Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO PARA LA FABRICACION DE UNA ELECTROCHAPA CON GRANOS ORIENTADOS, MEDIANTE EL CUAL UN LLANTON DE ACERO SE CALIENTA A UNA TEMPERATURA INFERIOR A LA TEMPERATURA DE SOLUBILIDAD DEL SULFURO DE MANGANESO, PERO SUPERIOR A LA TEMPERATURA DE SOLUBILIDAD DEL SULFURO DE COBRE. A CONTINUACION EL LLANTON SE ENROLLA EN CALIENTE CON UNA TEMPERATURA INICIAL DE AL MENOS 960 °C Y UNA TEMPERATURA FINAL DE 880 HASTA 1000 °C HASTA CONSEGUIR UN GROSOR FINAL DE LA BANDA DE 1,5 HASTA 7,0 MM. LA BANDA CALIENTE SE RECUECE DESPUES DURANTE 100 A 600 S A UNA TEMPERATURA DE 880 HASTA 1150 °C, Y DESPUES SE ENFRIA CON UNA TASA DE ENFRIAMIENTO MAYOR DE 15 K/S. EN UNA O VARIAS ETAPAS DE ENFRIAMIENTO LA BANDA SE ENFRIA. FINALMENTE SE TERMINA CON UN RECOCIDO DE RECRISTALIZACION CON DECARBURACION SIMULTANEA, LA APLICACION DE UN AGENTE DE SEPARACION, UN RECOCIDO A ELEVADA TEMPERATURA, Y DESPUES DE LA APLICACION DE UNA CAPA AISLANTE EL RECOCIDO FINAL. ES CARACTERISTICO DE LA INVENCION QUE LABANDA FRIA SE CALIENTE HASTA UNA ELEVADA TEMPERATURA DE RECOCIDO EN UNA ATMOSFERA QUE CONTIENE MENOS DEL 25 % EN VOLUMEN DE H 2 , Y EL RESTO ES NITROGENO Y/O GAS NOBLE AL MENOS HASTA LLEGAR A LA TEMPERATURA CRITICA.
