Abstract
The article presents the study of connection between thermodynamics and kinetics of iron oxide reduction and production intensity. Model equations were developed for assessing the changes in degree of carbon monoxide use at the change in production intensity. Industrial data of blast furnace production with the useful volume of 2000 and 3200 confirmed the adequacy of the developed model. It was found that, the change in production intensity is accompanied by unsteady thermal state at high degree of developmental reproduction processes.
