Method for manufacturing a grain-oriented electrical steel sheet

摘要

By using a treatment solution containing an Al compound in the form of a solution or a colloidal solution and a stable compound at a high temperature as an annealing separator, a superior annealing separation effect can be obtained without causing any dust problem and line contamination. In addition, when the above annealing separator is used in final annealing or the like in a manufacturing process of a grain-oriented electrical steel sheet, a grain-oriented electrical steel sheet can be obtained which has no forsterite coating or which has superior forsterite coating properties.
