Current Research Status of Contact Type High-Temperature Molten Steel Continuous Temperature Measurement Sensors
摘要
Abstract
In continuous casting production,the temperature of molten steel in the intermediate ladle can affect the quality of casting products and production energy consumption,so the temperature monitoring of molten steel is crucial and become a research hotspot in recent years.First,based on the type of sensors,the in-situ continous contact type temperature measurement technology of thermocouple and black body cavity for molten steel are introduced.The optimization of thermocouple temperature measurement sensor in sensor preparation process,measurement error and temperature compensation is reviewed.The improvements of the black body cavity temperature measurement sersor in the simulation model,sensor stucture,protective wall and thermal ra-diation signal processing angle are described.Detailed exploration is conducted on the erosion and thermal shock faults mechanisms encountered in the practical application of temperature sensors for molten steel.Based on the mechanisms of erosion and thermal shock faults,a series of feasible solutions are summarized to enhance the resistance of sensors to erosion and thermal shock,which can provide reference and guidance for research-ers in the research direction of in-situ continuous temperature measurement of molten steel.关键词
