Abstract
La presente invención se refiere a un conjunto de compuerta deslizante para emplearse con un recipiente de trabajo de metal que comprende por lo menos una placa refractaria estacionaria y por lo menos una placa refractaria deslizante, acoplada deslizablemente con la placa estacionaria, teniendo cada una de las placas refractarias por lo menos un pasaje a través de las mismas y separado en relación una de la otra de manera que la placa refractaria deslizante pueda moverse para poner su pasaje hacia y fuera de alineamiento con el pasaje de la por lo menos una placa estacionaria, a fin de efectuar la descarga o retención del metal fundido en el recipiente de trabajo de metal; consistiendo por lo menos una porción de cada una de las placas refractarias esencialmente de un refractario de magnesita ligada con carbón de elevada resistencia, no calcinada, que consiste de por lo menos aproximadamente 5 por ciento en peso de carbón y por lo menos aproximadamente 74 por ciento en peso de magnesita.
