Withdrawal roll and wrapper rolls were strengthened by build-up welding against their short-life,using PYY125 tube welding wire+SSD welding flux as build-up welding materials.Practice use indicated that steel production reached 2.65×10 5t and 3 54×10 5t respectively during the life of build-up welding rolls.The lives of rolls were increased significantly.The sticking of steels was reduced.
