Problems solved by technology
If the storage space is not well controlled and the process organization is unreasonable, insufficient material preparation will affect the blast furnace production; during the process, it is necessary to manually monitor the process status, the status of the material level in the silo, and manually switch the process, resulting in low efficiency and energy consumption; Sprinkling, throwing and other issues
The whole process requires manual intervention, high labor intensity, poor economic effect, and does not meet the requirements of future intelligent manufacturing. Therefore, a new solution is urgently needed to solve this technical problem

Embodiment 1
[0055] Embodiment 1: an intelligent control method based on multi-blast furnace raw fuel transportation logistics, the intelligent control method includes the following steps:
[0056]Step 1: Prepare daily work plan;
[0057] Step 2. Compile the model of material preparation for custom repair
[0058] Step 3: Designate the bin control plan;
[0059] Step 4: Process intelligent switching;
[0060] Step 5: The control method of the automatic trough movement of the trolley.
[0061] The first step: prepare daily operation plan, as follows,
[0062] According to the demand of each blast furnace for various materials, the material production plan within 24 hours is compiled;
[0063] For example, the calculation method of lump ore demand is as follows:
[0064] Assume that the 24-hour demand for a certain type of raw material for a single blast furnace is Q:
[0065] Q=R×i×K×λ=3200×2.3×1.61×17%=2014 tons / day
[0066] The number of refills required for this type of raw fuel i...

The invention relates to a multi-blast furnace based raw fuel conveying logistics intelligent control method. The intelligent control method comprises the following steps of S1, compiling a daily operation plan; S2, compiling a periodical repair material preparation model; S3, specifying a bin tank control plan; S4, performing flow intelligent switching; and S5, performing a method for controllinga trolley to automatically move to tanks. According to the method, through the establishment of models such as an operation plan management model, the periodical repair material preparation model, abin position real-time management model, and a flow intelligent switching model, a raw material system efficiently and orderly conveys materials to multiple blast furnaces, the operation plan is automatically generated, the periodical repair material preparation model is intelligently compiled, bin tank intelligent control and switching are achieved, flow intelligent control is achieved, it is guaranteed that all the blast furnace raw fuel bin positions are controlled at a reasonable level through a computer system in a full intelligence mode, stable and smooth operation of the blast furnacesis facilitated, and the operation strength is greatly reduced.
Description
technical field [0001] The invention relates to a control method, in particular to an intelligent control method based on multi-blast furnace raw fuel transportation logistics, which belongs to the technical field of intelligent manufacturing. Background technique [0002] In a large-scale iron and steel complex, multiple blast furnaces use a common raw and fuel delivery system for production and material organization. At present, operators are required to select the conveying process according to the blast furnace storage space and material preparation, and manually control the storage space. If the storage space is not well controlled and the process organization is unreasonable, insufficient material preparation will affect the blast furnace production; during the process, it is necessary to manually monitor the process status, the status of the material level in the silo, and manually switch the process, resulting in low efficiency and energy consumption; Sprinkling, fl...
