Control system of continuous rolling mill

Abstract

The invention discloses a control system of a continuous rolling mill, which comprises an I / O tank (2), a continuous rolling mill unit (4) and a data line (5); the system also comprises a remote control terminal (1) and a receiving / transmitting device (6); the remote control terminal (1) transmits signals to the receiving / transmitting device (6) by a wireless transmission line; the receiving / transmitting device (6) processes and converts the signals and then transmits the signals to the I / O tank (2); and the I / O tank (2) transmits the control signals to each function block of the continuous rolling mill unit (4), thus realizing the remote control on site. As wireless transmission is adopted, the on-site operation desk and the cables between the operation desk and the I / O tank (2) in the traditional operation system are removed, the equipment investment is reduced and the workshop area is saved.

Description

technical field [0001] The invention belongs to the technical field of physics, and relates to an industrial control system, in particular to an on-site control system of a continuous rolling mill. Background technique [0002] In the modern metallurgical industry, the continuous rolling mill is the most important equipment in the workshop. Operations such as replacement and maintenance of the continuous rolling mill are often required, and the on-site operation procedures are very complicated, such as rolling mill clamping / unclamping, flat in / out, Up / down, roll gap increase / decrease, clutch opening / closing, coupling engagement / disengagement, etc., and the operating device also occupies a lot of workshop space. Traditional on-site control systems of continuous rolling mills such as figure 1 As shown, the on-site operation console 3, the PLC I / O box 2 and the continuous rolling unit 4 are connected and communicated through a cable 5. During on-site control, the worker opera...

AI Technical Summary

Problems solved by technology

The on-site operation platform 3 cannot be too close or too far away from the continuous rolling unit 4, too close will hinder the continuous rolling unit 4 roll changing, maintenance and other movement operations, and too far is not convenient for the operator to observe the site, so the on-site operation platform 3 is often installed In the middle of the channel where cranes are often adjusted and installed, and there are multiple on-site operating platforms 3 on a production line, it is very unfavorable to the safety of the operating platforms. In actual design, the operating space in front of the continuous rolling mill is often increased, that is, the span of the entire workshop is increased. , despite this, the on-site operation platform 3 is often damaged by the rolling mill transfer

This will lead to a larger increase in project occupation and investment
