<p>This invention provides a film treating agent for an electrical steel sheet having excellent film characteristics such as high space factor, punchability, weldability, adhesion, etc., and having excellent lubricating property after stress relief annealing, and a production method for a non-oriented electrical steel sheet using the film treating agent. The film treating agent comprises, as principal components thereof, 100 parts by weight, calculated in terms of the solid, of at least one member selected from the group consisting of aluminum phosphate, calcium phosphate and zinc phosphate as an inorganic material, and 1 to 300 parts by weight of a coarse grain emulsion resin having a grain size of 0.3 to 3.0 mu m as an organic material.</p> |
