Rolls

Horizontal Centrifugal Cast
(HiCr, ICDP & HSS grades - Barrel dia. 600mm to 840mm)

These rolls are bimetallic and consist of a wear resistant working layer (shell material) and a ductile iron (SG) core. Working layer (shell material) hardness ranges from 65ShC to 85ShC.

Applications of these rolls include:

  • Hot Strip Mill Finishing Stands
  • Steckel Mills
  • Plate Mills

Static Cast/ Monobloc Rolls

Alloy Cast Steel (ACS), Graphitic steel and Nodular Iron (Pearlitic and Acicular) grades are monobloc and static cast. Customer hardness and microstructure
requirements are achieved through careful selection of material specification and heat treatment cycles. They vary in size (weight) from a few hundred kgs to
approximately 50 tons and are classified as large, medium or small.

Large / Heavy Rolls
(<10 ton final mass) (monobloc static cast)

  • Beams – H Sections, Rail sections, etc
  • Roughers and Breakdown rolls
  • Edgers
  • Structural Grooved

Medium Size Rolls
(<10 ton final mass) (monobloc static cast)

  • Medium sections / Bar / Rod Mills
  • Edgers

Small Section Rolls
(<2 ton final mass) (monobloc static cast)

  • Rod / Bar Mills
