

The pretreatment line is mainly composed of conveying system, preheating device, shot blasting cleaning, painting, drying system, dust removal and paint mist treatment system, electric control system, etc. According to different models, the processing width is between 1m and 5m, and the pretreatment production line has been widely used in industries such as shipbuilding, automobile, ship recycling, elevator, chemical industry, locomotive and so on.

The steel plate pretreatment production line produced by our company has the following characteristics:

The whole machine adopts PLC automatic control, with color touch screen man-machine interface, high degree of automation, simple operation and maintenance;

The whole line transportation adopts frequency conversion speed control;

Paint reciprocating mechanism adopts special reciprocating slide module, driven by imported servo motor, with high precision and low noise. Reliability is good.

The airless spray system of the American Graco company is adopted, and the spraying is uniform and reliable. Less maintenance work.

The dust is removed by the pulse-reverse filter cartridge, which is environmentally friendly and economical, and has a high dust removal efficiency.



product description

QXY series steel pretreatment lines are mainly used for surface treatment of steel plates and various types of steel (refer to preheating, rust removal, painting, drying), and can also be used for surface shot blasting cleaning and strengthening of metal components.

This series belongs to the roller table type shot blasting machine, which is mainly used for stress relief and surface derusting and cleaning of large I-shaped steel and other high-level steel structural parts in the construction and bridge industries. This series uses a motorized roller table that penetrates the cleaning room. It is a workpiece carrying device. The workpiece is blasted and cleaned by various positions of steel grit while advancing on the roller table, so as to work continuously. It is suitable for steel pretreatment and surface derusting and strengthening treatment of long steel structure.

product description

The steel pretreatment line is a device for steel shot blasting and derusting and coating with a layer of protective primer before welding. The total length of the equipment is about 70 meters and about 150 tons. The equipment is fed into the roller table and rained. Cleaning device, preheating room, shot blasting and derusting system, shot cleaning room, intermediate roller table, paint spraying room, drying room, code printing, feeding roller table, shot blasting dust removal system, paint mist treatment system and electronic control system, etc. composition. After pretreatment of steel, the corrosion resistance of mechanical products and metal components can be improved, the fatigue resistance of steel plates can be improved, and their service life can be extended. At the same time, the state of steel surface technology can be optimized, which is beneficial to CNC cutting machine blanking and precision blanking. In addition, due to the regular shape of the processed steel, which is beneficial to mechanical rust removal and automatic painting, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution. In recent years, due to the use of programmable controller control, the degree of automation of the equipment has been improved to a greater extent.
