When it rolling grooves, there will be a less hardness drop and a better wear resistance, which is advanced to improve rolling campaign and section’s surface quality.
The key technology of producing casting roll with grooves includes the design of mould’s grooves, the formula of chilling charge and the control of casting temperature.
