Continuous casting is a modern and advanced technology of steel production, whose product is a steel blank as a semifinished product for further manufacturing. It is known that better monitoring and process control of casting improves the steel quality and is able to ensure customers’ requirements in terms of sizes, brands, quantities and properties with lower costs. The crystallizer belongs among the most important parts of this whole process [1]. At present many methods for analysing of the crystallizer temperature profile in operation were published and experimentally verified. In these methods, the thermocouples or Bragg gratings are widely used. New sophisticated analysis method of crystallizer temperature profile is the utilization of the optical fiber DTS based on the stimulated Raman scattering. This paper describes the first experimental measurement and verification of the method, which are necessary for the method deployment into the industrial practices.
