ABSTRACT:
A steel extrusion apparatus is shown having an improved die stack with a direct cone geometry. The die stack includes a die holder with removable and replaceable die inserts. The die inserts are made from a high strength material while the die holder is made of a less expensive, traditional material. A hot metal billet is extruded through an orifice provided in the die insert of the die holder. The die stack assembly is retained as an assembled unit as the extrusion container is moved out of contact with the assembly and the butt end of the metal billet is discarded. The die stack assembly is then again located on the extrusion container as a unit to begin another extrusion cycle.
