Abstract

The invention provides a stove changing method for blast-furnace hot blast stoves. The method comprises the following steps of collecting operation data of the blast-furnace hot blast stoves; classifying the stove changing types of the blast-furnace hot blast stoves in combination with the number of blast furnaces according to a result of collecting the operation data of the blast-furnace hot blast stoves; and computing stove changing time of the blast-furnace hot blast stove in combination with an analysis result of the operation data of the blast-furnace hot blast stoves according to a typeclassification result. According to the method in the embodiments of the present application, the hot blast stoves can run orderly and regularly.

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...
