Abstract
PROCEDIMIENTO DE TRATAMIENTO DE ACEROS. CONSISTE EN AÑADIR A ACEROS DESOXIDADOS CON MANGANESO, SILICIO Y ALUMINIO, FUNDIDOS, ELEMENTOS TALES COMO CALCIO, BORO MEDIANTE UN GAS PORTADOR INERTE. LOS CHORROS DE COLADA ENTRE LA CUCHARA Y LA ARTESA INTERMEDIA Y ENTRE LA ARTESA INTERMEDIA Y LA LINGOTERA SE PROTEGEN DEL CONTACTO CON AIRE. COMO ELEMENTO FORMADOR DE NITRUROS, SE INTRODUCE CIRCONIO Y/O TITANIO O ALEACIONES DE LOS MISMOS, INTRODUCIENDOLOS MEDIANTE UNA LANZA.
