| PURPOSE: To obtain a title steel plate with excellent magnetic property by a method wherein, on a subscale formed on a surface of a cold rolled directional silicon steel plate after decarburization and annealing, an annealing separating agent comprising each specific amount of water containing silicate mineral fine powder, a compound of Sr or Ba, casutic (slaked) line and balance of Al 2O 3 is coated and annealed. CONSTITUTION: On a sub-scale formed on a surface of a cold rolled directional silicon steel plate decarburized and annealed with a final plate thickness, an annealing separating agent hereinafter described is coated and, subsequently, final annealing is carried out. The said annealing separating agent comprises water containing silicate mineral fine powder (e.g.: ophcalcite, talc) 5W30% a compound of Sr or Ba 0.2W20% (as Sr or Ba), CaO or Ca(OH) 2 2W30% and balance of AlO 3. By this method, an annealing separating agent is easily released after final annealing as well as undercoating is not almost formed and a directional silicon steel plate with excellent punching processability and good magnetic property is obtained.

| PURPOSE: To form the captioned film which is even and is of good adhesive properties with good reproducibility by coating the annealing separating agent composed primarily of the magnesia which is of low activity and has a narrow activity distribution on the surface of the anisotropic silicon steel plate, coiling the same in coil form and subjecting the same to high-temperature annealing. CONSTITUTION: The annealing separating agent composed primarily of the low active MgO of a narrow activity distribution whose citric acid activities are within the range encircled by A, B, C, D, E, F, G, H is coated on the surface of the anisotropic silicon steel plate. The one containing e.g., CaO<0.50%, Cl≤0.04%, SiO 2<0.15%, SO 3<0.20%, R 2O 3<0.20%, B<0.15% and of MgO content 95% or over is used. Next, the anisotropic silicon plate having been coated with said annealing separating agent is coiled to coil form, after which it is annealed at, e.g., about 1200°C in a pole type electric furnace, while H 2 gas is being supplied. As a result, the forsterite insulation film of superior stability is formed on said steel plate. COPYRIGHT: (C)1980,JPO&Japio | ||||||
