Abstract

1485878 Replaceable run-off for refractory lined vessel VEITSCHER MAGNESITWERKE-ACTIEN-GES 20 Dec 1974 [20 Dec 1973] 55201/74 Heading F4B A steel-making refractory-lined converter 1 has a replaceable outer, run-off comprising a block of refractory material 12 which is mounted in the converter side wall 1 by means of a metal holder 11 detachably secured to the converter side wall 1. As shown ramming mass packing 13 is interposed between the block 12 and the holder 11. When the original hollow bricks 9 are worn to the passage indicated by reference 8, a new run-off is bolted on. Secured to a cover 14 of the run-off is a plate 15 from which a metal tube 16 extends into the tapping passage. Repair ramming mass 17 is applied to fill the gap between the tube 16 and the worn boundary 8. The tube 16 melts shortly after pouring commences.
