METHOD AND DEVICE FOR SURFACE TEMPERATURE MEASUREMENT OF CAST SLAB ON CONTINUOUS CASTER

摘要

PROBLEM TO BE SOLVED: To measure an accurate surface temperature of a cast slab using a radiation thermometer without disturbance of moisture, when measuring surface temperature of the cast slab in a continuous caster being continuously cast.;SOLUTION: When surface temperature of the cast piece 11 in the continuous caster is measured using the radiation thermometer 12, spray of secondary cooling water from a spray nozzle 5 to a temperature measuring zone of the cast slab surface is temporarily interrupted by activating an electromagnetic shielding valve 13. Thus, the surface temperature of the cast slab is measured by the radiation thermometer in the state of suppressing generation of steam caused by the secondary cooling water in the temperature measuring zone of the cast slab surface.;COPYRIGHT: (C)2009,JPO&INPIT
