Equipment Main Function
1.After flattening under small rate of reduction, The CR strip coil will be eliminated certain amount of stress and yield point elongation, while in stretching and punching, the strip coil “slip line” will not appear.
2.After annealing, CR coil strip go through temper which can better improve the strip flatness(coil shape) and surface roughness.
3.By adjusting reduction rate of temper which can have certain range of variation on mechanical property
of coil strip, thus made the hardness and plasticity of coil strip could apply for different functional
requirements.
