Abstract

1. Feeder for castings (1), in particular of cast-iron with a body (3) of an exothermic heating material comprising a cylindrical cavity (5), which material keeps the substance located in the feeder molten until the completion of the shrinkage of the casting material through the region of the casting to be fed, in which case the feeder volume corresponds to the quantity of the shrinkage volume plus the maximum safety amount of 30% of the shrinkage volume, characterised in that the cylindrical cavity (5) is open towards the outside on its upper side and that located in this cavity (5) is a float (9) adapted to its cross section and able to move with respect to the body (3) of exothermic heating material, which float likewise consists of an exothermic heating material.
