Tundish temperature monitoring

Tundish Temperature Monitoring

In the continuous casting process, the tundish is a key device for storing and maintaining the temperature of molten steel. As the temperature of the molten steel changes, the refractories of the tundish (such as the lining and thermal insulation materials) are also affected by thermal stress, resulting in wear, cracks, or other damages. By using an infrared thermal imager for temperature monitoring, the working state of the tundish refractories can be evaluated in real - time, potential safety hazards can be detected, thereby improving production efficiency, reducing downtime due to malfunctions, and extending the service life of the equipment.

Project Application

Efficient Real - time Monitoring: Through non - contact temperature detection, the lining temperature of the tundish can be monitored in real - time, avoiding the limitations of traditional methods.

Accurate Fault Location: It can accurately locate the areas with abnormal refractory temperatures, helping workers detect problems in a timely manner and carry out repairs.

Refractory Performance Evaluation: Based on the real - time data of temperature distribution, the service status and remaining life of refractories can be evaluated, and replacement or repair plans can be planned in advance.

Enhanced Production Safety: It prevents molten steel leakage or production interruptions caused by refractory damage, improving the stability and safety of the production process.

Preventive Maintenance: Through early monitoring and diagnosis, sudden failures can be avoided, downtime can be reduced, and production costs can be lowered.

Tundish Refractory Temperature Distribution Detection: Use an infrared thermal imager to monitor the temperature distribution on the inner wall of the tundish, and promptly detect overheated areas of the refractories. Provide real - time temperature data to assist in judging the working condition of the refractories and evaluating the degree of refractory wear.

Temperature Abnormality Diagnosis: The infrared thermal imager can capture subtle temperature changes inside the tundish, and quickly identify areas with abnormal temperatures through thermal images. Analyze the temperature change trend to help predict the remaining service life of the refractories and carry out preventive maintenance.

Thermal Stress Monitoring and Crack Detection: The thermal imager can clearly identify cracks or damaged areas caused by thermal stress, and promptly detect potential malfunctions. Provide dynamic images of temperature changes to help maintenance personnel evaluate the impact of cracks on the overall performance of the refractories.

Application effect

Monitoring the tundish temperature with an infrared thermal imager enables the timely detection of refractory abnormalities during the production process and provides accurate temperature analysis. This, in turn, enhances the stability, safety, and economic benefits of the continuous casting process.
