Abstrakt: Magnetic properties of cold-rolled electrical steel have been studied as a function of fractional deformation at reversive rolling mill under conditions of existing production. The differences in the oxide film state on rolled surface processed in various passes have been detected by metallographic analysis. Elastic tensile stresses in metal created by electric electrical insulated coating have been determined by direct measurements. It has been determined that the surface of strip rolled in lower number of passes is the most favorable for coating application. The elastic tensile stresses in this case are significantly higher. During industrial experimentation, the magnetic loss of electrical steel has decreased due to optimization of reduction mode at reversive cold rolling mill. The influence of fractional deformation on the magnetic inductance of electrical steel has been detected, which should by verified in the frames of individual study. [ABSTRACT FROM AUTHOR]
