摘要： 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.

摘要： A container for use in a metal extrusion press includes a mantle having an elongate axial bore therein, the bore having a first transverse axis orthogonal to a second transverse axis, and a plurality of longitudinally extending heating elements accommodated by the mantle adjacent the bore. The heating elements are individually controllable for controlling a thermal profile within the container. The container also includes a plurality of temperature sensors configured to measure the thermal profile within the container. The temperature sensors include a first temperature sensor and a second temperature sensor positioned on opposite sides of the first transverse axis, and a third temperature sensor and a fourth temperature sensor positioned on opposite sides of the second transverse axis.
