Discussion on the measurement method of surface temperature of steel billets in heating furnace
This article introduces the conventional thermocouple and radiation measurement methods for the surface temperature of steel billets in a heating furnace,as well as their shortcomings.In response to the problem that measurements such as buried thermocouple and black box are only suitable for steel bil-let heating testing and cannot meet the continuous measurement of the steel billet heating process,a method for continuous temperature measurement by embedding thermocouple in the heat-resistant pad of a walking beam heating furnace is proposed.Based on the length of steel billet movement and the tempera-ture values of steel billets at each measuring point of the pad,Build a temperature change model during billet heating to achieve prediction and tracking of the surface temperature of the billet.
