Abstract
SE DESCRIBE UN METODO PARA LA REPARACION DE UNA PORCION DEFECTUOSA DE UN REVESTIMIENTO REFRACTARIO DE UNA PARED DE UN HORNO DE CUBA, EJ. UN ALTO HORNO. EL REVESTIMIENTO TIENE UNOS PANELES REFRIGERADOS CON AGUA (5) COLOCADOS EN EL INTERIOR DE LA CHAQUETA DE ACERO DEL HORNO (3) Y AL MENOS UNA CAPA INTERIOR (6) DE UN MATERIAL DE REVESTIMIENTO REFRACTARIO EN EL INTERIOR DE LOS PANELES (5). EL METODO CONSISTE EN LOS PASOS DE RETIRAR AL MENOS UNO DE LOS PANELES REFRIGERADOS CON AGUA (5) DEL LUGAR EN QUE SE ENCUENTRA LA PORCION DE REVESTIMIENTO DEFECTUOSA, SUSTITUIR EL PANEL O PANELES RETIRADOS POR UNA CAPA DE REVESTIMIENTO REFRACTARIO ADICIONAL (11) QUE TENGA UNA CONDUCTIVIDAD TERMICA ELEVADA, EJ. AL MENOS 50 W/MK, Y PROPORCIONARLE A LA CHAQUETA DE ACERO DEL HORNO (3) DE LA REGION DE REPARACION, UN SISTEMA DE REFRIGERACION POR AGUA (12,13,14).A METHOD FOR THE REPAIR OF A DEFECTIVE PORTION OF A REFRACTORY COATING OF A WALL OF A CUBA OVEN, EJ. IS DESCRIBED. A HIGH OVEN. THE LINING HAS SOME WATER-COOLED PANELS (5) PLACED INSIDE THE OVEN'S STEEL JACKET (3) AND AT LEAST ONE INSIDE LAYER (6) OF A REFRACTORY LINING MATERIAL INSIDE THE PANELS (5). THE METHOD CONSISTS OF THE STEPS OF REMOVING AT LEAST ONE OF THE PANELS REFRIGERATED WITH WATER (5) FROM THE PLACE IN WHICH THE PORTION OF DEFECTIVE LINING IS FOUND, REPLACING THE PANEL OR PANELS REMOVED BY AN ADDITIONAL REFRACTORY LAYER (11) A HIGH THERMAL CONDUCTIVITY, EX. AT LEAST 50 W / MK, AND PROVIDE TO THE OVEN STEEL JACKET (3) FROM THE REPAIR REGION, A WATER COOLING SYSTEM (12,13,14).
