Abstract
PROCEDIMIENTO E INSTALACION PARA LA FABRICACION DE BRIQUETAS DE MATERIA PRIMA PARA LA PRODUCCION DE SILICIO, CARBURO DE SILICIO O FERROSILICIO. PROCEDIMIENTO PARA LA FABRICACION DE BRIQUETAS DE MATERIA PRIMA PARA LA PRODUCCION DE SILICIO, CARBURO DE SILICIO O FERROSILICIO EN UN HORNO ELECTRICO DE CUBA BAJA, EN EL QUE SE MEZCLAN ARENA CUARZOSA, UN PORTADOR DE CARBONO Y UN AGLOMERANTE BITUMINOSO Y LA MEZCLA SE CONFIGURA COMO PREFORMAS, Y EN EL QUE A PARTIR DE LAS PREFORMAS SON FORMADAS LAS BRIQUETAS DE MATERIA PRIMA MEDIANTE UN TRATAMIENTO TERMICO. SE TRABAJA CON PREFORMAS LIBRES DE CARBON AGLUTINANTE FUNDIDO, CUYO PESO ESPECIFICO, MEDIANTE AJUSTE DE LA RELACION DE MEZCLA Y DE LA CONSOLIDACION Y DENSIFICACION, ES MAYOR QUE LA DENSIDAD APARENTE DE LA ARENA CUARZOSA. ESTAS PREFORMAS, CON EL FIN DE REALIZAR EL TRATAMIENTO TERMICO, SE INTRODUCEN EN UN HORNO TUBULAR ROTATORIO CALENTADO, QUE ESTA LLENO EN SU PARTE INFERIOR CON ARENA CUARZOSA EN UN GRADO TAL QUE EL TRATAMIENTO TERMICO SE EFECTUA DENTRO DE UN LECHO DE INMERSION DE ARENA CUARZOSA.
