It is known that the cohezive zone in the blast furnace will be formed as a result of a softening of an iron ore component of burden, coke is in solid state. This zone makes limiting impact on productivity of the blast furnace [2]. Location and a form of a cohezive zone substantially is determined by character of unevenness of the temperature field depending on system of loading, the location of the tuyere center, a profile of shaft and change of gas dynamic resistance by height of the blast furnace; in temperatures of a softening and melting of the iron ore material, depending on extent of reduction [3]. Results of calculations of location and form of a zone of a cohezive in the blast furnace for iron ore materials with different metallurgical characteristics are given. References: [1] A.N. Dmitriev.
