Embodiment Construction

[0054] The following takes a blast furnace-hot metal pretreatment-converter-LF furnace-continuous casting production line as an example to illustrate that the present invention can dynamically schedule and direct production online according to the actual situation of the production site. The production line includes: 2 blast furnaces, 3 hot metal pretreatment stations, 3 converters, 3 LF refining furnaces, and 2 continuous casting machines. Among them, ladle transportation is used for the transportation from blast furnace to molten iron pretreatment. Production adopts a one-to-one model, that is, one blast furnace to one molten iron pretreatment to one continuous casting machine.

[0055] Assuming that the current time is 8:00, 1# continuous casting machine is pouring a furnace of molten steel that is expected to be poured at 8:15; 2# continuous casting machine is in the maintenance state, and it is estimated that the maintenance will be completed and pouring will start at 8:3...

Abstract

The invention discloses an iron-making and steel-making continuous casting integrated dispatching system, and belongs to the planning and dispatching field of iron-making and steel-making continuous casting production. The dispatching system comprises system implementing conditions and four sub-modules, wherein the system implementing conditions comprise equipment state and data acquisition programs, a database server, a database management program, database software and a client application program; and the four sub-modules comprise a torpedo ladle and foundry ladle dispatching planning and blast furnace area-converter area molten iron planning matching model module, an iron-steel interface molten iron dispatching framework module, a molten iron pretreatment-continuous casting dispatching module and an information communication module. Iron-steel interface torpedo ladle dispatching is implemented by monitoring the equipment state, judging the abnormal condition of the production, recording the operation performance, combining the setting parameters of dispatching personnel and establishing a blast furnace area-converter area molten iron planning matching model; static dispatching of a molten iron pretreatment-continuous casting section is generated by adopting a heuristic algorithm, and dynamic dispatching is implemented by using a hybrid genetic algorithm; and quick and flexible on-line dispatching of the molten iron pretreatment-continuous casting section is implemented.

Description

technical field [0001] The invention belongs to the field of ironmaking, steelmaking and continuous casting production planning scheduling, and in particular provides an integrated scheduling method of ironmaking-steelmaking-continuous casting, which realizes fast and flexible online scheduling from ironmaking to continuous casting. Background technique [0002] Ironmaking-steelmaking-continuous casting is an important link in steel production. The molten iron produced by the blast furnace is transported to the converter by torpedo cans or ladles, and the molten steel produced by the converter is transported by the ladle, refined outside the furnace, and then sent to the continuous casting machine. Ironmaking-steelmaking-continuous casting production is different from the upstream process of the blast furnace and the downstream process of the continuous casting machine, which have an intermediate warehouse, and this section has certain production requirements for the tempera...
