Abstract
Procedure for manufacturing composite metal parts, particularly rolling mill cylinders comprising an outer shell and an inner core of a different nature or composition, according to which it is first poured into a mold that has the shape of the part to be manufactured A first molten metal is allowed to cool until a solidified outer shell of the desired thickness is obtained, the remaining liquid part of the first metal is evacuated and it is simultaneously replaced by a second metal of a different nature and/or composition than the first metal. In order to form the core of the piece, this second metal is poured through the upper part of the mold, characterized in that a mold is used that comprises in its lower part an evacuation hole provided with an adjustable sealing device and is cast through the top of the mold the second metal at a temperature higher than the temperature of the first metal that evades At such a rate that the level of liquid metal remains constant in the mold, the evacuation port is then closed when practically all of the excess first liquid metal has been evacuated from the mold through this port.
