Abstract
PROCEDIMIENTO DE ELIMINACION DE ESCORIA DEL FONDO DE HORNOS EMPLEADOS EN LA INDUSTRIA SIDERURGICA. CONSISTENTE EN SUMINSTRAR A LA ESCORIA UNA SUSTANCIA CAPAZ DE REBAJAR SU PUNTO DE FUSION, TAL COMO EL FERROSILICIO, JUNTO CON OTRA SUSTANCIA WQUE INICIE LA FUSION DE DICHA ESCORIA POR MEDIO DE UNA REACCION QUIMICA EXOTERMICA, FUSION QUE LUEGO CONTINUA MEDIANTE LA APLICACION DE CALOR A LA MISMA, DE FORMA QUE SE ALCANCE LA FLUIDEZ ADECUADA QUE PERMITA SU ELIMINACION MEDIANTE UNA CUCHARA MECANICA; TAL FLUIDEZ SE CONTROLA MEDIANTE LA ADICION, EN LOS MOMENTOS OPORTUNOS, DE SUSTANCIAS ESPESANTES, TALES COMO EL ESPATOFLUOR. LA SUSTANCIA EMPLEADA PARA LLEVAR A CABO LA REACCION EXOTERMICA CONTIENE AL Y FE2O3 FINALMENTE DIVIDIDOS. SE PALICA A HORNOS DE RESUDADO O TERMODIFUSION DE LAMINADORES DE PALASTRO EN BRUTO QUE TRABAJAN A UNOS 1.300 C.
