摘要：
The invention relates to a method for producing a grain-oriented electrical steel flat product with minimised magnetic loss values wherein the method comprises the following work steps: a) providing an electrical steel flat product, b) applying a layer of a phosphatic insulation solution for at least one surface of the electrical steel flat product and baking the applied layer. In order that the tensile stresses acting on the surface of an electrical steel flat product are increased further by means of such a method, the invention proposes that, after a first execution of work step b) this work step b) is repeated at least once, so that from the layers of phosphatic insulation solution applied and baked one after another and one on top of the other an insulation coating is obtained.
