Method for reducing the coefficient of friction of the surface of metal strips and provided with a coating device for application of a metal coating on a steel strip.

摘要

Method for reducing the coefficient of friction of the surface of metal strips having a coating, particularly of steel strip (S) tinned or chromed, which are moved through a coating installation at a speed (v), characterized in that after the coating process an aqueous solution of a surfactant on the metal strip coated and moved with the speed (v), wherein the compound of water and a surfactant aqueous solution is sprayed, and leaving, after squeezed the surfactant solution and drying, a film of surfactant with a coating of 0.1 to 10 mg / m 2 on the surface of the coated metal strip.
