Abstract

THIS PAPER DESCRIBES THE SUCCESSFUL STARTUP OF THE WORLD’S FIRST TWIN-STAND HYPER UC-MILL DEDICATED TO PRODUCE HIGH-PERMEABILITY NON-GRAIN ORIENTED (NGO) ELECTRICAL STEEL AND ADVANCED HIGH-STRENGTH STEELS (AHSS). THE REVERSING MILL FEATURES A NEW GENERATION OF A SMALL DIAMETER 6-HIGH TECHNOLOGY WITH DRIVEN WORK ROLLS AND A HIGH-TORQUE MH-SPINDLES. FOR COLD ROLLING OF HIGH-GRADE ELECTRICAL STEEL, THE MILL IS ADDITIONALLY EQUIPPED WITH AN INDUCTION STRIP HEATING SYSTEM IN COMBINATION WITH MINIMUM QUANTITY LUBRICATION MQL AND AN INNOVATIVE STRIP TEMPERATURE PREDICTION AND GUIDANCE SYSTEM. OPERATIONAL HIGHLIGHTS WILL BE PRESENTED IN THE PAPER.
