Abstract

SE DESCRIBE UN APARATO CALEFACTOR (10) PARA CALENTAR UN RODILLO DE CALANDRA (12). EL APARATO CALEFACTOR (10) UTILIZA CALOR PROPORCIONADO POR INDUCCION CALORIFICA Y A TRAVES DE UN MEDIO TRANSMISOR DE CALOR. EL CALEFACTOR (10) INCLUYE CANALES DE CALENTAMIENTO DEFINIDOS EN EL RODILLO (12). LOS CANALES SE EXTIENDEN A TRAVES DEL RODILLO (12) DE FORMA QUE SE PERMITA FLUIR EL MEDIO DE TRANSMISION DE CALOR A TRAVES DE LOS CANALES, DE MANERA QUE EL CALOR SE TRANSFIERA DEL MEDIO DE TRANSMISION AL RODILLO (12). UN CALENTADOR DE INDUCCION (14) ESTA SITUADO ADYACENTEMENTE A LA SUPERFICIE EXTERNA (24) DEL RODILLO (12) Y SE EXTIENDE SUSTANCIALMENTE A LA LONGITUD TOTAL DEL RODILLO (12) DE FORMA QUE CUANDO SE ACTIVA EL CALENTADOR DE INDUCCION (14) EL CALOR SE INDUCE EN LA REGION DE LA SUPERFICIE EXTERNA (24) DEL RODILLO (12) PARA SUPLEMENTAR LA CANTIDAD DE CALOR TRANSFERIDA DESDE EL MEDIO DE TRANSMISION DE CALOR, DE MANERA QUE LA TEMPERATURA DE LA SUPERFICIE EXTERNA (24) DEL RODILLO (12) SE INCREMENTEA UN NIVEL QUE EN AUSENCIA DE CALENTAMIENTO POR INDUCCION (14) PRODUCIRIA UNA TENSION EXCESIVA EN LA PARED DEL RODILLO. ADEMAS, EL NIVEL DE TEMPERATURA ES ALCANZABLE SIN EL RIESGO ASOCIADO AL USO DEL MEDIO DE TRANSMISION DE CALOR OPERANDO AL MENOS A UN NIVEL DE TEMPERATURA SIMILAR.A HEATING APPLIANCE (10) IS DESCRIBED FOR HEATING A CALANDRA ROLL (12). THE HEATING APPLIANCE (10) USES HEAT PROVIDED BY HEAT INDUCTION AND THROUGH A HEAT TRANSMITTER. THE HEATER (10) INCLUDES DEFINED HEATING CHANNELS ON THE ROLLER (12). THE CHANNELS ARE EXTENDED THROUGH THE ROLLER (12) SO THAT THE HEAT TRANSMISSION MEDIA IS ALLOWED TO FLOW THROUGH THE CHANNELS, SO THAT THE HEAT IS TRANSFERRED FROM THE TRANSMISSION MEDIA TO THE ROLLER (12). AN INDUCTION HEATER (14) IS LOCATED ADJACENTLY TO THE EXTERNAL SURFACE (24) OF THE ROLLER (12) AND EXTENDS SUBSTANTIALLY TO THE TOTAL LENGTH OF THE ROLLER (12) SO WHEN THE INDUCTION HEATER IS ACTIVATED (14) IT IS INDUCED IN THE REGION OF THE EXTERNAL SURFACE (24) OF THE ROLLER (12) TO SUPPLEMENT THE AMOUNT OF HEAT TRANSFERRED FROM THE HEAT TRANSMISSION MEDIA, SO THAT THE TEMPERATURE OF THE EXTERNAL SURFACE (24) OF THE ROLLER (12) IS INCREASES A LEVEL WHICH IN THE ABSENCE OF INDUCTION HEATING (14) WOULD PRODUCE EXCESSIVE TENSION IN THE WALL OF THE ROLLER. FURTHER, THE TEMPERATURE LEVEL IS REACHABLE WITHOUT THE RISK ASSOCIATED WITH THE USE OF THE HEAT TRANSMISSION MEDIA BY OPERATING AT LEAST AT A SIMILAR TEMPERATURE LEVEL.
