摘要

Perfections introduced in the object of the main patent num: 234.502 by: "process for facilitating the molding and casting in ingots of molten metals" characterized by simple or duplex exothermic agent plates having their lateral edges cylindrical surface or it coincides with increasing radius from the upper part to the lower part, which coupled together form the inner surface of the riser preventing the corrugated joint formed by each two consecutive plates the passage of molten steel, whose plates are supported by a layer of sand section appropriate, retained by metal band, finishing the construction of the sprue an exothermic agent flange in the shape of quarter rod with the flat side adapted to the interior of the ingot mold which engages the sprue preventing said flange accidental leakage of the molten steel, both for the best settlement obtained and for the cooling effect that originates on the metal solidify it (Machine-translation by Google Translate, not legally binding)
