Main equipments in process flow as follows:
Manually loading → entry saddle → coil loading trolley I# &II# → decoiler I# &II# → decoiling scraper I# &II# → 5-roller pinch straightener I# &II# → crosscut shearer I# &II# → vertical guide roller → welder → crescent shearer → pinch machine → entry looper → scale breaker → tensioner → vertical guide roller → acid pickling trough → washing trough → edge blowing device → vertical guide roller → hot air dryer → tensioner → exit looper → tensioner → crosscut shearer → exit pinch machine → recoiler (EPC) → coil unloading trolley → exit saddle → manually unloading
Process flow of continuous pickling line

This system allow manual control interface in the pickling effect unqualified when artificial intervention, and real-time data recording, the formation of large data, the future through big data analysis, according to the acid concentration and temperature, the shape parameters, automatic formation of reasonable pickling process.
1. track is shared with an enclosed single beam, with a distance of about 32 meters.
2. configuration holder 2 sets, single set of hand load 10T, running speed of 10-20m/min;
3. supporting hand is equipped with vehicle control PLC, frequency converter, wireless communication module, code reader, track locator, RFID recognition system and so on to control the original device, and the protection level of electric control box is IP65.
4. system uses the sliding contact line, the collector supply of the car power supply; all units and the main control system adopts industrial control between wireless Ethernet, implementation of vehicle PLC and ground PLC master data exchange.
