Abstract

Procedimiento de reciclado de polvo de acería y producto obtenido con este procedimiento, en el que a un polvo de acería de composición: óxidos de hierro 20 {- 50%; óxido de zinc 10 {- 45 %, en partículas de tamaño inferior a 150 {u , se le mezcla en una mezcladora de homogeneización con un compuesto reductor de base carbono de 12 {- 20 % en peso en partículas de tamaño inferior a 200 {u y con un aglomerante orgánico de 1,5 {- 4 % en peso, para una vez homogeneizada la mezcla es sometida a un prensado hasta obtener una densidad de entre 2 y 3,3 gr./cm{sup,3 y luego se somete a su curado. Aplicable en la metalurgia del acero.Recycling process of steel powder and product obtained with this procedure, in which to a steel powder of composition: iron oxides 20 {- 50%; 10 {-45% zinc oxide, in particles smaller than 150 {u, is mixed in a homogenization mixer with a carbon-based reducing compound of 12 {-20% by weight in particles smaller than 200 { o and with an organic binder of 1.5 {-4% by weight, for once the mixture is homogenized it is subjected to a pressing until a density of between 2 and 3.3 gr./cm{sup.3 is obtained and then subjected to his cure. Applicable in steel metallurgy.
