Nodular Pearlitic Cast Iron Roll. The strength of the spheroidal graphite(SG) or nodular cast iron is a result of a change in morphoglgy of flake graphite into graphite spheroids. The lower surface area to volume of the spheroids increases its fracture toughness and hence reduces crack propagation.
Nodular Iron Special Cast Steel hese staticcast ductile rolls are structurally characterized by nodular graphite. Nodular graphite gives these rolls great tensile strength, enabling them to withstand heavy loads. Ductile rolls are structurally made up of cementite, matrix, and nodular graphite. Increasing roll hardness through the addition of ...

magnesium produces it. In the nodular graphite''s iron roll, the free carbon takes the shape of spheroids or nodules, thereby eliminating the notch effect of flake graphite and improving upon the mechanical properties of the cast iron. The nodular cast iron rolls are characterised by the nodular shaped graphite in the microstructure.

Dec 08, 2013· In the nineteenth century basically non alloy grey iron and forged steel was used for rolls. The cast iron grades varied from mild hard to clear chill, where the barrel showed a white iron layer with grey iron core and necks. These rolls were used for flat rolling without any roll cooling in the sheet mills. Later cast steel rolls were developed.

Unlike cast iron rolls, these rolls have heat treatment application during its production. Due to their tough behavior, the rolls are very suitable for light section mills and medium section mills where the deep grooves are applied for roll pass design. The rolls receive a multistage, high temperature
