Abstract

In a support construction for a hot blast main which is connected by respective branches to the outlets of a plurality of hot blast stoves of a blast furnace, the main is suspended on each stove by means of a rod system secured to a stiffened transitional region between the wall and dome of the stove and having an outer end located above the main. The main is suspended from this outer end, to which at least one strut extends from the stove wall adjacent the hot blast outlet. A travelling crane track is secured to the lower side of the rod systems so as to extend above valves incorporated in the hot blast branches. Thus these valves can easily be removed and replaced.
