FERREIRO GUERRERO, Yosvany; SANCHEZ CRUZ, Alexeis; PALACIOS RODRIGUEZ, Amaury  e  GARCIA HIDALGO, Evangelina. Carbothermic Reduction of Iron Concentrate from Solid Residuals of Nicaro to Obtain Pig-iron Nuggets. RTQ [online]. 2016, vol.36, n.1, pp. 67-78. ISSN 2224-6185.

The results of the application of the process of reduction by coal to the solid residuals of the company  “Rene Ramos Latour”, belonging to the town of Nicaro in Cuba, for the obtaining of pig-iron nuggets, being the processes that use  rotary heart furnace  the most feasible from the economic and environmental technical point of view. The complete factorial experimental design is planned, introducing as independent variables the temperature, the basicity, the content of coal and the diameter of the pellet, to analyze its influences in the grade of reduction of the iron.  It is demonstrated that it is possible to obtain for the first time in Cuba pig-iron nuggets starting from the residual one studied, with the presence of alloy elements such as: chrome, silicon, nickel, manganese, cobalt, vanadium, among other, which can be employees as matter prevail for the production of stainless steels as well as steels of low alloy to the chromium and nickel.

Palavras-chave : industrial solid residuals; reduction by coal; pig iron nuggets.
