| 摘要 |
In the present invention there is described a method for producing electric sheets, in particular grain-oriented electric sheets, with an evenly well-adhering glass film and with improved magnetic properties, in which the hot rolled strip which is produced at first and is optionally annealed is cold-rolled up to an end thickness in one or several steps, thereafter an annealing separator is applied to the strip which is rolled up to the end thickness, and is dried, and thereafter the cold strip thus coated is subjected to high-temperature annealing, whereby the main component of the annealing separator being an aqueous magnesium oxide dispersion prepared from reactive magnesium oxide and the annealing separator being additionally provided with at least one additive. The characterizing feature of the invention is that a well water-soluble sodium phosphate compound is used as at least one additive. |
