Embodiment 1

[0076] The first embodiment provides a method for formulating a dynamic production schedule for steelmaking with multiple processes and multiple units. According to information such as steel grades, the standard cycle of each process is set, and the time of each stage is calculated from the opening of the converter to the end of casting, and the production schedule is formulated. , so that each process can be executed strictly according to the production time node, instead of manual calculation and offline communication, improve the matching accuracy of furnace machines, reduce labor intensity, ensure the stable connection of upstream and downstream processes, and improve production efficiency.

[0077] like figure 1 As shown, a method for formulating a dynamic production schedule for steelmaking with multiple processes and multiple units provided in this embodiment includes the following steps.

[0078] S101, obtain production planning information.

[0079] Obtain production...

Embodiment 2

[0135] Based on the timetable formulation method of the first embodiment, the second embodiment provides a multi-process multi-unit dynamic production method for steelmaking, such as image 3 Shown is a schematic diagram of the principle of the method, including the following steps.

[0136] Step 1, obtain production planning information and pouring schedule from MES system;

[0137] Step 2, after confirming that the pouring schedule is correct, formulate a timetable based on the method of Embodiment 1, and prepare a furnace schedule;

[0138] The second step is to issue the furnace schedule.

[0139] Send the heat plan to the steelmaking automation system to control the on-time production of the furnace.

[0140] The method can be realized by the system, and realizes the maintenance of basic information, including the maintenance of production plan information, the set standard cycle of smelting process and the ladle logistics cycle between processes, and the operation stat...

Abstract

The invention relates to the field of steelmaking production, and particularly discloses a steelmaking multi-process multi-unit dynamic production method and a production timetable making method. Setting a smelting process standard period and an inter-process steel ladle logistics period according to the production plan information, and calculating a continuous casting process period; and according to the smelting procedure standard period, the inter-procedure steel ladle logistics period and the continuous casting procedure period, the procedure unit plan time is calculated. The method replaces the current manual calculation of the process period and the production time, replaces the current offline communication production organization mode, solves the problems that the process heat information cannot be dynamically monitored and shared in real time and the furnace machine matching is not accurate enough in the existing production organization process, reduces the labor intensity, guarantees the stable connection of the upstream and downstream processes, and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of steelmaking production, in particular to a multi-process multi-unit dynamic production method for steelmaking and a method for formulating a production schedule. Background technique [0002] Steelmaking is a key process in steel production, including converter, refining, continuous casting and other processes, and the processes are parallel with multiple units. Different steel grades use different process paths, and the process units are cross-connected with each other. The steelmaking production organization has different characteristics. The core of certainty is reasonable operation planning and precise scheduling, and the focus is on the adjustment of the process path and the unit and the time control of the ladle in the unit and the process path. [0003] The steelmaking automation system can only monitor the status of the unit in this process. Although the MES manufacturing execution system has the integrated...
