Abstract

Unidad de boquilla (1) que se utiliza en un dispositivo de cambio de boquilla (100) de un aparato de colada continua de metal. El dispositivo de cambio de boquilla (100) es del tipo que comprende una abertura de carga y medios de guía (7) para deslizar la unidad de boquilla a través de dicha abertura a la posición de colada con respecto al dispositivo de cambio de boquilla, donde dicha unidad de boquilla (1) comprende una placa de boquilla (1) hecha de un material refractario revestido en un recipiente de metal. A fin de impedir que dicha placa se presente a la abertura de carga con la orientación errónea, es decir, con el borde posterior (2d) primero, dicha placa está provista de al menos una aleta (6) en o adyacente el borde posterior (2d), siendo dicha al menos una aleta (6) transversal a dicho primer eje mayor (X1) y extendiéndose sustancialmente más allá del perímetro que define la base del prisma de manera que la abertura de carga (16) admite el acoplamiento de la base (2c, 2d) de la placa de boquilla (2) pero no de la al menos una aleta (6). El punto de pliegue flexural o fuerza flexural extrema de dicha al menos una aleta (6) está comprendido entre 10 y 2000 kgf (100 N y 20 kN), que es un valor demasiado alto para que un operador llegue a mano, pero que puede ser manipulado muy fácilmente por un brazo hidráulico, mecánico o neumático (31) que de ese modo puede doblar o romper dicha al menos una aleta (6) para empujar la placa a suposición de colada, sólo si está cargada con su borde anterior primero.Reivindicación 1: Unidad de boquilla (1), caracterizada porque es para usarla en un dispositivo de cambio de boquilla (100) de un aparato de colada continua de metal, siendo dicho dispositivo de cambio de boquilla (100) del tipo que comprende una abertura de carga y medios de guía (7) para deslizar la unidad de boquilla a través de dicha abertura a la posición de colada con respecto al dispositivo de cambio de boquilla, donde dicha unidad de boquilla (1) comprende una placa de boquilla (2) hecha de un material refractario parcialmente revestido en un recipiente de metal, teniendo dicha placa una forma inscrita en un prisma y estando definida por: a) un primer borde anterior (2c) y un segundo borde posterior opuesto (2d) que definen las bases primera y segunda del prisma, transversales a un primer eje (X1), siendo dichas bases preferentemente poligonales; b) una superficie de deslizamiento superior (2a) definidas por un eje primero y uno segundo (X1, X2) y una superficie de apoyo inferior (2b) que forma un primer par de caras de unión opuestas y paralelas del prisma; c) bordes laterales primero y segundo (2e) sustancialmente paralelos a dicho primer eje mayor (X1) que conectan las bases primera y segunda (2c, 2d) del prisma así como también el primer par de caras de unión opuestas (2a, 2b); d) un orificio de lado a lado (3) que conecta fluidamente la superficie de deslizamiento superior (2a) y la superficie de apoyo inferior (2b), desplazándose dicho orificio de lado a lado a lo largo de dicho primer eje (X1); y un conducto tubular (4) que comprende un orificio central (3a) en comunicación fluídica con el orificio de lado a lado (3) de la placa, estando fijado un extremo del conducto (4) a la superficie de apoyo inferior (2b) de la placa (2), abriéndose dicho orificio central (3a) al ambiente a través de al menos una abertura (5) localizada en o cerca del extremo opuesto del conducto tubular (4); donde se provee al menos una aleta (6) en o adyacente al borde posterior (2d), siendo dicha al menos una aleta (6) transversal a dicho primer eje mayor (X1) y extendiéndose sustancialmente más allá del perímetro que define la base del prisma, y en que el punto de pliegue flexural o fuerza flexural extrema de dicha al menos una aleta (6) está comprendido entre 10 y 2000 kgf (100 N y 20 kN). Reivindicación 11: Recipiente de metal (12) para revestir la placa (2) de una unidad de boquilla (1) de acuerdo con cualquiera de las cláusulas 1 a 5, caracterizado porque tiene una forma adecuada para revestir al menos una porción de todas las caras de la placa de boquilla (2) excepto la superficie de deslizamiento superior (2a), y comprende al menos una aleta (6) provista en o adyacente al borde posterior (2d), siendo dicha al menos una aleta (6) transversal a un