| Abstract: | Service life of the extrusion forming wheel is the key factor, which affects the cost and productivity of CONFORM. Failure of broken extrusion forming wheel and the mechanical properties of different M/B are studied. According to the different microstructures in the surface and inner segment, the heat treatment technics of extrusion forming wheel is improved. Its service life is about two and half times as long as that dealt with the original technics. |
