| Abstract: | According to the working condition of roll, a new alloy composition was developed and melting and pouring has been modified. The new alloy and process can improve quality and surface quality of roll with higher strength in core section, less broken of roll, less porosity, shrinkage and melt in defects. The productivity has been improved significantly. |
