    DESCORIATE DOOR FOR OVEN AND ASSOCIATED OVEN
    D E S C R I P C I O N
    5 OBJECT OF THE INVENTION
    The present invention can be included in the technical field of furnace desalting doors, which are used to periodically remove slag, as well as for other activities, such as additive loading, sample collection, measurement temperature, the insertion of carbon and oxygen by injectors, and also to inspect the interior of the oven.
    The object of the invention is an oven slag door in which the dimensions thereof are very small, so that the space available on the front of the door is increased when the panel carrying out the scratching of the Materials deposited inside the oven, near the door, are arranged inside the oven. In addition, when the door is closed, no part of the door protrudes above the furnace tank, facilitating the introduction of scrap metal, and when it is open, it allows an opening with a great amplitude, which facilitates the extraction of slag.
    BACKGROUND OF THE INVENTION
    In steel production cycles using scrap and / or metal raw material HBI 25 (hot briquetted iron ”), CDRI (cold direct reduced iron” acronym, reduction direct cold iron) / HDRI (acronym for "hot direct reduced iron") for the regeneration and obtaining of new steel, the core of this secondary steel fabrication is the arc furnace electric (EAF, acronym in English of "electric arc furnace"), in which the metal 30 mentioned in said furnace melts.
    Said electric arc furnace basically comprises a cell or vat, composed of a crucible for collecting molten steel, a roof covering also known as an open vault, three electrodes that go down through the roof, elements for supply
    of chemical energy and a smoke extraction system. The electric arc furnace has a slag door that is normally located on the vertical wall of the furnace stack in communication with the interior of the oven through a tunnel. Said slag door is used to periodically remove the slag, as well as for other 5 activities, such as additive loading, sample collection, temperature measurement, carbon and oxygen insertion by injectors, and also to inspect The interior of the oven.
    Among the above is the European patent EP2399094B1 relating to a door of 10 slag for an electric arc metallurgical furnace comprising a movable lower slag removal panel operated by an actuator and a movable upper panel that can be opened to make observations and interventions in the molten metal, where the upper mobile panel and the lower mobile panel are placed in front of a tunnel that gives access to a crucible and placed in front of the slag door to close the aforementioned tunnel.
    fifteen
    Said panels are aligned vertically, where the upper panel is inclined outwards and can move itself out of the oven and upwards, while maintaining said inclination with respect to the wall of the oven, while the lower panel leads to carry out partial elevation and partial lowering movements, partial advance 20 inside the oven and partial recoil of the oven, both for the removal of the slag present in the oven crucible, and for pushing various materials into the oven interior, in which the actuator that drives the lower panel is connected to it by means of a parallelogram lever formed by a plate secured to said lower panel, so that said lower panel can perform a cycle of movements upwards, towards the interior of the oven, downwards in contact with the slag, and move away from the oven to remove the slag, the aforementioned cycle can be repeated several times until the complete removal of all the slag and finally ending with the closure of said lower part of the tunnel entrance.
    It is also known the European patent application EP2489971A1 relating to a furnace dessoriating door comprising a movable upper panel in a mounted state of the door, from an opening position, in which the upper panel is remote and above an opening slag discharge, to a closed position, in which the upper panel covers the upper part of said slag discharge opening, in addition to a panel
    movable bottom, in a mounted state of the door, from an open position, in which the lower panel is removed from a slag discharge opening, to a closed position, in which the lower panel covers at least part of said opening slag discharge, wherein the lower panel is part of an extralble sliding telescopic mechanism configured to push the lower panel through said slag discharge opening into an associated furnace and pull the lower panel back again.
    However, the aforementioned furnace door mentioned above occupies a large vertical space, since to carry out the movement of the upper panel, 10 comprises rails through which the door rises and falls, greatly exceeding the height by above the tank, even when the door is closed, which makes the tasks of introducing scrap difficult. In addition, the guidance by rails causes misalignment problems, which can lead to offsets of the door with respect to the opening and blocking of them by dirt, requiring continuous lubrication and maintenance. fifteen
    The furnace slag door of the present invention solves all the above drawbacks.
