Briquette iron obtained by the hot-molding of reduced-iron particles, the reduced-iron particles being adherent to one another. The reduced-iron particles each has a surface region which has an average carbon content of 0.1-2.5 mass% and a central region which is located inside the surface region and has a higher average carbon content than the surface region.
L'invention concerne une briquette de fer obtenue par moulage à chaud de particules de fer réduit, lesdites particules de fer réduit étant adhérentes les unes aux autres. Les particules de fer réduit ont chacune une région de surface ayant une teneur moyenne en carbone de 0,1 à 2,5 % en masse et une région centrale située à l'intérieur de la région de surface et ayant une teneur moyenne en carbone plus élevée que la région de surface.
