Abstract
Reheat furnaces for steel mills are constructed using resilient supporting mechanisms for restraining and supporting the binder structure within a rigid steel frame. This construction enables the furnace to be rebricked without affecting other furnaces in the battery and also allows the refractory lined wall to distort without disturbing the rigid frame.
Claims7
A reheat furnace comprising:
- a rigid frame;
- upright wall means defining a refractory element lined cavity disposed within said frame, said wall means including a binder structure between said refractory elements and said frame for limiting the relative movement of said refractory elements with respect to each other;
- resilient means engaging said rigid frame and said binder structure for movably supporting said binder structure and resiliently urging said binder structure inwardly of said cavity, said resilient means being yieldable to accomodate deflection of said binder structure toward said frame without overloading the latter;
- and
- sheild means disposed above said resilient means for protecting said resilient means from debris;
- said shield means comprising a pair of shield members, one of said shield members being mounted on said frame and the other of said shield members being mounted on said binder structure, said shield members extending toward each other and overlapping with clearance therebetween so as to maintain protection of said resilient means during deflection of said binder structure even when said binder structure is not parallel to said frame.
