ABSTRACT:
Device to heat the leading end of aluminium ingots to be extruded when hot in extruder presses, with chambers containing the ingots arranged turret-wise with their axes parellel, the device being arranged in cooperation with the frontal end part of a chamber (12) which will cooperate with the extruder die, and in correspondence with the position for loading and readying an ingot (13), this position being located immediately upstream of the extrusion position.
Method to heat the leading end (14) of a hot aluminium ingot (13) held in a chamber (12) located in a position to load and position an ingot immediately upstream of the extrusion position in a turret-type extrusion press, the leading end (14) being extracted from the chamber (12) and caused to protrude therefrom (12) and being then heated by induction and re-inserted thereafter in the chamber (12) immediately before the chamber (12) is placed in its extrusion position and the ingot (13) is extruded.
