EXTRUSION PRESS CONTAINER AND MANTLE FOR SAME, AND METHOD

摘要

A container for use in a metal extrusion press comprises 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 comprises a plurality of temperature sensors configured to measure the thermal profile within the container. The temperature sensors comprise 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.
