Steel rolling rotational flow pool liquid level real-time monitoring and automatic control system

Abstract

The invention discloses a steel rolling rotational flow pool liquid level real-time monitoring and automatic control system which comprises radar liquid level meters, a PLC, an HMI control computer and four lifting pumps, the two radar liquid level meters are the first radar liquid level meter and the second radar liquid level meter respectively, and the four lifting pumps are connected with the PLC. The lifting pumps comprise a first lifting pump, a second lifting pump, a third lifting pump and a fourth lifting pump, the first radar liquid level meter and the second radar liquid level meter are both in signal connection with the PLC, the PLC is in signal connection with the HMI control computer, and the first lifting pump, the second lifting pump, the third lifting pump and the fourth lifting pump are all in signal connection with the PLC. The steel rolling rotational flow pool liquid level real-time monitoring and automatic control system has the advantages that the actual condition of the liquid level in the rotational flow pool can be detected in real time, and automatic control can be achieved.

Description

technical field [0001] The invention relates to the technical field of automatic control of a steel rolling swirl pool, in particular to a real-time monitoring and automatic control system for the liquid level of a steel rolling swirl pool. Background technique [0002] In the steel rolling production process, the rolls, roll rings, water tanks and other parts need turbid ring water for cooling. The generated turbid ring water is recovered through the steel rolling swirl pool, and the turbid ring water is sent to the energy water station for chemical treatment by the lift pump. Utilization, so the steel rolling swirl pool equipment is the key equipment of the production process. At present, the high-line, first-bar, and second-bar rolling mills of Yangchun New Iron and Steel Co., Ltd. all use shaft barrel swirl pools, and the control mode is manual monitoring operation mode. The third-line swirl pools of the rolling mill are equipped with 4 lift pumps. During normal producti...

AI Technical Summary

Problems solved by technology

At present, the high-line, first-bar, and second-bar rolling mills of Yangchun New Iron and Steel Co., Ltd. all use shaft barrel swirl pools, and the control mode is manual monitoring operation mode. The third-line swirl pools of the rolling mill are equipped with 4 lift pumps. During normal production, 2 lift pumps are turned on, and the post personnel monitor the liquid level of the inner swirl pool according to the observation video. When the liquid level is high, 4 lift pumps are manually started to pump water. When the liquid level is low, 1 set is manually stopped. Pump, if the liquid level is lower, manually stop 2 pumps, so there is a big hidden danger:

[0003] First, the post personnel cannot monitor the actual situation of the liquid level in the whirl pool in real time;

[0004] Second, the lifting pump of the swirl pool did not realize automatic control, which increased the labor intensity of the personnel on the post, and also increased the probability of accidents;

[0005] Third, thirdly, the diameter of the shaft barrel type swirl pool is small, the capacity is small, and the water temperature in the pool fluctuates greatly. Especially in autumn and winter, during the continuous production process, the water surface and the inner platform of the swirl pool will generate a lot of water vapor, which will cause The manual video monitoring operation mode is vague, and the traditional float level control mode and single radar level gauge control mode signal failure affects the use and causes accidents
