APPARATUS FOR SUPPORTING AND GUIDING AN AUXILIARY LANCE WHICH CARRIES OUT MEASUREMENTS AND/OR TAKES SAMPLES IN A METALLURGICAL FURNACE

摘要

To support and guide a sub-lance for a metallurgical furnace, a sub-lance carriage 3 and sub-lance guide 4 run on a track 1. The guide 4 is below the carriage and moves in dependence on the carriage movement for part of the carriage travel. To provide a simple means for control of the movement of the guide, the guide is suspended by a support 6, such as a cable, the top end of which engages the carriage but is caught by fixed stops 8 when the carriage moves below a certain point. The cable 6 is housed within a tubular guide 5 over part of its length.
