Pearlitic Ductile Iron Roll II (SGPII) for Intermedium Mill

Pearlitic ductile iron roll II is a pearlitic ductile iron roll used in the intermediate rolling mill. The SGPII roll has high strength and toughness, can withstand high pressure and impact load, and is not prone to breakage or deformation, ensuring the stability of rolling. It is suitable for intermediate rolling mills and can meet the rolling needs of metal blanks of different sizes and materials. The cold hardness requirements are high. The SGPII roll can maintain good hardness and shape stability at high temperatures to ensure the size of the rolled products. Accuracy. SGPII rollers can improve the production efficiency of the intermediate rolling mill, and reduce downtime during the production process and the frequency of roll replacement, thereby reducing production costs. SGPII rollers are widely used in intermediate rolling mills and play an important role in the metal processing industry due to their advantages such as wear resistance, high strength, good cooling and hardening properties, and cost-effectiveness.

Hardness HSD: 55-65
Nickel composition %: 2.01-2.5
