Abstract
A process for producing pigs as finished products using molds equipped with at least one spout with a stairway-shaped profile having at least two steps. The molds are filled from a ladle containing molten metal via a movable runner equipped with a handling means. The steps of the spout or spouts during the filling of a mold, and the sudden movement of the runner are observed in order to direct the casting jet outside the mold, while acting on the handling means, as soon as the molten metal spreads over a specified step of the spout.
