Slag discharge amount estimation method

Abstract

In a slag discharge amount estimation method, images of a slag flow flowing out from an outlet of a refining vessel are captured with a single imaging device. An upstream side of the slag flow is wider than a downstream side. Widths of the slag flow are found from the captured images, and a volume flow rate or mass flow rate of the slag flow is found. On the basis of the volume flow rate or the mass flow rate, a slag discharge amount is estimated.
