An operation management method of a production process for obtaining an iron carbide having a target composition in two stages of reaction procedures, comprising conducting a second reaction operation for executing remaining reduction and carburization operations after a first reaction operation for partly reducing an iron-containing raw material for producing iron, collecting a solidified sample at an outlet of a reaction furnace after the first reaction operation, measuring a reaction rate of the solidified sample, and controlling an IC rate after the second reaction operation by controlling parameters capable of changing the reduction rate of the first reaction operation.

L'invention a trait à une technique de production de carbure de fer d'une composition souhaitée et ce, en deux phases réactionnelles. On provoque, au titre de ce procédé, après une première réaction visant à réduire partiellement une matière première contenant du fer afin de produire du fer, une seconde réaction aux fins d'une réduction et d'une cémentation au carbone résiduelles. On recueille à la sortie d'un four de réaction, après la première réaction, un échantillon solidifié dont on mesure la vitesse de réaction et l'on agit, après la seconde réaction, sur la teneur en carbure de fer en commandant à des paramètres capables de modifier la vitesse de réduction de la première réaction.
