- 16 -PROCESS FOR PRODUCING GRAIN-ORIENTED ELECTRICALSTEEL SHEET HAVING BOTH IMPROVED MAGNETICPROPERTIES AND PROPERTIES OF GLASS FILMABSTRACT OF THE DISCLOSUREThe present invention provides an annealing sepa-rator comprising from 0.05 to 2.0 parts by weightof antimony sulfate based on 100 parts by weight ofmagnesium oxide, and at least one chloride selectedfrom the group consisting of Sb, Sr, Ti, and Zr chloridesin a chlorine amount of from 5 to 20% by weight basedon 100% of the chloride and antimony sulfate, and oc-casionally comprises Ti oxide in an amount of from 0.5to 10 parts.The annealing separator is applied on the decarburi-zation annealed strip, and improves both the magneticproperties and properties of glass film, in the produc-tion of a grain-oriented electrical steel sheet.
