| Abstract: | The plasma arc surface quenching are used to harden screw surface for settling the wearing problem of the feed screw extruding machine during the feed production process. The results indicate that surface hardness is increased . plasma arc surface quenching can improve the surface hardness of the screw pole 2 3times, and the depth of harden layer is about 0.2 -0.45 millimeter. Metallurgical structure of harden layer is also analyzed and discussed. |
