Abstract
Dispositivo para la introducción de medios de tratamiento cálcico en la fabricación de acero con características de tenacidad aumentadas, caracterizado porque para la introducción de medios de tratamiento cálcico finamente granulados en masas fundidas de acero, quede constituido por una batería del gas de sustentación, un depósito para el medio de tratamiento finamente granulado, un suspensador y una lanza de inmersión, dispuestos en el fondo del depósito con una tubuladura para la introducción del gas de sustentación y un salidero para la suspensión, la cual lanza a través de un conducto de transporte para la corriente de suspensión está en comunicación con el salidero del suspensador y se prevee que el conducto de transporte tiene una cámara de mezcla que permite una entrada de gas a presión en la corriente de suspensión, y porque la cámara de mezcla a través de un conducto secundario con una válvula de regulación está en comunicación con le cabeza del depósito, mientras la batería del gas de sustentación está acoplada a la tubuladura pera la introducción del gas de sustentación en el suspensador.
