Die Vereinigte Leichtmetall-WerkeGmbH Bonn扩建了一台7200吨油压挤压机。图1是Hydraulik厂制造的第一台钢板——框架结构的重型卧式长行程挤压机(海面有五块轧制钢板)。由于此挤压机具有大直径的挤压筒和高比压,所以此挤压机不仅可挤压断面尺寸大的工件,而且还能生产极薄壁的管材和型材。 Die Vereinigte Leichtmetall-WerkeGmbH Bonn has expanded its 7200 tonne hydraulic extruder. Figure 1 is the first steel plate-frame heavy horizontal long-stroke extruder manufactured by Hydraulik (with five rolled steel sheets on the sea surface). Due to its large diameter extruder barrel and high specific pressure, this extruder not only extrudes workpieces with large cross-sections, but also produces very thin-walled pipes and profiles.
