Abstract

L'invention concerne un procédé de réduction partielle de matières à base d'oxydes de fer par un plasma dans lequel on introduit du combustible carboné et un gaz contenant de l'oxygène. La direction des jets de plasma est choisie de manière à ce que les axes longitudinaux des jets de plasma forment un angle central avec un sommet sur l'axe du réacteur et que le sommet de l'angle soit disposé plus haut que la hauteur prédéterminée du miroir du métal. Les jets sont introduits à une hauteur égale à 0,5 - 0,8 H de la sole du four de fusion, H étant la hauteur globale de chargement de la matière. Le métal réduit est évacué en permanence de la zone de fusion dans un avant-creuset; de plus, il est purgé par un jet de plasma neutre / d'oxydation, neutre / de réduction ou un jet neutre, et le gaz contenant de l'oxygène est injecté dans le plasma sous la forme d'un mélange air / eau. L'installation comprend un réacteur, dont le corps (1) est revêtu de l'intérieur d'un matériau réfractaire (2). Dans la partie inférieure du réacteur on a ménagé une zone de fusion / de réduction (3) munie de moyens d'amenée de milieu de transport d'énergie et de réducteur via des plasmotrons (4). Dans la partie supérieure du réacteur on a ménagé un moyen (9) de réduction partielle et un moyen (14) de chargement. Les plasmotrons (4) sont montés opposés sur le périmètre du réacteur, sous un angle de 30 à 50° par rapport à l'horizon, en direction de la sole du four, de manière à ce que les axes longitudinaux des plasmotrons disposés de manière symétrique se croisent sur l'axe du réacteur, avec le sommet de l'angle situé plus haut que la hauteur prédéterminée du miroir du métal. L'avant-creuset (21) est ménagé dans la partie inférieure du réacteur et comprend un orifice de sortie (7) ainsi qu'un plasmotron supplémentaire de soufflage et de raffinage (24).
