Use of Lubricants on a Stretch Leveller for Steel Strip

Summary:To reduce the adhesion of contaminants to the straightening rollers of a machine designed to straighten cold-rolled steel strip that has been annealed and undergone temper rolling, it has been proposed that the rollers of the stretch leveler be sprayed from above and below with a 5.0–6.0% solution of process lubricant Volgol-355. A series of measures has been implemented to optimize the conditions under which the solution is delivered and solution residues are removed from the strip's surface. This has eliminated the formation of streaks of contaminants on the surface, reduced the number of "scratches" and "dents" formed on it, improved the surface finish of the straightened rolled product, and made it possible to begin cutting the strip and shipping it to complete customers' orders. The deviation of the strip from planarity is no greater than 2 mm/lin. m.
