    摘要: A casting of metal strip by continuous casting in a twin roll caster is provied. In a twin roll caster, molten metal is introduced between a pair of counter-rotated horizontal casting rolls that are cooled so that metal shells solidify on the moving roll surfaces. The twin roll caster is capable of continuously producing cast strip from molten steel through a sequence of ladles positioned on a turret. In casting thin strip by twin roll caster, the crown of the casting surfaces of the casting rolls varies during a casting campaign. The crown of the casting surfaces of the casting rolls in turn determines the strip thickness profile.

    摘要: A metallic strip edge flatness monitoring system for a rolling mill comprises one or more thermal imaging devices (105) arranged to monitor temperature or temperature variances across at least one region of interest (108, 115) in the rolling mill. The monitored temperature or temperature variances are input to a flatness control system (107) and a control signal (122) is generated in the flatness control system to modify actuation of actuators (106) in the rolling mill. The region of interest (108, 115) has a width (125) of less than half the width (126) of the metallic strip (101) and comprises a region on each side of the strip. The total width monitored is less than half the total width (126) of the metallic strip.
