| Abstract Scope |
A laboratory scale experiment was performed using a graphite crucible containing cryolitic bath with chemistries and temperature corresponding to industrial aluminum smelters conditions. A series of industrial K-type thermocouples with various diameters were immersed simultaneously in the cryolite to measure bath temperature continuously. During that time, the bath temperature was periodically measured using Heraeus Electro-Nite’s Fiberlab® equipment and Positherm® probes. This experiment allowed the comparison of temperature variations between different methods and conditions in order to define the response time of different devices and their uncertainty levels. Under the same experimental conditions, liquidus temperature measurements were performed using differential thermal analysis (DTA) between K-type and S-type probes attached to sampling cups as well as the Heraeus Electro-Nite’s Fibercup ® technology. Such results are presented at the accuracy of the methods are discussed. |
