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.

Abstract: A multi-partite guide roll which is especially usable in continuous casting installations has a plurality of axially arrayed discrete roll sections which are connected by stems so that they are compelled to rotate jointly about a common axis. The stems may either be provided at one axial end of the respective roll sections and extend into an axial recess of an axially adjacent roll section, or the roll sections may each have axial recesses at their opposite axial ends and the stems may be separate elements having two end portions each received in the axially aligned recesses of two axially adjacent roll sections.
