ABSTRACT:
A steel refining system has a crucible having an upwardly open mouth and containing a steel melt covered by slag, an oxygen lance directed downwardly into the mouth at the melt, a hood fitting downwardly over the mouth and having a hood wall formed by a multiplicity of coolant tubes, and an arrangement for circulating a coolant through these tubes. The tubes form a tubular hood-wall extension that has an outer end and is centered on an axis trained on the melt on the crucible. A holder is mounted on the outer end of this extension and contains a sound transducer carried by the holder and directed along the axis at the melt. A circuit is connected to this transducer for determining slag thickness by means of the sound detected by the transducer. The holder itself comprises a circularly annular hollow cell fixed by means of a collar to the extension and a transducer housing that is fixed to this cell and therethrough to the extension. The cell defines a passage aligned with the axis and is connected to a separate coolant circuit to prevent overheating of the transducer.
