Indefinite Chilled (IC) Cast Iron Rolls

Vimco Rolls Pvt Ltd is proud to be recognized as the best Indefinite Chilled IC Rolls manufacturer in India, delivering high-performance rolls that meet the demanding needs of modern rolling mills.

Indefinite Chilled Cast Iron (IC) Rolls are static cast and feature a controlled hardness gradient within the working layer. Their microstructure can range from pearlitic to bainitic or martensitic, depending on the alloy content and cooling conditions. By adjusting the chemical composition, Vimco Rolls achieves the perfect balance of graphite and carbides, ensuring the desired hardness and optimal wear resistance. These rolls are a significant upgrade over Normal IC and Clear Chill IC Rolls. The presence of flake graphite in the matrix enhances their resistance to wear, spalling, and fire cracking, making them ideal for rolling products that demand a superior surface finish. To maintain their performance and prolong service life, adequate water cooling is essential during operation. When it comes to quality, consistency, and advanced metallurgy, Vimco Rolls is your trusted choice as the best Indefinite Chilled IC Rolls manufacturer in India.
