Background

As an important container for transporting molten steel and performing secondary metallurgical reactions in converter and continuous casting sections, the management and dispatch of the ladle plays an important role in optimizing the operation and energy saving and consumption reduction of steel plants. The ladle is composed of barrel, lining, nozzle opening and closing device and air-permeable bricks. The main function of the ladle is to receive the molten steel and part of the slag flowing out of the tapping door of the primary steelmaking furnace (converter or electric furnace). The ladle can calm the molten steel for a period of time to adjust the temperature of the molten steel, make the composition uniform and make the non-metallic inclusions in the molten steel float. At the same time, the steel flow is opened and closed during the pouring process to control the flow of molten steel and ensure smooth pouring.

In recent years, major accidents in the metallurgical industry have frequently occurred due to safety hazards such as overheated molten steel (iron) breaking through the ladle, severe wear of the ladle lining, and fatigue damage during the iron and steel making process, posing a serious threat to production safety.

Practice has shown that the initial defects of the ladle lining will gradually develop from point to surface until complete failure. When the lining is peeling off in the early stage, the temperature of the peeling point area will be abnormally high, and the temperature of the defective area will be significantly higher than that of other locations.

Therefore, using infrared thermal imagers to achieve rapid online detection and diagnosis can timely detect abnormal temperature changes in equipment, locate defective parts, avoid safety accidents in time, and ensure normal production operations.
