抄録

The results of experimental investigations of reduction of magnetite pellets with different granulations of added charred coal, under nitrogen atmosphere, in the temperature range of 1273 to 1384 K, are given in this paper. The kinetic parameters, activation energy and preexponential factor have been determined, which enabled defining of the rate constant and charred coal granulation's dependencies upon temperature and dependence of the reduction course upon time, temperature and charred coal granulation.<BR>Also, the dependence of reduction activation energy on specific surface area and average grain diameter of added solid reducer-charred coal are presented.
