The invention discloses a cross steel tapping control method for a blooming furnace group. The method comprises the following steps: step 1, determining predicted firing times of various batch steel ingots in a soaking pit furnace group, and ranking according to the precedence of the predicted firing times so as to obtain a steel ingot predicted firing time sequence; step 2, determining the predicted firing times of various batch steel billets in a heating furnace and ranking according to the precedence of the predicted firing times so as to obtain a steel billet predicted firing time sequence; step 3, determining a cross steel tapping sequence of the steel billets in the heating furnace and the steel ingots in the soaking pit furnace group; step 4, determining the predicted steel tappingtimes of the steel billets in the heating furnace and the steel ingots in the soaking pit furnace group; step 5, controlling the cross steel tapping of the steel ingots and the steel billets; and step 6, carrying out steel tapping time adaptive learning. Through the cross steel tapping control method for the blooming furnace group, the cross production of the blooming furnace group can be effectively controlled, the production of the blooming furnace group is ensured to be smoothly carried out, and the energy consumption is reduced.
Description
technical field [0001] The invention relates to the technical field of metallurgical production, in particular to a cross-tapping control method for blooming furnace groups. Background technique [0002] The preliminary rolling plant of an iron and steel enterprise is generally organized around the preliminary rolling furnace group composed of a soaking furnace and a heating furnace. The preliminary rolling furnace group is composed of a heating furnace and multiple soaking furnaces. The throat of rolling is connected to the steelmaking process of intermittent production, and the steel rolling process of continuous production is connected to the bottom. [0003] figure 1 It is a schematic diagram of the blooming production process. As shown in the figure, the blooming production process includes two production processes. One is the electric furnace continuous casting production line, in which the electric furnace smelts 11 molten steel required by the process, and the molte...
