Definitions
- the present invention relates to a device for carrying out a rapid repair of the cupboard of a blast furnace at the footprint of the tap hole of this blast furnace.
- the present invention proposes to provide means for solving the problem thus posed.
- the present invention therefore relates to a device for ensuring rapid repair of a blast furnace cupboard at the footprint of the taphole, characterized in that it comprises on the one hand a ferrule made of material consumable intended to be fixed on the nose of the capper, by crushing on the cupboard of the blast furnace at the level of the taphole during capping and on the other hand a piece of refractory material which is preformed inside the ferrule so as to be crushed on the cupboard by the capper and to adhere to the surface of the cupboard thus constituting a protective refractory lining and relining.
- the ferrule may optionally include notches intended to ensure its attachment to the nose of the capper. These notches preferably have an oblong shape.
- the material constituting said refractory piece is a flexible material, carbonaceous and quick cooking.
- FIG. 1 is a side elevational view of a first embodiment of a ferrule forming part of the device according to the present invention
- FIG. 2 is a view similar to Figure 1 illustrating a second embodiment of the shell of the device object of the invention
- FIG. 3 is a vertical axial sectional view of the refractory material placed in the shell of the device according to the invention and;
- FIG. 4 is a view in vertical axial section of the device according to the invention comprising the embodiment of the shell illustrated in FIG. 1.
- the device which is the subject of the present invention is designed so as to ensure rapid repair of the cupboard of a blast furnace at the level of the imprint of the tap hole of the latter.
- This device essentially comprises two parts:
- FIGS. 1 and 2 On the one hand, a ferrule made of consumable material, two examples of which are shown in FIGS. 1 and 2 and; - on the other hand, a piece of refractory material 'positioned in the shell and which has been shown in FIG. 3.
- the shell 10 is frustoconical and it is designed so as to come crashing on the cupboard of the blast furnace at the tap hole during capping.
- the shell 10 ′ has the same characteristics as
- the refractory part 14 placed in the shell 10 or 10 ′ has been shown in FIG. 3. It has a frustoconical external shape and it is provided with an axial bore as illustrated in FIG. 3. This part
- 20 14 is made of a flexible, carbon-resistant, quick-cooking refractory material. It is preformed so that it can be placed inside the shell 10 or 10 '. For this purpose, the values of its outside 1 and inside 2 diameters are determined so that this
- refractory piece 14 is positioned precisely inside the shell, as shown in FIG. 4.
- the internal walls of the bore of refractory piece 14 f have an inclination of 45 ° compared to
- the ferrule assembly 10 As stated above, the ferrule assembly 10 or
