Equipment for the semi-continuous direct chill (DC) casting of sheet ingot or slabs of different dimensions, in particular for rolling purposes, including a mould frame (2) with a pair of facing long side walls (3) and a pair of facing short end walls (4). The walls of the mould 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 means for changing the mould dimensions where at least one end wall can be displaced to enable casting of ingots with different sizes, and it further includes means for indirect and direct cooling of the metal during casting. The equipment, in addition to the means for changing the mould dimensions, includes means for flexing the long side walls (3) of the mould, thereby enabling adjustment of the flexible middle part of said long side walls (3) inwardly or outwardly to adapt to the desired sheet ingot size, the desired casting speed and/or alloy composition. |
