Abstract

Procedure for manufacturing grain-oriented silicon iron sheet, comprising the steps of casting a ferrous charge in a furnace, bleeding the melt into a spoon with a minimum volume of slag, adding practically the amount of silicon necessary for the final grade Desired, within the range of 2.5% to 4.0%, to degas under vacuum with agitation to remove dissolved gases and to remove impurities by agglomeration and flotation, to mold continuously while protecting the metal against oxidation, and reduce the casting to final thicknesses by rolling and annealing, characterized in that the cooling of the sheepskin formed in the continuous molding stage is carried out at the minimum speed necessary to provide sufficient surface resistance to support the molten interior of the sheeting without uncontrollable distortion.
