  • Differential quench method and apparatus
    Patent number: 6557622
    Abstract: Surface defects in rolled steel are remedied by quenching a surface layer of the steel product downstream of the caster and upstream of the reheat furnace by transversely differentiated quenching to match the transverse temperature profile of the steel product. The flow rate of the quench spray is differentially adjustable across the width and optionally the length of the steel product. An array of spray nozzles controlled in transversely or longitudinally arranged groups provides the quench spray.
    Type: Grant
    Filed: February 19, 2002
    Date of Patent: May 6, 2003
    Assignee: IPSCO Enterprises Inc.
    Inventors: William R. Frank, Jonathan Dorricott, Laurie E. Collins, Joseph D. Russo, Robert J. Boecker, Brian H. Wales

  • Differential quench method and apparatus
    Patent number: 6374901
    Abstract: Surface defects in rolled steel are remedied by quenching a surface layer of the strand immediately downstream of the caster by transversely differential quenching to match the transverse temperature profile of the strand. The flow rate of the quench spray is differentially adjustable across the width and optionally the length of the strand. An array of spray nozzles controlled by groups provides the quench spray.
