The invention discloses a cross-tapping control method of a blooming furnace group. The method comprises the following steps: Step 1. Determine the expected burning time of each batch of steel ingots in the soaking furnace group, and follow the sequence of the expected burning time Sorting in order to obtain the expected firing time sequence of steel ingots; step 2, determining the estimated burning time of the steel billets of each batch of heating furnace, and sorting according to the sequence of the estimated burning time to obtain the estimated burning time sequence of the steel billet; step 3. Determine the cross-tapping sequence of heating furnace billets and soaking furnace group steel ingots; Step 4. Determine the estimated tapping time of heating furnace billets and soaking furnace group steel ingots; Step 5. Cross-tapping control of steel billets and ingots; Step 6. Tapping Rhythm-time adaptive learning. Through the control method for cross tapping of the blooming furnace group of the present invention, the cross production of the blooming furnace group can be effectively controlled, the smooth production of the blooming furnace group is ensured, 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...
