METHOD FOR SMOOTHING ROLLS FOR COLD ROLLING OR FINISHING COLD ROLLING OF BRIGHT METAL SHEET OR THE LIKE

摘要

A considerable reduction of the polishing of rolls of a rolling mill for cold-rolling metals is obtained by periodically passing a blue annealed steel sheet through the rolls of the rolling mill while these exert a pressure on the sheet. The blue annealed sheet so used exerts a polishing action on the rolls, avoiding need for taking the rolls out of the stands to be polished. One blue annealed sheet can be used several times for this purpose.
