Steel Plate Coating Cleaning Line Features
1. Steel descaled by this system can lengthen die life, improve burning, welding and machining operations, and provide the proper surface finish for the application of modern coatings.
2. It is mainly formed by pre-heating part, descaling part, spraying paint part and drying part.
3. The descaling part formed by the cantilever centrifugal type impeller heads, the full shutter type sand separator.
4. The pills cleaning adopted high strength nylon rolls and high pressure blower second level cleaning device.
5. The pre-heating and drying part adopted various heating modes, such as electricity, fuel gas, fuel oil and so on.
6. The spraying paint part adopted the high pressure airless spraying.
7. The full line is centralized controlled by Industrial Personal Computer (IPC).
8. As the shape of steel plate is almost regular before processed, it is helpful for mechanical rust removal and automation of spraying paint, improving the efficiency of dust removing, reducing the intensity of labor and
environment pollution.
9. Mainly used in the field of shipbuilding, locomotive, antiseptic project and bridge construction industries.
