Abstract
A method of determining disturbances when discharging molten metal from a metallurgical container having an outlet into a receiving container. In steps of this process, a real time video image of the teeming stream is monitored to detect the presence of a slag phase, or conditions conducive to the presence of such a phase in steel being transferred, the monitored images are processed to provide data used to assess the quantity of slag passed, parameters of data generated representing characteristics of the teeming stream image are compared with threshold values to generate at least one signal indicative of the passage of slag, and the threshold values are progressively adjusted responsive to data collected by monitoring plural parameters of the teeming operation selected from predicted teeming duration, weight of the receiving vessel, condition of means controlling teeming rate, and oxygen content of the molten steel.
