Roll Wiping System

As auxiliary equipment of rolling mill, roller wipers are arranged symmetrically in frontend and back of the mill.

Purpose: two couples of wiper rolls form a dynamic seal to wipe off rolling oil attached on strip surface under high rolling speed (max800m/min).

Purpose: two couples of wiper rolls form a dynamic seal to wipe off rolling oil attached on strip surface under high rolling speed (max800m/min).

The system is consisting of

1. 2-roll wiping

With upper/lower roll boxes and rollers made by copper alloy material; Contact

pressure between strip and wiper roll is controlled by proportional valve.

2. 4-roll wiping

Containing 4 wiper rollers open/close controlled by hydraulic cylinder. Wiper roller is supported by ball bearing connecting with pneumatic cylinder which is controlled by proportional valve. Air purging system is also adopted.

3. Oil mist lubricator

For lubrication of backup bearing for 4-roll wiper and bearings of wiper roll.

4. Electric control system  

Automatic settings and control on working status and pressure of wiper roll relying on different width, rolling speed and direction.
