Construction method for simulation system based on hot-rolling L2 process control system

Abstract

The invention provides a construction method for a simulation system based on a hot-rolling L2 process control system. The method comprises the steps: S1, equipment selection of the simulation system,network design and application work platform integration; S2, deployment of all regional subsystem modules of the simulation system, wherein each regional subsystem includes a heating furnace system,a rough rolling system, a finish rolling system, and a laminar cooling system; S3, design of a parallel mode of the simulation system and processing of a parallel message; S4, data management of a simulation process, installation of database software, management of process data; S5, design of an L2 communication system and an L1 communication interface, and achieving of a purpose that the simulation system receives L1 actual strip steel data in real time. The simulation system of the invention can provide a stable, reliable, real and effective test environment and can ensure the successful use of the functions once, and the new function can be directly debugged and tested on the simulation system, and the rolling line production is not affected, thereby reducing the halt production and steel waste of a rolling line, and improving the progress of functional use.

Description

Technical field: [0001] The invention relates to a method for building a simulation system based on a hot-rolling L2 process control system, and belongs to the technical field of hot-rolling control. Background technique: [0002] The hot rolling L2 process control system is closely related to hot rolling production, directly related to the stability of production, product output and quality. With the further improvement of the company's output and quality requirements, and the needs of the company's product expansion, the application and model functions of the L2 process control system involved in production control often need to add, modify, optimize, etc. according to the requirements of the hot rolling process. . For a long time, before the new function is put into use, the rolling line must be shut down, and then repeatedly debugged and tested on the online L2 system to ensure that the new function is normal before it is put into production. On the one hand, this take...

Problems solved by technology

On the one hand, this takes up a lot of production time, affects the output of hot rolling, and also affects the progress of functional commissioning. For example, the process urgently needs to roll new products, and the new function test is not comprehensive enough, which leads to scrap steel and production shutdown failures when it is put into online production and use.

On the other hand, when debugging and testing new functions on the online system, some new functions are complex and involve the nesting and modification of databases, models, applications, etc. When this function is tested on the online system, the database, Model and application changes have caused major risks to the stability of the online system

In addition, the time for testing new functions is limited when the rolling line is shut down, and the new functions cannot be fully tested. Sometimes, after the new functions are put into use, the rolling line will be shut down and scrap steel will be scrapped.
