Process Flow
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
Loading manually →Coil loading car→No.1 payoff reel → No.1 payoff

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.
