Embodiment

[0069] Step 1. Get model parameters

[0070] The unit production line structure of this embodiment is as follows figure 2 As shown, it consists of 1 steel-making continuous casting unit, 1 hot rolling unit, 2 pickling-rolling units, 3 hot-dip galvanizing units and 2 continuous annealing units. There are a total of 5 flow directions, respectively P1, P2, P3, P4, P5 indicate that, taking the flow direction of P1 as an example, the processing path corresponding to the flow direction of P1 is M1 (steel making and continuous casting) -> M2 (Hot Rolling Mill)-> M3 (1# pickling mill)-> M5 (1# hot-dip galvanizing unit). Correspondingly, the M5 unit is the finished unit in the direction of P1. The inventory in the direction of P1 refers to the inventory of the work in progress between the M1 and M5 units. The sum of the stocks of pickled coils, the rest of the flow is similar.

[0071] The calculation of the distribution of steel-making needs to obtain basic data such as the production ca...

Abstract

The invention relates to a steelmaking quantity distribution control method for steelmaking continuous casting planned logistics flow direction setting. The method includes: establishing a steelmakingquantity distribution linear programming model; accurately calculating the steelmaking distribution quantity meeting the flow direction requirements of downstream procedure logistics in the steel production process; evaluating and adjustinga steelmaking quantity distribution scheme according to user requirements; and issuing the steelmaking quantity distribution scheme to a steelmaking continuouscasting planning system. Accurate flow direction setting can be provided for a steelmaking continuous casting plan, and the problems that a manual setting mode is extensive and difficult to quantizeare solved.

Description

Technical field [0001] The invention relates to a steelmaking volume distribution control method based on a steelmaking continuous casting planned logistics flow direction. Background technique [0002] Iron and steel production is a typical long-process industry. The main production processes include ironmaking, steelmaking, continuous casting, hot rolling, cold rolling and other processes. First, the iron in the iron ore is reduced from the oxides by the blast furnace to become liquid molten iron; then, the molten iron is loaded into the torpedo car and transported to the converter. After oxygen blowing, decarburization, and alloy addition, the molten iron The content of C, Mn, S, P and other elements is adjusted to the specified range and reaches a certain tapping temperature to become molten steel; then, the molten steel is transported to the continuous caster through the ladle and cast into a solid slab of predetermined specifications; After the slab is heated by the heatin...
