Single Pour Solid Chill Rolls

Single Pour Solid Chill Rolls are cast iron rolls manufactured in a single pour process with a chilled outer working layer and a grey iron core. The outer surface is rapidly cooled during casting to create a hard, wear-resistant "chill zone," while the inner structure remains softer and more ductile. This results in a roll with excellent surface hardness and good mechanical strength, ideal for a wide range of general-purpose rolling applications.

These rolls are known for their uniform hardness, good thermal conductivity, and cost-effectiveness. They are best suited for mills that require consistent surface finish and durability without the added complexity or cost of composite rolls.

  • High surface hardness (40–70 HSD) with gradual transition to a softer core
  • Cost-effective and reliable for general-purpose use
  • Good thermal shock resistance and surface wear performance
  • Uniform microstructure with minimal cracking risk
  • Available in various diameters, lengths, and hardness levels

Single Pour Solid Chill Rolls are widely used in various rolling mills where moderate rolling loads and surface wear are expected. They are particularly effective in:

  • Re-Rolling Mills – Rolling of mild steel, structural bars, and flats
  • Light & Medium Section Mills – For channels, angles, and small profiles
  • TMT Bar Mills – Suitable for early stands in the roughing stage
  • Wire Rod Mills – Applied where consistent dimensional accuracy is required
  • Sheet and Strip Mills – Used for rolling thin sections with surface finish demands
  • These rolls offer a dependable solution for mills seeking durability, simplicity, and cost-efficiency in their rolling operations.
