This paper describes the basic researches for developing the multi-component white cast irons for the hot
work rolls of rolling mill roll and the abrasion wear resistant materials of pulverizing mill by taking following
approach:
1) Alloy designing
2) Solidification structure
3) Solidification sequence and phase diagram
4) Phase transformation behavior
5) Heat treatment characteristics
The field test results for wear resistance of this type of cast iron are also introduced in comparison with
conventional roll materials
