Abstract
A liner for an extrusion press container comprises an elongate body having a longitudinally extending passage therein through which a billet is advanced, the passage having a generally rectangular cross-sectional profile. The liner further comprises at least one first longitudinally extending heating element accommodated by the body adjacent a first side of the passage, and at least one second longitudinally extending heating element accommodated by the body adjacent a second side of the passage. The first and second heating elements are individually controllable for controlling a thermal profile within the liner.
