Abstract

La tobera de soplado está compuesta por un cuerpo hueco de forma conica con una camisa interior y una camisa exterior así como también una parte frontalque une a las mismas, a través de cuya camisa interior se conduce el aire caliente que seintroduc e en el horno de cubilote y a través de cuyo espacio huecoformado entre la camisa interior y la camisa exterior se hace circular, durante el funcionamiento, una corriente de refrigeracion, estando dividido el espaciohueco en una antecámaraque se enc uentra en la parte frontal y una cámara principal adyacente, las cuales están separadas hidráulicamente entre sícompletamente, y presentan un circuito de medio refrigerante separado con conexiones propias, en donde el circuito de mediorefrigerante p ara la antecámaraestá formado por dos canales ubicados en forma paralela al eje longitudinal de la tobera de soplado, que forman la alimentacion y el retorno, y presentan unaseccion transversal casi constante, los cuales desembocan enla parte fronta l en un canal anular ubicado transversalmente con respecto a los canales y elcircuito del medio refrigerante de la cámara principal (10) está provisto de un canal de refrigeracion conformado de manera espiralada y presenta, visto alolargo, una sec cion casi constante, la camisa exterior (2) está formada por un cuerpo básico (1) de una sola pieza, de seccion transversal simétrica conrespecto al eje vertical, que pasa frontalmente sin discontinuidades a la parte frontal (5) yla camisa interior (3) está formada por una pieza soldada (4) deforma conica, y los canales (11, 13) que alimentan y descargan el medio refrigerante en la parte frontal (5), se encuentran ubicados en la posicion de las 12en punto de la tobera desoplado y, con respecto al eje longitudinal de la tobera de soplado, se encuentran fuera de la seccion transversal original de lacámara principal (10) de la tobera de soplado, y la pieza soldada (4) forma la cubierta interior del canal derefrigeracion (15) conformado en f orma espiraladade la cámara principal (10).The blow nozzle is composed of a conical hollow body with an inner jacket and an outer jacket as well as a front part that joins them, through whose inner jacket the hot air that is introduced into the furnace of cupola and through whose hollowed space between the inner jacket and the outer jacket a cooling stream is circulated during operation, the space being divided into an antechamber that is located in the front and an adjacent main chamber, which they are hydraulically separated from each other completely, and have a separate refrigerant medium circuit with their own connections, where the half-cooling circuit for the antechamber is formed by two channels located parallel to the longitudinal axis of the blow nozzle, which form the supply and the return, and present an almost constant transverse section, which lead to p Frontal art 1 in an annular channel located transversely with respect to the channels and circuit of the cooling medium of the main chamber (10) is provided with a spirally formed cooling channel and has, seen alolargo, an almost constant section, the outer jacket (2) is formed by a basic body (1) of a single piece, with a symmetrical cross section relative to the vertical axis, which passes frontally without discontinuities to the front part (5) and the inner jacket (3) is formed by a welded part (4) deforms conical, and the channels (11, 13) that feed and discharge the cooling medium in the front part (5), are located at the 12 o'clock position of the blown nozzle and, with respect to the longitudinal axis of the blow nozzle, are located outside the original cross section of the main chamber (10) of the blow nozzle, and the welded part (4) forms the inner cover of the cooling channel (15) c formed in a spiral fashion of the main chamber (10).
