Product Description
Double Poured Indefinite Chilled Rolls (DPIC)
D.P.I.C Rolls are made of a high alloy iron shell and 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 hardness range of 70 to 85 ShC. 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.
