Research On Quality Control In Rolling Mill Bearing Production Process Of Wafangdian Bearing Group Co.Ltd

As an essentia and important component in mechanical equipment,bearing playsan important role in the national economy and national defense construction.Although bearing industry has obtained the rapid development in our countrynow,some upscale market and special field will still depend on import, and bearingquality also need to constantly improve. Bearing life and reliability are notcompletely satisfy the requirements of the development of host as the leader of thebearing industry,Wafangdian Bearing Group Co.Ltd although have a certainadvantage in the capacity but also need to further improve in the bearing quality,especially the complain for rolling mill bearing is rising now and Rolling mill bearingoccurrence quality problem frequently.The main failure types of four row cylindricalroller bearings, used in rolling mills, are fatigue flakings, cracks on the racewaysurfaces, and the premature damage of cages。Therefore, it is necessary for us toresearch the reason of influence the quality for further In order to improve the servicelife of the bearings. won the recognition of users.This article through to research on quality control in rolling mill bearingproduction process of Wafangdian bearing group Co.Ltd,in order to improve thequality of rolling mill bearing and Solve the mill bearing life and low reliabilityproblems to adapt to the needs of the market. It will enhance the enterprise thecompetitive ability and strive for the early realization of a domestic bearing replaceimported.First,It has a simple analysis to rolling mill bearing product development trendin Wafangdian Bearing Group Co.Ltd, and through the contrast with foreign millbearing, clearing the existing gap. It also analyzes quality management status ofWafangdian Bearing Group Co.Ltd.Then,it statistics the frequent quality problems of rolling mill bearing appearing in the user.It also reach a decision that theprocessing capacity of equipment bearing design method is affect the bearing of themain causes of quality problems. And to reform the equipment and the optimal designof rolling mill bearing products, to improve the quality of the rolling mill bearing andimplemented the quality control of production process.Implement the productionprocess quality control. The fourth chapter through the quality control of continuousimprovement are discussed. The rolling mill bearing quality control as a long-termquality behavior to control. In order to get the stable product quality. In this paperbased on the theory of quality management. In this paper based on the theory ofquality management. Mainly through the steel mill to visit for rolling mill bearing inthe user use case. And the statistical method to analyze the influence of rolling millbearing life analysis of the causes. Use quality management knowledge to the processof production quality control. Through the study of this paper,to solve theWafangdian Bearing Group Co.Ltd mill bearing the problem of low service life, tomeet the requirements of the user.
