Description

technical field [0001] The application relates to the field of iron and steel metallurgy, in particular to a furnace replacement method, furnace replacement device and control equipment for multiple blast furnace hot blast stoves. Background technique [0002] Blast furnace gas is obtained through gasification of coke in blast furnace production, and provides the main energy consumption resource for heating equipment in the upstream and downstream workshops of steel mills through pipelines. However, due to frequent fluctuations in gas consumption, the unbalanced gas consumption of the gas pipeline network and large fluctuations in the main pipe pressure have increased the difficulty of production operations and gas scheduling. In the blast furnace production process, the hot blast stove is a device that provides combustion-supporting air at a certain temperature for the blast furnace. It is an important auxiliary production equipment for the blast furnace and the main consum...
