Problems solved by technology
The continuous casting and rolling of medium and thin slabs belongs to the short-process rolling. After being cut by the flame cutting machine, the casting slab is directly transported by the roller table to the continuous rolling heating operation area. The time is very short. In addition, various variable factors in the overall production line Many, making production planning very difficult and difficult to implement
In the actual production process, due to the randomness of medium and thin slab continuous casting and rolling production, unplanned production often occurs, which affects the management and delivery of finished products
In addition, because the quality control data cannot be fed back in time, the product quality cannot be guaranteed
Therefore, the existing medium-thin slab continuous casting and rolling production control model can no longer adapt to the complex production conditions of multiple casters, multiple streams, different casting speeds, and continuous casting of different steel types

Embodiment Construction
[0019] The following takes the control model produced by Angang 1700 medium thin slab continuous casting and rolling production line as an example, combined with the attached figure 1 The implementation steps of the present invention are described in detail with accompanying drawing 2.
[0020] 1. First, carry out slab design for the production contract that meets the requirements of quality system 1. The result of slab design 2 is to decompose the contract into estimated slab information (virtual slab), which is the basic information in the entire production control system. unit, and subsequent processes organize production based on estimated slab information.
[0021] 2. After the design of the virtual slab 2 is completed, the monthly plan 3 and the weekly plan 4 are finally incorporated into the daily plan
[0022] 3. Mark 5. The compilation of daily plan 5 takes the rolling cycle as the unit, and formulates the 24-hour production plan for the day according to the actual ...

The present invention provides a thin and medium slab continuous-casting and continuous-rolling production control model. It is formed from computer control system and data processing system, in which said data processing system mainly includes the submodules of quality design system, slab design, manufacturing program design of a month, manufacturing program design of a week, manufacturing program design of a day, working out steel-smelting production program, working out continuous casting pouring frequency program, working out continuous casting blank-discharging programand working out continuous rolling program. Said invented model can integrate the processes of smelting, continuous casting and rolling into one body.
Description
technical field [0001] The invention belongs to the field of computer application, and particularly relates to the control technology of continuous casting and rolling production of medium and thin slabs. Background technique [0002] In metallurgical enterprises, the existing medium and thin slab continuous casting and rolling production control model organizes production according to the maximum production capacity of the continuous casting machine, and the planning and dispatching personnel formulate plans and guide production according to the recent contract situation. The continuous casting and rolling of medium and thin slabs belongs to the short-process rolling. After being cut by the flame cutting machine, the casting slab is directly transported by the roller table to the continuous rolling heating operation area. The time is very short. In addition, various variable factors in the overall production line There are many, which makes it very difficult to formulate pr...
