Description

technical field [0001] The invention belongs to the technical field of iron and steel production planning and dispatching, and in particular relates to a steelmaking and continuous casting rescheduling system and method based on strong disturbances. Background technique [0002] The steelmaking and continuous casting production process is the core link in the production process of modern iron and steel enterprises, including three major processes: converter smelting, refining furnace refining and continuous casting machine casting. The production scheduling of steelmaking and continuous casting is based on the pouring plan. Under the known conditions of the production process path of the furnace and the continuous casting machine that the furnace is cast in the continuous casting process, the pouring is started on the continuous casting machine on time. The continuous casting of heats within a time, and the two adjacent heats processed by the same equipment can not cause ope...

Problems solved by technology

[0003] At present, the testing of the steelmaking and continuous casting production scheduling algorithm is mainly divided into three categories: the first category is offline testing of the steelmaking and continuous casting production scheduling algorithm, which is only a test of the algorithm function, that is, according to the input data To verify whether the correct planning and scheduling results can be obtained after algorithm processing (such as unit testing, integration testing, system testing, etc.), and does not test and analyze the advantages and disadvantages of the algorithm

The second type of situation is to conduct an online test on the steelmaking and continuous casting production scheduling algorithm in the actual production process, and send the scheduling result obtained after the scheduling algorithm to form an instruction to the production process to verify whether the planned scheduling result can guide the production correctly. The method does not test and analyze the advantages and disadvantages of the algorithm, but only verifies whether the scheduling result is applicable to the actual production process, and the long online test time also affects the actual application of the scheduling algorithm

The third type of situation is the simulation test of the production scheduling algorithm for steelmaking and continuous casting. This type of research is mainly to test and verify the pros and cons of the scheduling algorithm, but these methods do not compare the scheduling algorithm with the actual production process (or close to the actual production process). process) connected to carry out online testing, so that there are still many problems in the actual application process of the studied algorithm, which leads to the fact that the algorithm cannot be really well applied in practice.

To sum up, it can be seen that the steelmaking and continuous casting production scheduling algorithm has not been tested in the actual production process (or close to the actual production process) environment, so that the researched smelting Steel continuous casting production scheduling algorithm is difficult to effectively guide the actual production process
