Basic automation control system for tandem cold rolling unit with five frames

Abstract

The invention provides a basic automation control system for a tandem cold rolling unit with five frames, which comprises a PLC (programmable logic controller ) cluster, an HPC (high performance computing ) controller cluster, a field rolling mill control console, a real-time data acquisition system, a developing and debugging system and a system communication network. By the basic automation control system, automatic roll changing can be realized, roll changing time is shortened, production and maintenance can be carried out easily, and building investment and maintenance cost are reduced greatly. Since a high-speed closed-loop control function is realized, continuously high-speed production on sites is guaranteed. Since a high-speed data acquisition function is realized, the basic automation control system is capable of running safely and efficiently and meeting the requirements to millisecond-level monitoring data during fault analysis of the high-speed closed-loop control system of the tandem cold rolling unit. Since functional units are debugged and controlled to run successfully, structural uniformity of the basic automation control system after modification of programs is guaranteed. The high-speed optical fiber memory map net serves as the communication network, high-speed data exchange is realized by data caching among functional units of the HPC controller cluster, and accordingly high-speed data acquisition of the real-time data acquisition system is realized.

Description

technical field [0001] The invention belongs to the field of basic automatic control of cold rolling, and in particular relates to a hardware configuration composition of a basic automatic control system suitable for a five-stand continuous cold rolling mill. Background technique [0002] With the rapid development of modern computer technology, contemporary cold-rolled strip production has achieved a high degree of automation, continuity and high precision. Due to the higher and higher requirements for the quality of cold rolled sheet, computer control system has become an indispensable part of cold rolling, especially cold continuous rolling. With the wide application of hydraulic control systems and the fact that most of the main control functions of the production line are focused on the control of the deformation zone formed by the roll-rolled piece, the basic automatic control system for cold tandem rolling has the following two characteristics: [0003] 1. High speed...

Problems solved by technology

[0013] At present, the basic automatic control system of cold rolling mills used in domestic cold rolling mills is generally a complete set of imported equipment imported from abroad. Although it has the characteristics of high automation and stable system control, the existing major foreign electric companies The basic automation control system provided by the rolling production line is relatively large in scale, with many components and complex system structure, which not only greatly increases the user's investment cost, but also prolongs the construction and commissioning preparation cycle, resulting in slow results and long investment recovery period.

At the same time, since spare parts still need to be imported, maintenance and repair are difficult, which not only increases the cost of equipment maintenance, but also has serious defects that affect production due to the long delivery time
