Variation of Ladle Eye Size Using Image Analysis

Inert gas bubbling through purge plugs is used to stir molten steel in ladles to ensure compositional and thermal uniformity. The exposed bare steel at the surface is referred to as the "ladle eye." In this plant study, images were captured and analyzed. The variation in the ladle eye size throughout a heat was found to be large (up to 100%). The results show that dynamic measurement of the ladle eye is required to minimize argon usage and control the ladle eye effectively. Various measurement options of sound, image, and vibration are compared and evaluated.
