Abstract
PURPOSE: The captioned release material which obtainable by compounding either one or both of Mg(OH)2 and Al compound respectively at the specified amounts to non-hydrate MgO, and which gives the electrical steel sheet of stable magnetism and is inexpensive and permits easy coating work.
CONSTITUTION: This annealing separating agent comprises compounding either or both of Mg(OH)2; 1W50wt% and Al compound; 0.05W5wt% to non-hydrate MgO having been fired at 1100°C or more. The Al compound maybe water soluble compound such as Al(NO3)3 or fine particle form aluminum silicate compound such as bentonite which is insoluble in water. The annealing release material of this composition is wet-ground under addition of water with a ball mill or the like, after which it is coated on the silicon steel plate and is then dried, thence the steel plate is subjected to finish annealing.
