| Abstract: | The technological parameters of tube extrusion of GH1140, such as blank temperature, mould preheating temperature, choice of lubricant, ratio of extrusion, and extrusion speed, are determined by experiment in this paper. The extrusion force and influence factors are also studied. From the results of experiment, it is found that extrusion force is related to deformation temperature, mould temperature, ratio of extrusion, lubricant and deformation velocity. |
