ABSTRACT:
An arrangement for lining a blast furnace of varying inner dimensions includes a working platform which can be adjusted in its transverse dimensions to the inner dimensions of the blast furnace at any particular elevation of the same. The working platform is lifted to different elevations within the blast furnace by a plurality of tackles which are mounted on the working platform and at a region of the blast furnace which is located upwardly of the working platform. The working platform includes a central portion and a plurality of support elements which are mounted in the central portion for telescopic displacement relative thereto toward and away from the inner surface of the blast furnace, and a plurality of floor elements is interchangeably and detachably supported on the support elements when the latter are in their at least partly telescoped-out position. A conically downwardly diverging sleeve is located underneath the working platform and communicates with an opening of the working platform through which lining material is supplied to the latter.
