  • Method for the in-line manufacturing of steel tube
    Patent number: 11519048
    Abstract: A method for manufacturing of steel tube from a long steel strip, including providing a length of steel strip material to the process, forming a tube of the steel strip material, welding the formed tube in longitudinal direction, giving the tube a heat treatment wherein the mentioned steps are performed in one continuous in-line manufacturing line and the heat treatment includes a heating regime such that in successive cross-sections of the tube a microstructure is achieved which holds at least 50 vol % austenite and a cooling trajectory to re-introduce ferrite, and/or bainite in desired volume fractions.
    Type: Grant
    Filed: July 13, 2017
    Date of Patent: December 6, 2022
    Assignee: TATA STEEL NEDERLAND TUBES BV

  • Process for the heat treatment of metal strip material
    Patent number: 9234255
    Abstract: Disclosed is a process for the heat treatment of metal strip material providing mechanical properties that differ over the width of the strip, wherein the strip is heated and cooled and optionally over-aged during a continuous annealing process. At least one of the following parameters in the process differs over the width of the strip: heating rate, top temperature, top temperature holding time, cooling trajectory after top temperature; or, when over-aging is performed, at least one of the following parameters in the process differs over the width of the strip: heating rate, top temperature, top temperature holding time, cooling trajectory after top temperature, over-aging temperature, over-aging temperature holding time, lowest cooling temperature before over-aging, re-heating rate to over-aging temperature. Also, at least one of the cooling trajectories follows a non-linear temperature-time path. Also disclosed is strip material thus produced.
