Description

Technical Field

[0001] This application relates to the technical field of blast furnace production, and particularly relates to a method, system, electronic device and storage medium for determining the temperature of the thermal reserve zone. Background Art

[0002] The thermal reserve zone of a blast furnace is an area where the heat exchange between the gas and the burden in the furnace body is very slow. Generally speaking, the bottom temperature of the thermal reserve zone is determined by the coke dissolution process and should not be lower than the starting temperature of the coke dissolution reaction in the blast furnace. Under the action of the temperature in the thermal reserve zone of the blast furnace, both magnetite and iron oxide in the iron-bearing burden will undergo reduction reactions, generating iron oxide and iron respectively. In the actual generation process, the reaction of iron oxide being reduced to iron is the main one.

[0003] The temperature of the burden in the thermal reserve zone of the blast furnace is not much different from the gas temperature. Research shows that the temperature difference between the two is about 10 - 30°C. The temperature of the thermal reserve zone is an important parameter in blast furnace ironmaking production. The temperature of the thermal reserve zone is affected by factors such as the direct reduction degree, gas volume, and burden water equivalent. The level of the temperature in the thermal reserve zone has a direct and important impact on the blast furnace temperature distribution and indirect reduction, and further affects the heat utilization and carbon consumption of the blast furnace. If the temperature in the thermal reserve zone is too high, although the thermodynamic and kinetic conditions for indirect reduction are relatively good, it will come at the cost of consuming more carbon, resulting in too high a temperature of the top gas and low heat utilization efficiency. If the temperature in the thermal reserve zone is too low, the kinetic conditions for indirect reduction are poor, the direct reduction degree increases, and the heat consumption in the lower part of the furnace body is too large, leading to disordered temperature distribution in the furnace and causing unstable furnace conditions. An appropriate temperature in the thermal reserve zone can not only achieve good indirect reduction, fully improve the gas utilization rate, but also effectively utilize heat energy, ensure stable furnace conditions, and reduce carbon consumption.
