2.0~4.0mm*1300mm 800000t/y Push-pull Acid Pickling Production Line
Equipment and system configuration
The uncoiling section is equipped with double pay off reels to reduce the coil loading time, improve the utilization rate of the unit and increase the capacity.
The entry section is equipped with 9-roll pinch straightener, end and angle cutting shears to ensure the passing ability of strip steel.
The pay-off reel in the entry section is powered. It can automatically uncoils coil and float to ensure the neutrality of strip steel.
The tension of uncoiling section can be adjusted, and the pressure roller is equipped to ensure the smooth operation of strip steel.
The entry section is equipped with vertical guide roller to ensure the accuracy of strip steel position in 9 roll pinch straightener and entering the process section.
The process section is equipped with backwashing section to prevent the pollution of the front section equipment when the strip is pumped back.
Squeezing roll is set between each process tank to ensure that the tank liquid is distributed according to the process requirements;
Double squeezing rollers are set at the exit of pickling tank and washing tank to improve the process efficiency.
