Embodiment 1

[0071] Example 1: An example of independent operation of steelmaking and continuous casting schedules

[0072] As shown in Figure 1, the production plant in this example has three converters, 1#, 2#, and 3#, 1 argon blowing station, 2 LF furnaces, 1 RH, and 2 continuous casting machines.

[0073] 1. Basic data layer maintenance

[0074] The user first selects the name of the layered data to be maintained, and then enters the layered parameters needed to extract the layered data, and the system automatically exports the standard layered data to the layered data maintenance interface according to the contents of the layered parameters. Then the user enters and modifies layer data through the layer data maintenance interface. The specific content of the basic data is described in item 2 of the content of the invention in the description.

[0075] For example, in this example, the user requests that the target casting speed of the continuous casting machine need to be changed fr...

Embodiment 2

[0089] Example 2: An example of embedding the running schedule of steelmaking and continuous casting into a third-party system

[0090] As shown in Figures 1 and 2, the production plant in this example has three converters, 1#, 2#, and 3#, 1 argon blowing station, 2 LF furnaces, 1 RH, and 2 continuous casting machines. Complete production planning management system, its relational database is oracle9i, but the third-party system lacks the computer-aided guidance part of steel supply rhythm, the present invention can be embedded in this management system, and realize the scheduling of steelmaking and continuous casting steel supply rhythm automation.

[0091] 1. Embedded in third-party systems

[0092] According to item 6 of the content of the invention in the description:

[0093] 1) Understand that the service name of the oracle9i database in the third-party system is ora, and the server name is steel_server, and use the tools provided by oracle to create a network service ...

Abstract

A dispatch module using computer to assist and guide rhythm of steelmaking is prepared for accurately calculating planed time and reasonable error time of each furnace batch being on-line and being planed to be on-line at each process point to form operation-running time schedule of each furnace batch, using TCP / IP internal communication mode to collect actual variation information of each furnace batch in real time for dynamically updating said running schedule, storing production rhythm information into databank periodically and leading out data.

Description

technical field [0001] The invention belongs to computer technology, in particular to a computer-aided technology for instructing steelmaking and continuous casting production. Background technique [0002] On the one hand, most of the current production organization of the steelmaking plant adopts the empirical model, that is, the dispatcher estimates the process time of the online furnace according to his own production experience and actual production, and contacts the operators of the relevant operation rooms by telephone to guide the online furnace. running. In the experience mode, the dispatcher needs to manually contact and calculate the time of each process of each furnace on the line, which is likely to cause scheduling errors caused by human factors, resulting in chaotic production organization, so that the production capacity of the equipment cannot be maximized. [0003] On the other hand, many steel mills have introduced relatively advanced production managemen...
