Liquid edgebead removal device

In a rolling mill system wherein a first liquid coolant diverting and removal means is located adjacent the exit end of a mill stand for inhibiting rewetting of the top and bottom surfaces of the strip by liquid coolant and for diverting liquid coolant from the top and bottom surfaces of the moving strip so as to create substantially dry strip surface conditions and a second liquid coolant diverting and removal means is located downstream from said first mentioned liquid coolant diverting and removal means and adjacent to each of the side marginal edges of the strip for removing residual coolant from the said side marginal edges of the strip said second liquid coolant diverting and removal means comprising:

• A. a pair of combined edge contacting roller and vacuum creating units with each unit being located adjacent a separate side marginal edge of the strip and with each roller in a unit having a rigid imperforate strip contacting surface;
• B. means including window means in a unit for adjustably mounting said roller and vacuum creating units on opposite sides and adjacent each side marginal edge of the strip in opposed relationship to each other and with the roller axis of a unit being arranged normal to the top bottom surfaces of the strip;
• and
• C. means for forcing the rigid imperforate surface of the roller in each unit into a light yet substantially constant contact with a given side marginal edge of the moving strip whereby the vacuum producing elements of a unit can act in conjunction with the roller of such unit to continuously remove residual liquid coolant from a side marginal edge of the strip and present substantially coolant free strip to further strip processing equipment.

A method for removing residual liquid coolant from the side marginal edges of a moving flat rolled strip of metal as it moves from the discharge end of a rolling mill stand and subsequent to the exposure of the top and bottom surfaces of the moving strip to a dry blow-off gaseous medium and the diversion of liquid coolant therefrom comprising the steps of:

• A. simultaneously and continuously contacting each of the two side marginal edges of the strip with a separate roller to effect full free rotation of each roller;
• B. allowing each of the said rollers during the rotation thereof to separately divert externally of the roller selected portions of liquid coolant away from the respective side marginal edge of the strip with which a particular roller is associated;
• and
• C. while allowing the diversion of selected portions of liquid coolant to take place by the action of the said rollers also creating negative pressure and a separate vacuum outside of and immediately adjacent but downstream from each roller and adjacent the top and bottom surfaces of the strip so as to both independently effect removal of liquid coolant from the strip edges and at the same time enhance the containment and subsequent capture of the liquid coolant that is diverted from the side marginal edges of the strip by the rollers.
