Abstract

The invention discloses an automatic control system for a moderate-thickness plate roller quenching machine, and belongs to the technical field of heat treatment automatic control. The system consists of a PLC (Programmable Logic Controller) and interface system, a process control system and a track communication system, and is characterized in that: 1, water spray parameters are accurately controlled by using an intelligent algorithm to realize flow and pressure double-closed-loop control; 2, calculation is performed through procedure distribution, function trigger and quenching parameters to realize high-accuracy temperature control, plate shape control and model self-study; 3, a communication intermediate packet developed on the basis of TCP / IP (Transmission Control Protocol / InternetProtocol), OPC (Optical Proximity Correction) and PROFIBUS-DP can realize smooth data connection of the quenching machine and the MES (Manufacturing Execution System) as well as upstream and downstream equipment and meanwhile realize accurate transfer of data between subsystems; and 4, a trigger mechanism is adopted to realize queue macro tracking and position micro tracking of a steel plate of aquenching region. By adopting the system, the problems of complex control and low control accuracy of the roller quenching machine are solved well, and automatic and one-key operation of the roller quenching machine is realized.

Description

technical field

[0001] The invention relates to the field of automatic control of heat treatment process, in particular to a medium-thick plate roller quenching machine equipment and process automatic control system. Background technique

[0002] The medium-thick plate roller quenching machine has high cooling intensity, complicated process technology, and great difficulty in controlling the quenching process. Relevant equipment, processes and control systems have been monopolized by a few foreign companies for a long time, resulting in my country's plate quenching equipment and technology being completely dependent on imports before 2008. The imported equipment control system puts too much emphasis on the direct, stable and reliable control of the online control unit, ignoring the logical control and quick response of the PLC system, the precise automatic control of the process, the accurate and reliable operation of the tracking communication system, and the scientific man...
