Monitoring Liquid Level of Blast Furnace Hearth and Torpedo Ladle by Electromotive Force Signal

Abstract: The state of a blast furnace hearth, especially the liquid level of hot metal and slag during the tapping process, is of crucial importance with respect to a long campaign blast furnace. In practice, the state of the hearth is evaluated mainly by the experience of operators. In this paper, the electromotive force (EMF) is used to monitor the liquid level of a laboratory scale of blast furnace hearth and the effect of liquid level, EMF sensors position and the thickness of refractory on EMF signals are tested u… Show more

“…Since the results of the model clearly improved as the parameter controlling the declivity of the slag surface was changed, another development would be to recursively estimate the parameter by minimizing the (slag) corrections with respect to it. The options to consider pools of varying size are also worth exploring, as well as the possibility of incorporating indirect level information, such as emf signals, to improve the prediction accuracy of the model …”
