LAS CROMITAS REFRACTARIAS DE CAMAGÜEY COMO FUENTE DE CROMO PARA ELECTRODOS REVESTIDOS PARA EL RECARGUE POR SOLDADURA

Abstract

El aprovechamiento de las cromitas refractarias disponibles en la provincia de Camagüey y las capacidades instaladas en la fábrica de electrodos de Nuevitas constituyen potencialidades para la fabricación de electrodos revestidos para el recargue por soldadura. El objetivo del trabajo consistió en evaluar las potencialidades de las cromitas refractarias del yacimiento Victoria I de Camagüey, como fuente de cromo para el desarrollo de electrodos para soldadura SMAW destinado al recargue de piezas. Se utilizaron como materias primas la mezcla de rutilo, el grafito, la cromita refractaria, silicato de sodio y varillas de acero AISI 1009. Los electrodos experimentales se obtuvieron mediante prensado del revestimiento a partir de una mezcla dosificada con los componentes anteriores. El balance de masa mostró que es posible alear con carbono y cromo el cordón de soldadura a partir de introducir en el revestimiento de rutilo cromita refractaria y grafito. Los resultados experimentales corroboraron que el proceso de soldadura permitió obtener 2,31 % de carbono y 2,89 % de cromo en el metal depositado por los electrodos experimentales. Los resultados obtenidos muestran que las cromitas refractarias de Camagüey constituyen una fuente barata de cromo para la fabricación de electrodos con revestimiento de rutilo para el recargue de piezas mediante soldadura SMAW.
