Abstract
A main object of the present invention is to provide a method capable of measuring surface temperatures of a plurality of points of cast slab at a secondary cooling zone of a continuous caster with a good accuracy and at low cost. The method comprises the steps of inserting one end of a plurality of optical fibersrespectively to nozzlesand tubes, and installing each nozzle between support rolls that support the cast slab, while spraying purge air from each nozzle toward a surface of the cast slab, receiving a thermal radiation light from the cast slab at the one end of each optical fiber, gathering other ends of the optical fibersin a bundle to take images including a core image of the other end of each optical fibers by an imaging means, and calculating the surface temperature of the cast slab.
