Abstract
It is expedient to modify blast furnace profiles so as to better suit new raw materials and fuel additives. Research shows that the shaft height may be increased and the cross section may be enlarged. It is clear from practical experience and the available data regarding the physical and chemical properties of batch components that the inclination of the shaft and the shoulders may be decreased when the batch consists entirely of pellets and pulverized coal injection is employed. With decrease in inclination of the shoulders to 76° at one blast furnace of Yenakiieve Iron and Steel Works, normal thermal conditions may be ensured in the section between the shoulders and the bottom of the shaft over a five-year run after startup.
