Solve the hidden safety hazards of inspection – new technology!

Safe production is the top priority of the steel industry. Infrared thermal imaging is used for predictive maintenance, early detection of potential safety hazards, and stifling accidents. As a non-contact temperature measuring instrument, thermal imaging cameras can quickly detect the thermal (temperature) distribution on the surface of objects by imaging and analyzing them. thermal defect.

To sum up, in the safety production of steel, thermal imaging cameras mainly have the following typical applications:

  • Ladle temperature detection
Thermal-imager

The left picture above is a ladle, and the right picture is a thermal image of the ladle. We can clearly see that the temperatures of Sp1 and Sp2 on the thermal image are both over 380°C, indicating that the residual thickness of the two ladle walls has become thinner and needs to be repaired. Replace the refractory brick lining at the slag line.

  • Converter refractory defect detection
Thermal-imager

When the converter works for a long time, the internal refractory materials will gradually be corroded and fall off, and the heat conduction speed of the worn part will be faster than that of the normal area.

Thermal-imager

The picture on the left shows the converter, and the thermal image of the converter on the right shows that the maximum temperature of the furnace bottom exceeds 400℃, which can objectively reflect the damage degree of the furnace lining.

  • Hot blast stove refractory temperature detection
Thermal-imager

Because of the arc shape of the hot blast stove, especially the dome part, the refractory bricks of the heat insulating material are prone to cracks and fall off during production. In severe cases, the shell may burn through and cause safety accidents.

The use of thermal imaging camera can quickly and accurately detect the damaged position of the dome lining, which is convenient for timely maintenance and ensures safe production.

  • Tundish penetration detection
Thermal-imager

Before the tundish piercing accident, the temperature of the outer steel shell of the tundish will rise abnormally. The accident of wearing a bag is a dynamic process and does not happen suddenly.

In this dynamic process, the thermal imager can monitor the tundish in real time, and give early warning through the gradient change of the thermal image and the temperature trend.

  • Defect temperature detection of hot blast stove body
Thermal-imager

If the shell and vault of the hot blast stove work for a long time, the surface refractory material will thin and fall off. If it is not found in time, it will seriously affect the stable operation of the entire process.
