An Application research of Colorimetric Temperature Measuring in Steel Billet of Heating Furnace

At present, there is a common usage of adhering temperature recorder like black box to the surface of steel billet in the iron and steel Industry. After the heating process we can get the data and then analyze the heating process and establish a heating model of it. However, it's not easy to upmost the controlling in the practical application, this article use the full view real-time monitoring technology by applying a heat tracking precision instrument to monitor the temperature of the surface of inner steel billet, so we can get billet surface temperature distribution data through real-time online monitor and handle the image of the surface, then send the temperature distribution to the optimized control system and realize optimization control of the furnace temperature.
