The Effects of Chromium-Free Insulating Coating on the Magnetic Properties in Grain-Oriented Electrical Steel
A kind of environment-friendly Cr-free insulating coating for grain-oriented electrical steel is exhibited in this paper.The tensile stress and the magnetic properties for both Cr-free and Cr-containing insulating coating were measured.The results showed that the more the coating on the metal, the bigger the tensile stress produced.The contribution of the Cr-free insulating coating to the reduction in P1.7/5o varies from 0.092 to 0.192 W/kg, while the reduction in P1.7/50 by the Cr-containing insulating coating is from 0.066 to 0.177 W/kg, with the weight of the coating varies from 4 to 6.5 g/m2.In comparison with the traditional Cr-containing insulating coating, the Cr-free coating produces larger tensile stresses in the metal, thus leads to better magnetic properties, especially in the magnetic losses.
