  • Patent number: 4336925
    Abstract: The device permits the fixing of a stave plate to the armour shell of the blast furnace by means of a washer and a cup-shaped ring which are welded externally both to the shell and to protecting sleeves for inner water circulating tubes which are extended to outside the shell.The sealing is achieved by the interposition under compression of a preformed flexible apertured rectangular joint element and a preformed circular joint element of silicone elastomer or like plastics material, between the shell and the stave plate with adhesion on the bearing faces. It is completed by an injected mass and an annular joint element between the water circulating tubes and the corresponding protecting sleeves.The device is completed by the provision of packing products respectively between the inner wall of the shell and the stave plates and in gaps between two adjacent stave plates.
