Double Poured Indefinite Chilled Rolls Manufacturers (DPIC Rolls)

Double Poured Indefinite Chilled Rolls Manufacturer

We are designated as one of the top most major Double Poured Indefinite Chilled Rolls manufacturers in India. Customised to clients requirement assuring the best quality which is used in TMT Rolling Mill, Rebar Rolling Mill, Wire Rod Rolling Mill, Finishing Stand, Intermediate Stand.

DPIC rolls are made of a high alloy iron shell, a soft grey iron or ductile iron core metal. These rolls are used in finishing stands of rod mills and for flat rolling. The shell material consisting of predominantly Bainitic or Martensitic matrix with free carbides with small quantities of tiny flake graphite have excellent wear resistance coupled with resistance to fire cracking. These rolls are available in the hardness range of 70 to 85 Shore C. The core material of these rolls is mostly grey iron but where higher strength is required, the core is made of ductile / nodular cast iron.

These Rolls are made of a high alloyed shell iron and a soft grey iron or ductile iron core metal depending on neck strength requirement. The shell material consists of predominantly Bainitic or Martensitic matrix with free carbides with small quantities of fine flake graphite, which imparts excellent wear and abrasion resistance coupled with resistance to fire cracking. These rolls are cast both through centrifugal and static route.
