Abstract

LA CALIDAD INTERNA DE LAS PIEZAS FUNDIDAS CONTINUAMENTE Y DE OTRAS MUESTRAS DE ACERO A MODO DE LINGOTES, TOCHOS, LUPIAS, LAMINAS Y BARRAS SE DETERMINA DE MANERA RAPIDA PARA PERMITIR IDENTIFICAR Y CORREGIR CON TIEMPO LAS CONDICIONES DE FUNDICION QUE POTENCIALMENTE PUEDEN CAUSAR PROBLEMAS. SE DECAPA ANODICAMENTE UNA MUESTRA DE ACERO DE LA PIEZA DE FUNDICION, DESPUES DE PULIRLA PARA ELIMINAR CUALQUIER ZONA AFECTADA POR EL CALOR Y DE OBTENER EL GRADO DE RUGOSIDAD SUPERFICIAL DESEADO, UTILIZANDO UN ACIDO HIDROCLORICO DILUIDO A TEMPERATURA AMBIENTE PARA DECAPAR EL METAL DE LA SUPERFICIE Y PODER VER LA CALIDAD INTERNA. TRAS LA RETIRADA DE LA MUESTRA DEL APARATO DE DECAPADO, SE LAVA, SE SECA Y SE EXAMINA VISUALMENTE LA MUESTRA PARA DETERMINAR LA CALIDAD INTERNA.
