Steel Plate Pretreatment Line

Steel Plate Pretreatment Line

Introduction
Steel plate pretreatment lines are used to derust steel castings and apply protective primers onto the surface before these steel castings accept welding treatment. Pre-treated by steel plate sandblasting devices, steel surface is evenly roughened with dense pits which make steels easy to paint. In this way, steel castings are corrosion resistant and durable. Because of high surface cleanness, processed steels are suitable for precise CNC cutting process. Besides, shot blasting and painting procedure can increase steel processing efficiency, decrease labor intensity and make steel processing environment-friendly.

Constitutions
Steel plate pretreatment lines are composed of crosswise steel loading units, roller conveyors, steel cleaning devices, pre-heating rooms, shot blasting derusting systems, after-shotblasting cleaning rooms, intermediate inspection roller ways, painting rooms, drying rooms, runout tables, crosswise steel unloading units, dedusting systems, paint spraying systems, electrical control systems, etc. In steel plate sandblasting devices, programmable controllers are applied to make operation easy and highly automated.
