1. Description:
MA AGC Four-High Three-Stand Tandem Cold Rolling Mill
2. Main function:
It consists of the screwdown device, mill housing, roller system,
balancing device, main transmission, roller-changing device. Its
main function is to roll the strips to satisfy the required
thickness.
3. Process flow: (for reference):
Loading coil car→hydraulic expansion decoiler→pinch
leveler→hydraulic shearing, welding platform→feeding floor-type
storage looper→feeding process platform (with tension roller
device)→1# stand→2# stand→3# stand→unloading process platform
(hydraulic shear)→recoiler→unloading device
