High Strength Pearlitic Ductile Iron Roll I (SGPI) for Roughing Mill

Pearlite ductile iron rolls have high strength and toughness, can withstand high pressure and impact loads, and are not prone to breakage or deformation, ensuring the stability of rolling. Pearlite ductile iron roll I is suitable for rough rolling mills and can meet the rough rolling needs of metal billets of different sizes and materials, including steel billets, aluminum billets, etc. Compared with some more expensive roll materials, pearlitic ductile iron rolls have lower manufacturing costs, but their performance can still meet the requirements of roughing mills and are cost-effective. Pearlite ductile iron rollers can improve the production efficiency of the roughing mill, and reduce downtime during the production process and the frequency of roll replacement, thereby reducing production costs. Due to its wear resistance, high strength, good chilling and hardening properties, and cost-effectiveness, it plays an important role in roughing mills and is widely used in the metal processing industry.
