1. Description

Push-pull pickling line,characteristic is higher quaility,simplicity of operation,good applicability,

low consumption and fewer faults,so it is very fit for medium and small cold rolling plant.

The  Push-pull pickling line capacity we supplied is among 100000~600000 tons annually.

It can acidwashing many kinds of incoming material
