The Development of VICTURA? Rolls for Hot Strip Mill Late Finishing Stands

摘要

Hot Strip Mill rolling (Conventional Mills, Compact Strip Mills and Steckel Mills) operations have been waiting for improved roll solutions that minimize required roll changes, which impact productivity and mill stability. Enhanced Indefinite Chill rolls were first introduced back in the mid-1990s. Recent alloy developments have resulted in improved wear characteristics by bringing together technologies of the iron based Indefinite Chill graphite, iron carbide and matrix morphology combined with tool steel based carbides. The enhanced metallurgical properties are characterized, as are the results and benefits of the extended mill performances achieved. Hot strip mills are realizing improved Total Cost of Ownership (TCO) through the transition of their entire roll inventories to these break-through products.
