ABSTRACT:
A shaft furnace has a refractory lining within its armour and cooling plates located in recesses in the lining. In order to make it easier to remove and replace the cooling plates and to improve heat transfer, it is now proposed to construct the recess walls of special shaped members so that the recess retains its shape. The shaped members include elongate side members, a cover member resting on the elongate members, a bottom member below the elongate members and a front member between the front edge of the cooling plate and the furnace interior. Copper sheets may be provided between the cooling plate and these shaped members.
