Method for reforming two-stage control system of old rolling mill

Abstract

The invention discloses a method for reforming a two-stage control system of an old rolling mill. The method comprises the steps that the two-stage system composed of a two-stage server and two or more two-stage clients is additionally arranged on the basis of a first-stage control system, the two systems are subjected to data exchange through the Ethernet, a sub-control system in the first-stagecontrol system is reformed to be used for automatic data acquisition and integration of all the control systems and automated replacement of manual operation equipment, temperature detection is addedinto transmission control and thickness control operation to form temperature closed-loop control, and tree topology structures are formed between the two-stage server and the two or more two-stage clients wirelessly or in a wired mode. According to the method, information integration is conducted on the original old rolling mill, the two-stage system is additionally arranged, automatic reformingof the old rolling mill and automatic production are achieved, the using time of the rolling mill is prolonged, the rolling quality is improved, and the enterprise cost is lowered.

Description

Technical field: [0001] The invention relates to the field of rolling mills, in particular to a method for transforming an old rolling mill with a secondary control system. Background technique: [0002] Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. [0003] The modern automatic control rolling mill has multiple control systems, which can be divided into four levels according to the level, including the use of PLC, DCS and other control systems to control production according to the instructions issued by the second level, and realize the basic automation of the first level control system; Three-level data information, information processing and feedback, after generating the rolling table, the instruction is sent to the second-level control s...

Problems solved by technology

[0004] However, in the old rolling mills in the past, the operation is still in the state of manual operation by the operator. Even if there are some automatic control systems, they are independent of each other. Due to the incompatibility of each system, the data between the systems In the case of inconvenient exchange and personnel operating errors, the problem of increased production defect rate
