- Online monitoring of the ladle stirring
- Xu, Xiaodong; Brooks, Geoffrey; Yang, William
- Gas stirring is commonly applied in secondary steel making and the objectives of stirring is to enhance heat and mass transfer inside the ladle to achieve homogenization of temperature and composition, facilitate slag-metal interactions, and accelerate the removal of inclusions in the steel, however, it is difficult to monitor the stirring effect using just the gas line pressure and the volume flow rate due to leakages between the connectors and hook-ups. An intermittent view of the top disturbed surface has to be applied to monitor the stirring conditions during the actual operations, in which, the subjective judgement of the operator is required to control the stirring process. Acoustic technology and vibration analysis to monitor and control steelmaking process have found increasing application in recent years. It has been found that the sound emitted during certain metallurgical operations reflects the corresponding operating conditions and thus the acoustic response may be used to monitor and control the process.Vibration detectors have been used to determine the degree of stirring in a ladle in industry. Stelco and Nupro Corporation have used vibration sensors on the wall of ladles as a basis for ladle control systems and positive results have been reported by using vibration analysis to control gas flow into the ladle. However, no investigation has been reported that combined all the signals simultaneously.
