Product Description

LAG-S200 Ladle Slag Detection System Vibration Type


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 MC 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 the number of continuous pouring furnaces

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 number of continuous casting furnaces, it’s necessary to detect and control the slag in the later stage of continuous casting ladle casting.

The Working principle of the system

The LAG-S200 continuous casting ladle slag automatic monitoring system detects the slag state during the pouring process by receiving the vibration signal of the mechanical operating arm of the ladle nozzle. In the process of molten steel pouring, when molten steel flows through the long nozzle and pours into the tundish, the molten steel impacts the wall of the long nozzle and causes the vibration of the mechanical operating arm used to support the long nozzle. Since the specific gravity of the steelmaking slag is less than half of the specific gravity of the molten steel, it floats on the surface of the molten steel, and the steelmaking slag appears when the molten steel is about to be all poured. At this time, due to the high viscosity and poor fluidity of light steelmaking slag, the impact force of the mixed flow of molten steel and steel slag on the wall of the long nozzle is quite different from that of pure molten steel. The system mainly monitors the ladle slag of the continuous casting by measuring and analyzing the vibration difference of the mechanical operating arm.

The vibration signal is connected to the operation control unit of the system control cabinet through the front-stage conditioning and amplification module through the sensor installed in the middle of the operating rod. After processing, it is output to the industrial computer for operation and analysis. The slag signal detected by the system is output from the system control cabinet to the front-end control unit, and then control the alarm horn and alarm light to work, or issue an instruction to close the ladle nozzle.

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.

6 The equipment adopts a modular design. The failure of each module will not affect other parts, which ensure more reliable operation of the system and easy maintenance.

7 The alarm display device is used on site to visually indicate the flow state of molten steel and slag. When slag is unloaded, we can choose to automatically close the ladle nozzle or sound and light alarm at the same time, prompting the on-site operator.
