Improving the durability of the masonry of a blast-furnace, along with increase in its output and reduction in coke consumption, is an important task of blast-furnace control. The most important factor of accomplishing these tasks is control of the temperature of the materials at the upper boundary of the tuyere zone and the belly and bosh adjacent to the furnace masonry at the bottom of the stack. A one-dimensional mathematical model run in real time as part of the automated process control system of the MMK BFs is used to solve the problems of gas dynamic and heat-and mass transfer processes between the stockline and the iron taphole (Domna model), and a two-dimensional mathematical model is used to additionally describe all the processes, including melting, in the vertical section of the furnace (Kogeziya model).

“…As a rule, mathematical models of the blast furnace process are used. In particular, [9][10][11] present the results of studies of the melting zone (cohesion) in the blast furnaces of Magnitogorsk Iron & Steel Works using a two-dimensional mathematical model of the blast furnace. But the authors typically refer to works published in the 1980s in collections of articles [12].…”

The paper considers the theoretical foundations of softening of iron ore materials in a blast furnace (the so-called ‘cohesion zone’). The dependences of the temperature range of softening of iron ore materials (the temperatures of the beginning and ending of softening) on the degree of reduction are calculated and experimentally obtained. Physical modelling of the softening process of reduced iron ore materials was carried out using the Russian State Standard No 26517-85. The results of calculations of the location and shape of the cohesion zone in the blast furnace for iron ore materials with different metallurgical characteristics are presented.
