Abstract

Un material refractario para revestimiento del sistema de distribucion de un acero fundido cuando el acero se moldea por el procedimiento de vertido por abajo, y se presentan y describen cuerpos perfilados producidos a partir de dicho material refractario. Con el fin de evitar de manera fiable inclusiones no metálicas en el acero producido por el procedimiento de vertido por abajo, y para incrementar la calidad del acero, se propone que el material refractario contenga componentes que contengan carbono al menos en el lado de acero, se adhiera a, y/o se recubra con y/o se impregne de estos componentes. Los cuerpos perfilados producidos a partir de dicho material pueden obtenerse por medio de pultrusion como material ahuecado o bien adherirse con carbono por presion en seco.
