Problems solved by technology

However, the production planning system of this application has the disadvantages that the actual operation is relatively complicated and the feasibility is not high
[0005] Silicon steel products were once known as "handicrafts in steel products". Because of their particularity, no one has yet designed the steelmaking-continuous casting production plan for silicon steel.
At the same time, the production cycle of silicon steel is long, the production lines are many, the process is long, and the customers are small and scattered, and the needs of customers are more diversified and personalized. The main characteristics of contract orders are multi-variety and small batches.

Embodiment 1

[0074] combine figure 1 , the silicon steel production planning system of the present embodiment produces silicon steel according to the following steps: step one, blast furnace ironmaking; step two, molten iron desulfurization, in step two, the sulfur content in molten iron is reduced to below 0.005% wt; For smelting, the top-bottom composite blowing is adopted in step 3, so that the carbon content is reduced to below 0.06%wt; step 4, refining outside the furnace, vacuum treatment is adopted in step 4, and the carbon content is reduced to below 0.01%wt; step 5, continuous casting. Among them: the following conditions are met in the process of controlling silicon steel making and continuous casting:

Abstract

The invention discloses a silicon steel production planning system, and belongs to the field of steel production planning. According to the silicon steel production planning system, in the silicon steel making controlling and continuous casting process, A and B meet the equations (the equations can be seen in the description), wherein A is smaller than or equal to 10, and B is smaller than or equal to 12. According to the silicon steel production planning system, the equations 1 and 2 are met at the same time, and the coordinative optimization of process batched planning before and after steelmaking and continuous casting in silicon steel production is realized.

Description

technical field [0001] The invention relates to the field of iron and steel production planning, and more specifically relates to a silicon steel production planning system. Background technique [0002] Production planning and scheduling optimization is an important way for iron and steel enterprises to improve production efficiency, product quality and market competitiveness. Steelmaking and continuous casting are important processes in steel production, which are located in the upstream of the entire production process. The furnace schedule and casting schedule have a great impact on the production efficiency and production efficiency of the entire enterprise. Moreover, because steelmaking and continuous casting are closely connected in technology and affect each other in production scheduling, the coordination between the two must also be considered when formulating steelmaking production plans and continuous casting production plans. [0003] At present, scholars at ho...
