Centrifugal and Static Casting Spheroidal Graphite Cast Iron Roll and Ring with Rolling Mill
2 Properties
Thanks to its higher content of Ni and Mo alloys, pearlite, bainite and martensite matrix with excellent performance are produced. The roll has the higher conductivity of thermal and high tensile strength due to the graphite is in spheroidal form. A dense net primary cementite with high wear-resistance is produced through changing the heat treatment technology and the composition of the structure with bainite, martensite and acicular nodular.


Mechanical Properties Centrifugal Static
Hardness of shell HSD50-80 HSD45-70
Hardness of neck HSD35-48 HSD35-55
Tensile Strength of core ≥450Mpa ≥300Mpa
