Ladle Slag Detection System

Overview

The continuous casting vibration type ladle slag detection device is used to detect the slag content of the ladle nozzle in the steelmaking continuous casting process, so as to improve the cleanliness of the tundish molten steel and obtain the best yield of the ladle molten steel. The device adopts the principle of vibration detection.

The LAG-S200 continuous casting ladle slag automatic detection system is developed by Wuhan CenterRise M&C Engineering Co., Ltd. after many years of research with many scientific research institutes, and fully combined with the actual situation on site. It has a real field application value as a continuous casting ladle slag automatic detection system.



The meaning of the system
1. Reduce the amount of tundish slag
2. Improve the purity of molten steel
3. Improve the life of the tundish
4. Reduce sliding nozzle erosion
5. Reduce nozzle blockage
6. Increase continuous pouring heats
7. Reduce the amount of residual steel in the ladle when high-quality steel is casting
8. Improve the yield of molten steel
9. Improve the quality of continuous casting billets

In order to improve the purity of the molten steel in the tundish, and improve the quality of the casting billet, especially to improve the quality of the billet in the transition section, and reduce the amount of residual steel in the high-quality ladle, and prolong the life of the tundish lining, and increase the continuous casting heats, it’s necessary to detect and control the slag in the later stage of continuous casting ladle casting.

The features of the system
(1) It is easy to install, basically no modification is made to the field equipment, and the installation and debugging work will not affect the normal production of the enterprise.

(2) The detection accuracy is high, and the effective rate is greater than or equal to 95%. The threshold of slag volume is accurately set, the output control function is powerful. It has excellent performance in technical indicators such as the sensor service life and sensor usage times.

(3) The sensor is installed at a position far away from the molten steel, and is cooled by a special refrigeration device for 24 hours. The outer layer adopts a composite protection structure, which has a long service life.

(4) Adopt professional and targeted signal processing methods to obtain the vibration characteristic parameters of the ladle slag, and analyze, reason and judge the effective slag signal through the vibration signal database, which has a high accuracy of slag alarm.

(5) The architecture is established based on the artificial intelligence network, which has the functions of self-learning and self-induction.
