The purpose of this study is to investigate the wear resistance of raw materials transported in high-speed impact and vibration environments during the production process of converter feed chute,enhance the service life of the chute equipment,and improve the accuracy of feeding.Method:Through innovative analysis based on TRIZ theory and using the principle of turning harm into benefit,a cavity box was added at the bend of the feeding chute,changing the structure of the areas with high impact and increased friction,and changing the friction mode between raw materials such as alloys and slag materials and the chute.The chute was transformed from material grinding to material grinding.As a result,through the improvement of the structure of the feeding chute,the traditional method of thickening the chute wall thickness and changing the chute material cannot improve wear resistance,and the lifespan of the chute cannot be significantly improved,resulting in the hidden danger of frequent replacement of the chute.At the same time,the leakage of the chute can also cause production accidents and quality accidents caused by insufficient feeding.Conclusion:The long-life transformation of the slide tube has been achieved.
