Abstract

Dans un procédé de coulée pour produire des pièces moulées en fonte nodulaire, des additifs contenant du magnésium sont mélangés à la fonte lamellaire liquide dans une poche (40) pour produire un lot de fonte nodulaire qui est amené au moule pour former les pièces moulées. Les additifs comprennent un additif au magnésium (55) constitué d'un alliage de ferro-silicium-magnésium introduit tout d'abord dans la poche (40) et recouvert par une couverture de protection (56) d'additif au ferro-silicium. Les additifs (55, 56) sont placés dans un compartiment pour additifs (51) formé sur un côté d'un barrage (50) dans la poche (40). La fonte lamellaire liquide est amenée à un compartiment pour fonte (52) de l'autre côté du barrage (50) déborde finalement par dessus le barrage (50) dans le compartiment pour additifs (51) pour réagir avec les additifs (55, 56). La disposition du barrage (50) et de la couverture de ferro-silicium (56) permet un mélange mieux contrôlé de la fonte lamellaire liquide et de l'additif au magnésium.In a casting process for producing cast iron nodular castings, additives containing magnesium are mixed with the liquid lamellar cast iron in a ladle (40) to produce a batch of cast iron which is fed to the mold to form the castings. The additives include a magnesium additive (55) consisting of a ferro-silicon-magnesium alloy first introduced into the pocket (40) and covered by a protective cover (56) of ferro-silicon additive. The additives (55, 56) are placed in an additive compartment (51) formed on one side of a dam (50) in the pocket (40). Liquid lamellar pig iron is brought to a pig iron compartment (52) on the other side of the dam (50) finally overflows over the dam (50) into the additive compartment (51) to react with the additives (55, 56 ). The arrangement of the dam (50) and the ferro-silicon cover (56) allows a better controlled mixing of the liquid lamellar cast iron and the magnesium additive.
