| Abstract Scope |
The heat transfer ability of the mold flux is crucial for balancing the heat flux between the slab and mold. The double hot thermocouple technology (DHTT) is widely used for the qualitative determination of the heat transfer performance of the mold flux due to its advantages of rapid in-situ testing. However, the traditional DHTT cannot determine heat flux quantitatively, which limits the development of DHTT in the field of heat transfer measurement. In the current study, the in-situ quantitative investigation method based on DHTT was, for the first time, proposed to determine the heat transfer performance of mold flux. Herein, the heat flux of three mold fluxes with different Al2O3/SiO2 (A/S) ratios was estimated by using the new DHTT. The result showed that the heat flux decreases with increasing A/S ratio, which is consistent with the result of the parallel-sided plate method. |
