Ball blank forming → ring belt removal → rough grinding → soft grinding → heat treatment → ball blank forming → light ball (or filing → soft grinding) → hard grinding → fine grinding → fine grinding (or polishing) → super fine grinding. Second, the detailed production process of steel balls 1. Wire ... read more
1) The structure of the valve ball varies depending on the method of supporting the ball The support method is divided into floating type and fixed type a: The floating ball valve is supported by the valve seat. The sealing structure is that the valve ball sticks to the valve seat on the secondary ... read more
