Abstract (en)

The invention describes a tap hole measuring device for a BOF vessel used in steel production, the BOF vessel (1), comprising an internal refractory lining (3) and a tap hole (2), which includes an opening (5) and a flange (4) with a planar surface. The measuring device comprises a movable monitoring car (7), a steel rod (8) with a fan-shaped metal washer (9) mounted on one end of the rod (8), the other end of the rod (8) being fixed in a releasable manner in a tubular coupling sleeve (10) of the movable monitoring car (7) and a laser measuring device (11) placed in the vicinity and aligned parallel to the rod (8) on the movable monitoring car (7). The present invention is also related to a method for measuring the thickness of a refractory lining in a tap hole (2) of a BOF vessel (1) using the tap hole measuring device.
