ABSTRACT:
A process for operating blast furnaces is disclosed, which comprises assuming a plurality of reference spaces, each of which serves as a stacking space for burden material and is defined by a plurality of line segments having inclination angles .theta..sub.1 and .theta..sub.2 with respect to a horizontal line on a surface of a previously stacked burden, before a predetermined volume of the burden material is charged from a charging equipment; settling a newly stacked surface of the burden in one of the standard spaces in such a manner that the newly stacked surface consists of two line segments having inclination angle .theta..sub.1 and .theta..sub.2 with respect to the horizontal line and intersecting with a falling trajectory of the burden so that a space defined between the newly stacked surface and the previously stacked surface corresponds to the predetermined volume of the burden material; and then charging the predetermined volume of the burden material from the charging equipment up to the position of the newly stacked surface on the previously stacked surface.
