Abstract：In order to improve the products pass rate of wearing ring,analytical methods with process capability index and control charts are used for analysis wearing ring.The hard alloy material ratio problem of wear ring is found by analyzing,key material ratio were divided by experimental design method,and then used a new material ratio,also implemented on a small scale,the result showed a good effect,service life and wear resistance are improved as well.Slotting process was improved because of largest quantity quality problems.After improvement,the qualified products promoted from the original 93％ to 98％.Through quality management methods,the quality of wearing rings be improved greatly,which enhance the competitiveness of the company A.
