Abstract
EL PROCEDIMIENTO SEGUN EL INVENTO SE CARACTERIZA PROQUE SE REALIZA UNA REFRIGERACION ENERGICA DEL PRODUCTO EN CURSO DE COLADA CONTINUA CUANDO ESTE SE ENCUENTRA CON EL NUCLEO EN FASE DE SOLIDIFICACION PASTOSA (8), DE MANERA QUE LA CONTRACCION TERMICA DIFERENCIAL ENTRE EL NUCLEO PASTOSO Y LA CORTEZA EXTERIOR YA COMPLETAMENTE SOLIDIFICADA, PRODUCE UN EFECTO DE OPRESION DEL NUCLEO POR LA CORTEZA (9). PARA ESTO, SE DISPONEN UNOS MEDIOS DE REFRIGERACION DEL PRODUCTO EN LA MAQUINA DE COLADA A NIVEL DE LA PORCION TERMINAL DE LA LONGITUD METALURGICA. EL INVENTO PERMITE REDUCIR HASTA EVITAR LA FORMACION DE FISURAS INTERNAS EN EL CURSO DE REFRIGERACION DEL PRODUCTO COLADO, QUE CONDUCIRIAN A LA PRESENCIA DE PLAYAS SEGREGADAS EN LA ZONA AXIAL. SE APLICA VENTAJOSAMENTE EN LA COLADA DE ACEROS REPUTADOS DIFICILES DE COLAR EN CONTINUO, COMO LOS ACEROS CON LARGO INTERVALO DE SOLIDIFICACION CUYO CONTENIDO EN CARBONO ES DE UN 0,25 A 1,5%.
