Abstract

Perfeccionamiento en la protección contra el desgaste de una tobera de soplado para afino de los metales líquidosestando alimentada en el centro esta tobera sumergida con un gas oxidanteque puede ser oxígeno puroy estando alimentada en su periferia con un agente protector en estado líquidoteniendo este perfeccionamiento por finalidad simultáneareducir la velocidad de desgaste de la toberay reducir el consumo de líquido protector a la tobera escomo máximoigual a 2 milímetros cuadrados por centímetro de circunferencia de la citada toberacomo porque el caudal de líquido así introducido por centímetro de circunferencia en el lugar de la sección transversal de paso del líquido protector está comprendido entre 005 y 014 litros por minuto.
