Annealing separating agent composition for grain-oriented electrical steel sheet, grain-oriented electrical steel sheet, and method for manufacturing grain oriented electrical steel sheet

Abstract:

Provided is an annealing separating agent composition for a grain-oriented electrical steel sheet, a grain-oriented electrical steel sheet and a method for manufacturing a grain-oriented electrical steel sheet. The annealing separating agent composition for a grain-oriented electrical steel sheet according to an embodiment of the present invention contains 30 to 70% by weight of a calcium compound, and the remainder of magnesium oxide or magnesium hydroxide on a solid basis.
