All back up rolls manufactured by JSW M&E are forged steel products. Compared with cast steel products, forged rolls have high fatigue strength and spalling resistance. All users in Japan use forged back up rolls at present. JSW M&E has high ability to manufacture "huge" and "high quality" steel products. Plate mill Back up roll (PB roll) is no exception. JSW M&E can manufacture heavy PB rolls by forging. In addition, JSW M&E can manufacture high-Carbon-Cr-Mo steel that obtains good combination of both high wear resistance and high resistance to thermal shock cracking that lasts until the scrap diameter.
