Apparatus for gravity-feed casting with a large number of ingot molds of metal of metal billets of multiple diameters

A continuous casting apparatus for multiple gravity feed casting said apparatus comprising:

• at least one row of ingot molds each provided with side and upper walls and a movable bottom;
• a corresponding cooling cell disposed externally to and spaced from the side wall of each said mold each said mold resting freely on a corresponding cooling cell and bearing against the corresponding cell by way of a seal;
• a feeder head having a base provided with an outwardly directed rim resting on the upper wall of each said mold by means of a seal;
• a removable base plate disposed above said molds supporting ducts for feeding liquid material said base plate including a plurality of openings, each said opening communicating between a said duct and at least one said feeder head,
• a removable housing provided on said base plate for each of said opening, each housing including one aperture for each feeder head with which the opening corresponding to the housing communicates, each said aperture being aligned with an opening and a feeder head which is engaged into the opening, the rim of the feeder head being fixed beneath the corresponding housings, said removable housing being separable from each other;
• means fixing each said housing to said base plate;
• and
• a plurality of interconnected refractory blocks fixed with respect to each of said housings forming said ducts and having apertures therein corresponding to the apertures in the housing and the openings in the base plate.
