Abstract

Continuous casting is a modern and advanced technology of steel production, which product is a blank as an intermediate product for further processing. One of the most important parts of this whole process is crystallizer. At present most of methods, describing how to analyze the temperature profile of crystallizer in operation, were published and experimentally verified. These methods include the use of thermocouples or Bragg’s grids. New sophisticated method of analysis of crystallizer temperature profile is the use of optical fiber DTS based on stimulated Raman dispersion. This paper contains the first experimental measurement and method’s verification, which are necessary for the deployment this method into industrial practice.
