Abstract
The invention concerns cooling apparatus for strip metal of the kind comprising a series of spaced cooling rolls around which the strip metal is passed such that it follows a serpentine path and is cooled by contact with the rolls, and elongate gas jet devices disposed widthwise of the strip opposite the outer surface parts of respective cooling rolls in contact with the strip. The invention is characterized in that each said gas jet device is partitioned into segments in said widthwise direction, in that each segment is provided with a gas flow control valve, in that means are provided at least at one cooling roll position for detecting strip temperature across its width, and in that strip temperature control and arithmetic means are provided to which the gas flow valves and the temperature detecting means are electrically connected, the arrangement being such that the temperature difference between the average temperature across the strip and the temperature of the strip at each segment width position can be compared, via electrical signals from the temperature detecting means and, if the temperature difference at a widthwise position is above or below predetermined limits, the c…
