Abstract

Horno eléctrico para la producción de óxidos metálicos. El horno comprende una cámara tubular interna para el tratamiento de la materia prima, montada en el interior del cuerpo envolvente del horno aislado con respecto al exterior y dotado de sistemas de resistencia internas para el calentamiento de la cámara del horno por radiación, comprendiendo medios de alimentación de materia prima por un extremo y medios de control de salida de producto terminado por el otro extremo de la cámara de tratamiento del horno, en cuyo interior está montado con capacidad de giro un husillo sin fin accionado exteriormente en giro, quedando incorporados en los extremos terminales del husillo sendos dispositivos percutores para evitar el apelmazado de la masa sobre el husillo.
