| titleOfInvention | Method for preparing large and high-performance O-shaped sealing ring |
| abstract | The invention discloses a method for preparing a large and high-performance O-shaped sealing ring. The method comprises the following steps: step a, selecting materials for preparation; step b, preparing a mixed material; step c, static shaping; step d, high-temperature sintering; and step e, posttreatment of the sealing ring. The method for preparing the large and high-performance O-shaped sealing ring is reasonable in arrangement of working procedure, simple and convenient in preparation process, moderate in cost, long in service life, stable in performance, and particularly suitable for a hydraulic cylinder and a heavy-load high-pressure hydraulic cylinder for metallurgical equipment; and the prepared sealing ring has remarkable performance, has good high temperature resistance, wear resistance and corrosion resistance.. |
