Embodiment Construction

[0063] In view of the problem in the prior art that the method for establishing a gas consumption prediction model based on a hot blast stove group has a very limited scope of application, an embodiment of the present invention provides a method for establishing a gas consumption prediction model based on a hot blast stove group. The process flow of the method Such as figure 1 As shown, the execution steps are as follows:

[0064] S11: Obtain historical data of the hot blast stove group.

[0065] When the hot blast stove group continuously supplies air to the blast furnace, it will record the historical data of the hot blast stove group, which includes the gas consumption of the hot blast stove group at each sampling time and the status of each hot blast stove in the hot blast stove group. Gas is consumed only when the hot blast stove is in the burning state, so it is necessary to obtain the status of each hot blast stove.

[0066] S12: Determine the combustion state cycle p...

Abstract

The embodiment of the invention discloses a gas consumption prediction model establishing method and device based on a hot blast stove group. The gas consumption prediction model establishing method comprises the steps that historical data of the hot blast stove group are obtained; according to the obtained state of each hot blast stove at each sampling moment, the combustion state circulation period of the hot blast stove group and the hot blast stoves which conduct combustion in one combustion state circulation period are determined; the historical data are divided according to the combustion state circulation period, and historical data within the combustion state circulation periods before the last combustion state circulation period are used as a training set; the gas consumptions at the identical sampling moments of the combustion state circulation periods in the training set are determined as original data sequences of the corresponding sampling moments respectively; an average value model is used as a gas consumption prediction model within a transition time period; according to the original data sequence of each sampling moment within non-transition time periods and a gray model, a gas consumption prediction model at the corresponding sampling moment is determined. The gas consumption prediction model establishing method and device are wide in application range.

Description

technical field [0001] The invention relates to the technical field of metallurgy automation, in particular to a method and device for establishing a gas consumption prediction model based on a hot blast stove group. Background technique [0002] The iron and steel industry is an industry with high energy consumption, high pollution, and high emissions. Energy saving and consumption reduction have always been one of the severe problems facing the iron and steel industry. In the iron and steel industry, blast furnace ironmaking is usually used, and blast furnace ironmaking is a continuous operation. In order to meet the demand for continuous high-temperature hot air in the blast furnace ironmaking process, generally 3 to 4 hot blast stoves are used to alternately supply air to a blast furnace. The furnace is composed of a hot blast stove group. The number and time of daily furnace replacement in the hot blast stove group are determined according to the number of hot blast sto...
