Description

Technical Field

[0001] This invention belongs to the field of automatic control technology for continuous casting equipment, specifically relating to a method, system, terminal, and storage medium for controlling water distribution in a crystallizer. Background Technology

[0002] The crystallizer is a key component of continuous casting equipment, the heart of the continuous casting machine. It plays a crucial role in improving continuous casting productivity, maintaining normal production, and ensuring billet quality. The crystallizer is equipped with corresponding cooling water circuits as needed. Each cooling water circuit is equipped with flow meters, temperature sensors, pressure sensors, and regulating valves to monitor the operating status of each cooling water circuit and control the flow rate of cooling water within it.

[0003] Current automatic water distribution control systems cannot handle the following two situations: one is when the flow meter disconnects, in which case the flow meter will display zero, and the existing automatic water distribution control system will gradually increase the regulating valve, causing the actual water flow to far exceed the demand, resulting in serious quality problems in the cast billet; the other situation is when the flow meter displays full scale (maximum value) due to some kind of malfunction, in which case the existing automatic water distribution control system will reduce the opening of the regulating valve until it is closed, causing a water outage. This situation is the most dangerous and will have serious consequences. If it is not detected in time, it may even cause an explosion. This is a shortcoming of the existing technology.

[0004] In view of this, it is very necessary to provide a crystallizer water distribution control method, system, terminal and storage medium to solve the above-mentioned defects in the prior art. Summary of the Invention
