Revamping of Existing RCM to “Hyper UC-Mill” (Room 307)

Demands for electrical steel and high-strength steel products are growing rapidly worldwide because of the increasing needs of vehicle electrification, energy-efficient vehicles, etc. The HYPER UC-MILL is a well-suited solution to cold roll such harder and thinner materials with high quality and high productivity by utilizing smaller work rolls driven by a work roll drive system. The world’s first revamp of a reverse cold mill (RCM) to the HYPER UC-MILL was successfully completed with reliable technologies and precise construction work. This paper introduces the effects of the revamping to the HYPER UC-MILL by comparing the actual rolling data before and after the revamp.
