Ladle Refractory Defect Detection

In the steel - making process, the ladle is an important equipment for carrying high - temperature molten steel. The performance of the refractory lining (refractories) directly affects the service life of the ladle and the quality of the molten steel. However, during long - term use at high temperatures, refractories may develop defects such as cracks, spalling, and local overheating, posing a threat to the safe operation of the ladle. Real - time monitoring of the ladle using an infrared thermal imager can quickly detect refractory defects, prevent safety accidents, and extend the service life of the equipment.

Project Application

Non - contact Temperature Measurement: It is not necessary to touch the high - temperature ladle. Monitoring can be carried out from a long distance, ensuring safety.

Real - time Online Monitoring: Achieves dynamic monitoring of the ladle temperature, helping to quickly detect and handle potential problems.

High - resolution Temperature Images: Accurately identifies areas with abnormal temperatures, clearly showing the location and extent of refractory defects.

Data - supported Preventive Maintenance: By analyzing the temperature change trend, it helps to formulate a reasonable maintenance plan, reducing downtime and maintenance costs.

Improvement of Molten Steel Quality and Equipment Safety: Prevents molten steel contamination and safety accidents caused by refractory defects, enhancing production efficiency and the reliability of equipment operation.

Monitoring of Local Overheating of Refractories: Local overheating of refractories may be caused by wear of lining bricks, material degradation, or abnormalities in the cooling system. The overheated areas are prone to becoming risk points for molten steel leakage. Functions of the Infrared Thermal Imager: Through the surface temperature distribution map, the infrared thermal imager can accurately detect areas with abnormal temperatures on the inner and outer walls of the ladle. It conducts real - time monitoring of overheated parts, helping engineers deal with the problems in a timely manner and avoiding potential safety hazards.

Application effect

Online monitoring of the defects in ladle refractories through a thermal imager can effectively enhance the safety and economic efficiency of equipment operation, providing reliable technical support for the steel - smelting process.
