Spheroidal Graphite Cast Iron Rolls
(Nodular Iron Rolls)
These static cast Rolls are structurally characterized by nodular graphite. High Tensile strength and deep hardness penetration are few properties that nodular graphite gives these Metal Rolls. Because of excellent mechanical & material properties these Metal Rolls are capable of withstanding heavy loads and hence these Rolls are used in various Mills that produce different products. These Rolls are structurally made up of cementite and nodular graphite. Sufficient water cooling is a necessity for satisfactory performance.
Depending upon the required mechanical properties i.e. wear resistance, Roll hardness, strength, of Rolls, wide range of Rolls:
1. Pearlitic and 2.Bainitic Accicular can be made by alloying with nickel, molybdenum and chromium for added strength and deep hardness penetration.
