The blackbody cavity sensor for continuous temperature measurement of molten steel has been widely used in steel industry. However, due to the closed bottom of the inner tube, the temperature measurement accuracy is seriously affected. It’s urgent to redesign and improve the sensor, which involves multidisciplinary knowledge, including materials, heat and flow science. This paper first clarifies the relationship between sensor functional requirements and various physical structure parameters from the perspective of axiomatic design. On this basis, the virtual models of the blackbody cavity sensor are established, including geometry model, multi-physical field model, material physical properties and boundary conditions. And then through comparison between experiment and simulation, it is found that for the temperature measurement accuracy, the deviations between the simulation and the actual experimental result are less than 1.5℃. This verifies the accuracy of the virtual model.
