Abstract
A tuyere stock removal device is presented which is particularly well suited for use in conjunction with those types of shaft furnaces having a hot air, closed circuit pipe line which runs a circular course around the bosh. The tuyere stock removal device is suspended by means of rollers on rails and forms an integrated mechanical unit with the hot air, closed circuit pipe line. The present invention will perform all of the handling operations necessary for the dismantling and reinstallation of the blast nozzle and pipe bend as well as the tuyere and any slanting down pipe associated therewith.
