Abstract
PURPOSE:To form an MgO-SiO2 insulating film on steel plate by the procedure in which, in the manufacture of a high-magnetic flux density grain-oriented silicone steel plate containing a normal grain growth inhibitor, the steel plate is subjected to decarburization and annealing, coated with an annealing separating agent of MgO, etc., wound around a coil, and then subjected to a secondary recrystallization final annealing at a specific temperature. CONSTITUTION:A silicone steel material, containing <0.06% c, <4.0% Si, 0.005-0.20% Sb as a normal grain growth inhibitor, and 0.10% or less Se or S, is hot-rolled into a 3.0mm thick plate. Then, the steel plate is repeatedly annealed and cold-rolled into a 0.30mm thick steel plate, then defatted, and lastly to subjected to a decarbo-annealing in the atmosphere of nitrogen containing wet hydrogen, where the surface is oxidized in a proportion of 0.7-2.8g/m<2> of oxygen. Then, the surface is coated with MgO as an annealing separating agent, and then the steel plate is wound around a coil and heated at 800-920 deg.C for 10-100hr to develop secondary recrystallized grains, and further heated at 1000-1200 deg.C to form a forsterite (2, MgO-SiO2) insulating film on the surface.
