This article presents the successful commissioning of the world's first twin-stand HYPER UC-MILL for producing high-permeability non-grain-oriented electrical steel and advanced high-strength steel. The reversing mill features a newly developed small work roll diameter 6-high configuration equipped with driven work rolls and high-torque MH spindles, providing exceptional reduction capability and precise shape control. Induction strip heating, Minimum Quantity Lubrication, and an advanced strip-temperature prediction and guidance system enable stable thin-gauge rolling with high yield and minimal waste. The HYPER UC-MILL's compact work-roll design, reduced edge loading, and efficient torque transmission establish it as a benchmark technology for both new installations and cost-effective modernizations, ensuring reliable production of high-grade electrical steels and ultra-thin cold-rolled products.
