  • Method for the production of a steel strip by the casting of a strand followed by rolling
    Patent number: 5479982
    Abstract: A method for producing a steel strip which has been cast as a stand in a cooled oscillating continuous chill mould, comprises squeezing the strand emerging from the chill mould until it has a first cross-sectional thickness (40-50 mm), followed by hot rolling the strand until it has a second cross-sectional thickness (2-25 mm). Deviations in the normal path of travel of the strand following hot rolling are corrected by adjusting the thickness to which the strand is subjected during the first squeezing step.
