Analysis Of The Characteristics Of The Blast Furnace Peripheral Zone.

Abstract: It is known that the minimum flow of coke rate is reached when CO use is at a maximum in the blast furnace. This is achieved when the peripheral zone carries the furnace's maximum permissible load and is operating with an open center. An overloaded in the circumference leads to an increase in the FeO content of the primary residue, which is not conducive for the creation of steady-state soot in the furnace waist and shoulders. This leads not only to an increase in heat loss, but also accelerates the wearing of the lining. The purpose of this research was to study the characteristics of heat emissions and recovery work in the peripheral zone of the blast furnace. Modern feeders allow you to distribute charge so as to achieve maximum degree of reduction potential of the gas stream. However, there were risks associated sustainability in the skull and shoulders thrust. Therefore the development of measures to ensure the operation of peripheral zone of the blast furnace, is an urgent task. The developed model to calculate the gas temperature and its recovery in the peripheral zone of the blast furnace can be used to optimize the thermal state of the shaft furnace in the peripheral zone.
