Abstract

METODO PARA PRODUCIR COQUE ACICULAR CONSISTENTE EN: A) CALENTAR COQUE ACICULAR VERDE A TEMPERATURAS COMPRENDIDAS ENTRE 468JC Y 649JC, DURANTE UN TIEMPO ENTRE 10 MINUTOS Y 24 HORAS, APROXIMADAMENTE, EN UNA ESTUFA DEL TIPO DE PLANO INCLINADO; Y B) CALCINAR EL COQUE OBTENIDO A TEMPERATURAS SUPERIORES A 1.093º. ENTRE LAS ETAPAS A) Y B) LA TEMPERATURA DEL COQUE NO DEBE ENFRIARSE A MAS DE 260JC. COMO PASO PREVIO A LA ETAPA A), PUEDE SECARSE EL COQUE ACICULAR VERDE HASTA UN CONTENIDO EN AGUA INFERIOR AL 5% EN PESO. SE CONSIGUE DISMINUIR NOTABLEMENTE LA FRIABILIDAD DEL COQUE ACICULAR VERDE DESDE VALORES MAYORES DE 120 DEL INDICE DE MOLINACION HARDGROVE HASTA VALORES MENORES DE 70 DEL MISMO INDICE TRAS EFECTUAR LA ETAPA A). IGUALMENTE DISMINUYE LA CANTIDAD DE POLVOS PRODUCIDOS DURANTE LA CALCINACION. DE APLICACION COMO MATERIA PRIMA EN LA FABRICACION DE LOS ELECTRODOS DE GRAFITO QUE SE EMPLEAN EN LA INDUSTRIA DEL ACERO.
