Abstract

PROCEDIMIENTO DE ELABORACION DE ACEROS QUE PRESENTAN UNA ESTRUCTURA ISOTROPA Y UNA GRAN APTITUD PARA LA CONFORMACION EN FRIO. CONSISTE EN INTRODUCIR EN UN ACERO LIQUIDO DESOXIDADO Y CON BAJO CONTENIDO DE SILICIO UN ALAMBRE FORRADO QUE CONTIENE UN MATERIAL DIVIDIDO, QUE ES UNA MEZCLA DE SILICO-CALCIO Y DE CALCIO EN FORMA DE GRANOS EN CANTIDADES Y EN PROPORCIONES DETERMINADAS. ESTE PROCEDIMIENTO SE APLICA A ACEROS NO ALEADOS O ESCASAMENTE ALEADOS, Y ES PARTICULARMENTE CONVENIENTE EN EL CASO DE UNA INSTALACION DE COLADA CONTINUA.
