Background

Ladles and iron ladles are key containers for transporting and storing liquid metal (molten steel, molten iron), and are widely used in core processes such as ironmaking, steelmaking, refining and continuous casting. Infrared thermal imaging can monitor the temperature distribution of the ladle's refractory layer, warn of lining wear and local overheating, and assist in ladle life management and safe and efficient operation of the steelmaking process.

Solution Description

HIRDA-L steel ladle intelligent diagnosis and analysis system is a high-tech system specially used to detect the temperature of steel ladle shell and conduct intelligent analysis. The system consists of high-temperature IR thermal camera, high-definition visible light camera, electric control box, algorithm server and client management software. It centrally monitors and manages the equipment on the operation site, and realizes data collection, analysis, high temperature point positioning, automatic alarm and ladle number recognition through digital transmission network.

System Features

1. IR video camera with all-weather passive thermal imaging function；

2. Adopt self-developed temperature measurement and correction algorithm to achieve accurate temperature measurement；

3. Strong environmental adaptability, can be used in harsh environments such as high temperature and high dust；

4. Automatic identification of ladle numbers and intelligent association of temperature data；

5. 360° all-round temperature detection of the ladle, 3D schematic diagram showing the temperature distribution of the ladle；

6.  1 square decimeter high temperature area automatic positioning warning；

7.  Establish the corresponding model between the refractory material of the ladle and the surface temperature of the ladle；

8.  I cam establish a surface temperature database for each ladle life cycle;

9.  Open interface, providing SDK development kit, can be connected with DCS, PLC and other systems.

Benefits brought

• 

  Through thermal imaging to detect the temperature distribution of the ladle wall and ladle bottom, the wear, peeling or cracks of refractory materials can be found in advance, the risk of molten steel leakage can be prevented, and the service life of the ladle can be extended.

• 

  Dynamically monitor the surface temperature field of the ladle, evaluate the thermal insulation performance of the ladle wall, assist in adjusting the baking process, reduce the temperature drop during the transportation of molten steel, and ensure the temperature stability of the continuous casting process.

• 

  Monitor the temperature changes in the sliding nozzle area, timely detect temperature abnormalities caused by nodules, blockages or wear, avoid poor pouring or steel leakage accidents, and improve the success rate of continuous casting.
