| Abstract: |
| Objective To study the influencing law of descaling parameters on pickling speed. Methods The strip sample was descaled by the tension-bending leveler. The effect of descaling parameters on pickling speed was analyzed and fitted using mathematical software, to obtain the influencing model of descaling parameters on pickling speed and analyze the law. Results With the increase of insert depth of roller and tension of descaling machine, the strip elongation increased and the pickling time reduced. The pickling time changed slightly when the screw down amount exceeded 36 mm. Conclusion Tests showed that the strip elongation was mainly impacted by the screw down amount, and the pickling time decreased insignificantly when the screw down amount exceeded the saturation point. The screw down amount affected the pickling speed exponentially. |
