    摘要： The present invention provides an insulating film-forming composition in which a mixed resinous liquid obtained from a specific proportion of an aqueous emulsion of an acrylic resin and/or an acryl-styrene base resin and an aqueous dispersion of PAN free substantially from any emulsifier/dispersant is added to and mixed with an inorganic film-forming composition containing as the main component a chromate or a chromate plus a phosphate, which has conventionally been used in the prior art, in a specific proportion, and a method for forming an insulating film by coating and drying such a composition on an electromagnetic steel plate. A substantial portion of the starting materials can be commerically available products. With the composition, provided to have a longer pot life, and method of the present invention, an efficient coating can be carried out, while suppressing foaming to a consideraly low level, thereby obtaining an insulating film excelling in insulating properties and other film properties.

    摘要： A process for the partial hot dipping of a long steel strip is disclosed which comprises forming an oxidation-inhibiting film, oxygen-impermeable and thermally stable in a hot-dipping bath, which film is produced by the chemical reaction of an iron content in the steel strip with an oxidation inhibiting film-forming agent, such as an inorganic phosphoric acid compound, on a predetermined area of the steel strip surface, forming, as required, an intermediate layer comprising an inorganic binder, such as water glass, on the resulting film, forming a carbon-containing, plateing-stopping film as a top coat on the intermediate layer, and hot dipping the steel strip.

    摘要： An aluminum coated steel sheet having excellent formability and corrosion resistance comprising a steel substrate of a recrystallized structure, an Al--Si coating layer of a recrystallized structure on at least one surface of the substrate, and a discontinuous intermediate layer of Al--Fe--Si intermetallic compounds. The product may be conveniently produced by rolling an Al--Si hot dipped steel sheet and annealing the rolled sheet under suitably selected conditions.
