Embodiment 1

[0301] Example 1 Optimal Scheduling of Silicon Steel Sheet Hot Rolling Production Line

[0302] After installing the system as above. Planners complete the hot rolling plan according to the following steps, and the operation process is shown in Figure 12:

[0303] 1. After the user starts the hot rolling optimization scheduling system, firstly enter the user name and password. If the user is an illegal user, he cannot enter the system; if the user is a legitimate user, he can enter the system smoothly, as shown in Figure 13.

[0304] 2. Click the "data download" button, and the system of the present invention downloads the original data from the current information system of the enterprise. See attached drawing 14.

[0305] 3. If a new slab arrives in the warehouse before hot rolling at this time, the information of the newly arrived slab should be added into the database. At this time, click the "Add" button, and a dialog box will pop up to fill in the added slab informati...

Embodiment 2

[0331] Example 2 Optimum scheduling of medium carbon steel hot rolling production line

[0332]Same as example 1 above, first download the data, configure the calculation parameters, choose to execute the automatic arrangement algorithm, check the results for violations, and finally upload.

[0333] Authorized users log in to the system.

[0334] Click the "data download" button, and the system of the present invention downloads the original data from the current information system of the enterprise.

[0335] The planner sets the calculation parameters for the system according to the characteristics of the medium-carbon steel to be processed: click "Configuration" -> "Calculation Parameter Configuration", and set the parameters under "Slab Specifications". The other two items are the same as those of silicon steel, see Figure 28.

[0336] Execute automatic preparation of hot rolling plan. The planner chooses the algorithm to use, here the CT_SS algorithm is used. Click "CT_...

Embodiment 3

[0340] Example 3 Optimal scheduling of non-ferrous metal (aluminum) hot rolling production line

[0341] In the previous two examples, we are on the hot rolling production line of iron and steel enterprises, according to the actual production process requirements, we have established a reasonable and effective hot rolling production planning example obtained by solving the hot rolling production planning model. The system of the present invention is equally applicable to both low carbon and high carbon steels. It is proved that the system and method of the present invention can effectively solve the preparation of ferrous metal hot rolling production plan.

[0342] Provide the example of the present invention for non-ferrous metal hot rolling production plan preparation below. Take aluminum as an example.

[0343] Use the steps of the above embodiment to set calculation parameters: click "Configuration" -> "Calculation Parameter Configuration", and set parameters under "Slab...

Abstract

A kind of optimized dispatching method for hot-rolled metal, which includes that it extracts the customer data and production data from data collection system and data center, and makes the hot-rolled production plan according to the built mathematical model of optimized production, and the characteristics are: the model is built according to the craft constraints and the hot-rolled cost, and the aims for undetermined plans and parallel hot-rolled plan is to minimize the production cost; (2)the solution of model adopts two kinds of hybrid algorism containing loop exchange algorism. It provides the hot-rolled dispatching optimized system and device based on said method, and the system is formed by combination of model design idea and graph interface, and the model construction module and model solution module are embedded in the auto production module for production plan; and the devices include PC, interface, router or switcher, and the complete software which consists of said functional module is mounted on the PC, and which is connected with the front end of hot-rolled control system by network or inner sever.

Description

technical field [0001] The invention belongs to the technical field of metal material processing information, relates to automation technology, in particular to a hot rolling production scheduling optimization technology and algorithm for production and application in the metallurgical industry. Background technique [0002] The hot rolling production scheduling of metal materials is the main content of the production management of metallurgical enterprises. The quality of scheduling is directly related to the production efficiency of the workshop, the quality of the product and the economic benefits of the factory. [0003] Take the steel mill as an example: the raw materials used for hot-rolled strip steel are mainly blooming slab and continuous casting slab. The strip billet rolled by the roughing mill is then refined on the finishing mill, cooled, coiled and finished after rolling. For the finish rolling process, the finish rolling unit generally consists of 6 to 7 stan...
