Abstract

Un inhibidor de vórtice para separar escoria de metal fundido durante la descarga de metal fundido a través de una buza de colada incluye un cuerpo refractario moldeable uniforme con una forma generalmente ahusada, una cámara hueca adentro del cuerpo y un miembro de sacrificio alargado. La cámara hueca recibe al miembro de sacrificio o un montaje para el miembro de sacrifico. La combinación de cuerpo refractario y miembro de sacrificio en metal fundido tiene una gravedad específica menor que la gravedad específica del metal fundida y se posiciona con el extremo angosto hacia abajo cuando está soportada en metal fundido. La cámara hueca puede llenarse con metal fundido para formar un núcleo que ayuda a orientar el cuerpo de una posición hacia abajo de extremo angosto. El miembro de sacrificio se alinea con el área en la cual se forma el vórtice y minimiza la interferencia con el flujo a través de la buza de colada. Preferiblemente el cuerpo incluye superficies que obstruyen el torbellino.