primer eje mayor (X1) y extendiéndose sustancialmente más allá del perímetro que define las bases del prisma, y en que el punto de pliegue flexural o fuerza flexural extrema de dicha al menos una aleta (6) está comprendido entre 10 y 2000 kgf (100 N y 20 kN).Nozzle unit (1) used in a nozzle change device (100) of a continuous metal casting apparatus. The nozzle changing device (100) is of the type comprising a loading opening and guide means (7) for sliding the nozzle unit through said opening to the casting position with respect to the nozzle changing device, wherein said nozzle unit (1) comprises a nozzle plate (1) made of a refractory material coated in a metal container. In order to prevent said plate from being presented to the loading opening with the wrong orientation, that is, with the rear edge (2d) first, said plate is provided with at least one fin (6) on or adjacent the rear edge ( 2d), said at least one fin (6) being transverse to said first major axis (X1) and extending substantially beyond the perimeter that defines the base of the prism so that the loading opening (16) admits the coupling of the base (2c, 2d) of the nozzle plate (2) but not of the at least one fin (6). The flexural fold point or extreme flexural force of said at least one fin (6) is between 10 and 2000 kgf (100 N and 20 kN), which is too high for an operator to reach by hand, but can It can be handled very easily by a hydraulic, mechanical or pneumatic arm (31) that can thereby bend or break said at least one fin (6) to push the plate to the assumption of casting, only if it is loaded with its leading edge first. Claim 1: Nozzle unit (1), characterized in that it is for use in a nozzle change device (100) of a continuous metal casting apparatus, said nozzle change device (100) being of the type comprising an opening of loading and guiding means (7) for sliding the nozzle unit through said opening to the casting position with respect to the nozzle changing device, wherein said nozzle unit (1) comprises a nozzle plate (2) made of a refr material aquarium partially coated in a metal container, said plate having a shape inscribed in a prism and being defined by: a) a first front edge (2c) and a second opposite rear edge (2d) defining the first and second bases of the prism , transverse to a first axis (X1), said bases being preferably polygonal; b) an upper sliding surface (2a) defined by a first and a second axis (X1, X2) and a lower support surface (2b) forming a first pair of opposite and parallel joining faces of the prism; c) first and second side edges (2e) substantially parallel to said first major axis (X1) connecting the first and second bases (2c, 2d) of the prism as well as the first pair of opposite joining faces (2a, 2b) ; d) a hole from side to side (3) that fluidly connects the upper sliding surface (2a) and the lower support surface (2b), said hole moving from side to side along said first axis (X1); and a tubular conduit (4) comprising a central hole (3a) in fluidic communication with the hole from side to side (3) of the plate, one end of the conduit (4) being fixed to the lower bearing surface (2b) of the plate (2), said central opening (3a) opening to the environment through at least one opening (5) located at or near the opposite end of the tubular conduit (4); where at least one fin (6) is provided on or adjacent to the rear edge (2d), said at least one fin (6) being transverse to said first major axis (X1) and extending substantially beyond the perimeter defining the base of the prism, and in which the flexural fold point or extreme flexural force of said at least one fin (6) is between 10 and 2000 kgf (100 N and 20 kN). Claim 11: Metal container (12) for coating the plate (2) of a nozzle unit (1) according to any of clauses 1 to 5, characterized in that it has a suitable shape for coating at least a portion of all faces of the nozzle plate (2) except the upper sliding surface (2a), and comprises at least one fin (6) provided on or adjacent to the rear edge (2d), said at least one fin (6) being transverse to a first major axis (X1) and extending substantially beyond the perimeter that defines the bases of the prism, and in which the point of flexural fold or extreme flexural force of said at least one fin (6) is between 10 and 2000 kgf ( 100 N and 20 kN).
