Abstract (en)
[origin: WO8203875A1] In this immersion and vaporization fondery chamber, there is provided in the lower third portion on the side of the handling container as well as in the two upper thirds of the inner wall, an opening. The number, the size and the cross section of the openings are selected so that the total cross section Qu of the opening or openings of the lower third is equal or smaller than the total cross section area Qo of the opening or openings of the two upper thirds. According to a form of execution, the ratio Qo/Qu is at least equal to 2. The application of this chamber is characterized by the incorporation of vaporisable additives in the cast-iron, particularly pure magnesium in a handling container containing puddle bar, cast-iron or steel. The process is appropriate for the disulphurization and/or the production of vermiculated or spheroidal graphite cast-iron and malleable cast-iron.
Abstract (fr)
Dans cette chambre d'immersion et de vaporisation pour fonderie en fonctionnement, on prevoit, dans le tiers inferieur du cote du recipient de manutention ainsi que dans les deux tiers superieurs de la paroi interieure, une ouverture. Le nombre, la dimension et la section des ouvertures sont choisis de maniere a ce que la section totale Qu de l'ouverture ou des ouvertures du tiers inferieur est egale ou plus petite que la section totale Qo de l'ouverture ou des ouvertures des deux tiers superieurs. Selon une forme d'execution le rapport Qo/Qu est au moins egal a 2. L'application de cette chambre se concretise en l'incorporation d'additifs vaporisables dans la fonte notamment de magnesium pur dans un recipient de manutention contenant du fer brut, de la fonte ou de l'acier. Le procede convient pour la desulfuration et/ou la fabrication de fonte a graphite spheroidal ou vermicule et la fonte malleable.
