Abstract

1432170 Tapping metallurgical converters CENTRO SPERIMENTALE METALLURGICO SpA 30 July 1973 [31 July 1972] 36115/73 Heading F4B A plug for a metallurgical converter tap hole comprises a cylindrical body stem 1a of refractory material having an enlarged cylindrical head 1b with a diameter larger than that of the tap hole and an annular packing B around the stem and adjacent the head is utilized of a material which is cold coherent, plastically deformable at higher temperatures and solidified at temperatures thereabove but below that of operation of the converter after an exposure period. The stem and head may be connected by a frusto-conical element of refractory material, and the packing may be retained in position by a metal sheet or like collar 1e provided along the lateral surface of the head.
