Abstract

See full text

Equipment for the semi-continuous direct chill (DC) casting of sheet ingot or slabs of different dimensions, in particular for rolling purposes, including a mold frame (2) with a pair of facing long side walls (3) and a pair of facing short end walls (4). The walls of the mold define an upwardly open inlet for the supply of metal and a downwardly facing outlet provided with a starter block (5) on a movable support which prior to each casting closes the opening. The equipment includes a device for changing the mold dimensions where at least one end wall can be displaced to enable casting of ingots with different sizes, and it further includes a device for indirect and direct cooling of the metal during casting. The equipment also includes apparatus for flexing the long side walls (3) of the mold, thereby enabling adjustment of the flexible middle part of the long side walls (3) inwardly or outwardly to adapt to the desired sheet ingot size, the desired casting speed and/or alloy composition.
