Реферат: Process for mfg. two-part castings comprises using a mould with a central shell and upper and lower foundry earth parts and casting a first metal into the mould until it reaches a level slightly higher than the shell to form the central part or table of the roll. After solidification of a predetermined bottom poured layer of the first metal in contact with the shell, the central mass of molten metal is evacuated through the bottom of the mould and is replaced by a second molten metal cast into the mould through the same bottom pouring channel.
