Abstract

EN DONDE EL ELEMENTO REFRIGERANTE COMPRENDE UNA SECCION DE MARCO DE COBRE Y UNA RED DE CANALES HECHA EN LA SECCION DEL MARCO PARA LA CIRCULACION DEL MEDIO REFRIGERANTE. EL METODO COMPRENDE FORMAR MEDIANTE RECUBRIMIENTO CON ASPERSION TERMICA, UN REVESTIMIENTO RESISTENTE A LA CORROSION SOBRE POR LO MENOS PARTE DE LA SUPERFICIE DEL ELEMENTO, YA SEA EN LA ETAPA DE PRODUCCION O EN EL SITIO MISMO DEL ELEMENTO EN EL HORNO. EL REVESTIMIENTO PUEDE SER METAL PURO, CARBURO, OXIDO, ALEACION ESPECIAL Y/O TODOS O ALGUNOS DE LOS ELEMENTOS MENCIONADOS, PARTICULARMENTE NIQUEL, MOLIBDENO, CROMO, SILICONA, HIERRO O COBALTO. UNA CAPA DE TRANSMISION, QUE COMPRENDE ESTANO O UNA ALEACION QUE LO CONTIENE, SE FORMA ENTRE EL REVESTIMIENTO Y LAS SUPERFICIES DE EMPALME DEL ELEMENTO ANTES DE LA FORMACION DEL EMPALME. LA TECNOLOGIA DE ASPERSION SE BASA EN COMBUSTION DE GAS, ASPERSION DE OXIGENO-COMBUSTIBLE A ALTA VELOCIDAD, O ASPERSION POR FLAMA. EL MATERIAL DE REVESTIMIENTO DEL ELEMENTO ESTA EN FORMA PULVERIZADA O DE ALAMBREWHERE THE REFRIGERANT ELEMENT INCLUDES A COPPER FRAME SECTION AND A NETWORK OF CHANNELS MADE IN THE FRAME SECTION FOR THE CIRCULATION OF THE COOLING MEDIUM. THE METHOD INCLUDES FORMING BY COATING WITH THERMAL SPRAY, A COATING RESISTANT TO CORROSION ON AT LEAST PART OF THE SURFACE OF THE ELEMENT, EITHER IN THE PRODUCTION STAGE OR IN THE SITE OF THE ELEMENT IN THE OVEN. THE COATING MAY BE PURE METAL, CARBIDE, OXIDE, SPECIAL ALLOY AND / OR ALL OR SOME OF THE MENTIONED ELEMENTS, PARTICULARLY NICKEL, MOLYBDENUM, CHROME, SILICONE, IRON OR COBALT. A TRANSMISSION LAYER, INCLUDING TANE OR AN ALLOY CONTAINING IT, IS FORMED BETWEEN THE COATING AND THE ELEMENT'S JOINT SURFACES BEFORE THE JOINT FORMATION. SPRAY TECHNOLOGY IS BASED ON GAS COMBUSTION, OXYGEN-FUEL SPRAY AT HIGH SPEED, OR FLAME SPRAY. ELEMENT COATING MATERIAL IS IN SPRAY OR WIRE FORM
