<p>The disclosure pertains to an arrangement for cooling a heated workpiece, such as strip or slab as it issues from a rolling mill or continuous slab caster. The longitudinally moving workpiece is caused to pass between a number of coolant discharge headers arranged above and below the workpiece in which, during its cooling, the cooling tendency of the upper and lower surfaces of the workpiece differ. The effective discharge of the coolant headers is varied to equalize the cooling rates of the upper and lower surfaces of the workpiece to symmetrically cool the workpiece.</p> |
