| Abstract Scope |
Carbothermal reduction experiments were carried out using previously characterized mixtures of two types of coal: mineral coke and charcoal. These were mixed one by one with steel scale from the heat treatment of Peruvian manganese steel castings. The experiences used a design of experiments that involved factors such as: X1 (CS/MC) between 1⁄4 and 3⁄7, as well as, X1´:CS/Ch of 1⁄3 and 1⁄1 between 1⁄4 and 3 ⁄7, X2: temperatures of 800 °C and 1100 °C and X3 times of 20 and 60 min, and as a dependent variable Y: % Reduction. X1 in both processes X1 and X1' turned out to be the most influential individual factors in Y. The values of the estimated apparent activation energy ranged between 38 and 43 kJ/mol for the first case and between 25 and 29 kJ/mol for the second case using a spherically symmetric interface chemical reaction model. |
