Abstract

An apparatus and method for viewing and analyzing the interior of a molten metal bath during treatment in a metallurgical vessel comprises a concentric pipe tuyere extending into an open mouth of the vessel and below the surface of the bath and comprising an inner pipe through which a pressurized transparent fluid is passed, and an outer pipe forming, with the inner pipe, an annulus through which a cooling fluid is passed. A sight glass is disposed in alignment with an opening in the inner pipe and with a centerline of the tuyere providing visual access to the interior of the bath. An optical sensor is associated with the sight glass to receive and analyze light generated in the bath to determine molten metal properties such as temperature and chemical composition.
