Online Analysis of Stirring Processes in Ladle Metallurgy

Gas stirring is commonly used in pyrometallurgical vessels to enhance mass and heat transfer and promote impurity removal. These processes can be difficult to monitor because of the severe operating conditions associated with these processes. However, experienced operators can make judgment of the process by observing the disturbance of the top surface and listening to the sound of the bubbling. In this article, we proposed a new approach of …
