Summary: | The apparatus for extruding a material includes a block 3 with two or more extrusion containers composed of heat resisting material. The containers are arranged to receive billets 2 of the extruding material. A die set 4 is arranged downstream of the block including the two or more extrusion containers. One or more rams 1 are aligned with the axes of the extrusion containers and are arranged to push the billets of material through the extrusion containers into the die set. The die set includes an upper die with two or more extrusion channels for extruding material from each of the extrusion containers, and a lower die incorporating a welding chamber. Two or more extruded billets from each of the extrusion channels are welded together and passed out through the exit of the die set. The extrusion containers may be cylindrical and parallel. There may be rolling stands 6 downstream from the die set to reduce the extruded thickness by hot rolling. Bolsters (10, Figure 3a) may be used to hold the containers in position by hydraulic pressure. The material to be extruded includes aluminium alloys, magnesium alloys, and steels. |
