Abstract

UNA CAMPANA INFERIOR PARA EL PROCEDIMIENTO CAS-OB (COMPOSITION ADJUSTMENT BY SEALED ARGON BUBBLING-OXYGEN BLOWING) EN ACERIAS, MUESTRA UNA BRIDA ALINEADA EN HORIZONTAL QUE SIRVE PARA ALOJAR LA CAMPANA SUPERIOR Y UNA PIEZA DE REFUERZO FIJADA METALICAMENTE EN LA BRIDA. LA PIEZA DE REFUERZO PUEDE ESTAR FORMADA POR UNAS BARRAS DE ACERO (12) ALINEADAS VERTICALMENTE, QUE SE ENCUENTRAN DISTRIBUIDAS POR EL PERIMETRO DE LA BRIDA (10) Y CUBIERTAS POR UN MATERIAL REFRACTARIO (11), O ESTAR COMPUESTA POR UNA ENVOLTURA DE CHAPA CONTINUA, QUE SE ENCUENTRA HENDIDA POR UNA GRAN CANTIDAD DE RANURAS E IGUALMENTE RODEADA POR UN MATERIAL REFRACTARIO.A BOTTOM HOOD FOR THE CAS-OB PROCEDURE (COMPOSITION ADJUSTMENT BY SEALED ARGON BUBBLING-OXYGEN BLOWING) IN ACERIAS, SHOWS A HORIZONTAL Flanged FLANGE THAT SERVES TO STAY THE TOP HOOD AND A METAL REINFORCED PIECE. THE REINFORCEMENT PIECE MAY BE FORMED BY VERTICALLY ALIGNED STEEL BARS (12), WHICH ARE DISTRIBUTED BY THE PERIMETER OF THE FLANGE (10) AND COVERED BY A REFRACTORY MATERIAL (11), OR BE COMPOSED BY A WRAP , WHICH IS CLEARED BY A GREAT AMOUNT OF SLOTS AND EQUALLY SURROUNDED BY A REFRACTORY MATERIAL.
