    专利说明:

    The invention relates to pechestroeniyu, specifically to seals to prevent knocking of gases at the electrodes of electric melting furnaces.
    Seals are known for preventing the knocking out of gases at electrodes of electric furnaces, including a box-type device with water cooling and without cooling with various placement options relative to the roof tlj. The disadvantage of such devices is the lack of tightness between the electrode and the roof of the furnace, since in the design of the electrode and during its movement, there is a violation of the 15 ratio of the geometric dimensions of the electrodes of the sealing device. Sealing devices do not provide compensation for changes in the geometric dimensions of the electrode. 20
    A device for bypassing electrodes is known that has the ability to compensate for changes in geometric dimensions, consisting of a housing in the form of a box-shaped device and annular 252 hoses, into which a medium expanding them is supplied under pressure1 [2].
    A disadvantage of the known device is the low degree of compaction at the points of contact with furnace parts.
    The purpose of the invention is to increase the tightness.
    This goal is achieved in that the device containing the box-shaped device, inside of which ring hoses are placed, is equipped with sealing elements made with the possibility of movement perpendicular to the vertical axis of the electrode.
    The lower sealing element is provided with heat-resistant thermal insulation, and its end part in contact with the electrode is provided with protrusions whose inner diameter corresponds to the outer diameter of the electrode.
    The upper sealing element made in the form of layers of elastic tape and U-shaped elements interconnected! ·. 934,920 4
    A layer of electrical insulating material is installed between the box-shaped device and providing continuous sealing connection with the upper part of the furnace roof.
    The drawing shows a device 5, a section along the vertical axis of the electrode.
    The device comprises a furnace vault 1, an electrode 2, a connecting ring 3, a box-shaped device 4, an electrical insulating layer 5, a lower sealing element 6 with two protrusions 7, which can be made in the form of rods, the inner diameter of which must correspond to the diameter of the electric 15 yes, hydraulic heat resistant w ^ eng
    8, heat-resistant insulating material
    9, for example kaolin-based cotton, a box cover 10, an annular recess 11 for a second 20 hydraulic hose 12, which acts on the elastic band 13 by means of V-shaped elements 14, a gap 15 between the sealing element and the inner wall of the box device 25 ,
    During vertical movements of the electrode may cause the horizontal deflection, which can cause seal failure ka electrode 30 connected a butt-seal device. To eliminate this probability, the sealing element 6 is maintained at a pressure of 0.5 “5 bar in the heat-resistant hydraulic hose 8. will strive to continuously maintain strong contact with the electrode 2. To give freedom of movement of the sealing element relative to the electrode, a gap of 15 is provided. The degree of sealing of the electrode by the upper sealing element depends on the pressure in the hose 12.
    The presence of two systems for compensating the horizontal displacements of the electrodes, and the sealing of the electrode with sealing devices, makes it possible to increase the tightness of the unit for introducing electrodes into the smelting furnace.

The drawing shows the device, a section along the vertical axis of the electrode. Usurastao contains furnace roof 1, electrode 2, connecting ring 3 box-shaped device k, electrically insulating layer 5 lower sealing element 6 with two protrusions 7 which can be made in the form of rods, the inner diameter of which should correspond to the diameter of the electrode, hydraulic heat-resistant 8, heat-resistant insulating material 9, for example kaolin-based cotton wool, a cover 10 of a box-shaped device, an annular recess 11 for a second hydraulic hose 12 that acts on the elastic band 13 with V-shaped elements I, the gap 15 between the sealing element and the inner wall of the box-like device. During vertical displacements of the electrode, horizontal deviations may occur, which may cause a leak in the joint tightness of the electrode-sealing device. To eliminate this possibility, the sealing element 6, while maintaining the pressure in the hydraulic heat-resistant hose 8 at a level of 0.5 to 5 bar. will continuously maintain strong contact with electrode 2. To impart freedom of movement of the sealing element relative to the electrode, a gap 15 is provided. The degree of sealing of the electrode by the upper sealing element depends on the pressure in the hose 12. The presence of two systems for compensating the horizontal displacements of the electrodes. 9 04 providing continuous sealing of the electrode with sealing devices, allows to increase the tightness of the electrode insertion unit into the smelting furnace. Claim 1.
