Abstract

Se proporciona una valvula corrediza para colada con un conjunto reemplazable de placas refractarias de valvula para facilitar las operaciones de mantenimiento. La valvula corrediza para colada generalmente comprende un armazon de metal montado en un recipiente metalurgico, por lo menos una placa refractaria fija con una abertura de flujo, por lo menos una placa refractaria movil con una abertura de flujo, una buza de colada firmemente conectada a la placa movil, un cilindro neumatico para controlar el desplazamiento de la placa movil con respecto a la placa fija para controlar el traslapo de las aberturas de flujo de las dos placas, y una estructura de interconexion para unificar las placas refractarias fija y movil y la buza de colada en un conjunto de placas de valvula que puede instalarse en y retirarse en una sola operacion del armazon de metal de la valvula corrediza para colada. Las placas refractarias pueden estar cubiertas de cascos de metal y la estructura de interconexion puede consistir de rieles deslizantes que se encajan y de huecos entre los dos cascos de metal que unifiquen a las placas refractarias durante la operacion de reemplazo, pero que permiten que el cilindro neumatico desplace a las placas fija y movil durante el funcionamiento de las valvulas corredizas para colada.
