There are four main reasons for the damage of ladle purging plug: thermal stress, mechanical wear, mechanical stress and chemical attack.
1. Thermal stress
Purging plug are subjected to strong thermal shock, causing peeling of the working surface.
2. Mechanical wear
3. Mechanical stress
Due to the different expansion coefficients of the refractory material, the ladle permeable brick is subjected to mechanical stress, causing transverse cracks or even fractures.
4. Chemical attack
The physical erosion caused by molten steel, and the chemical corrosion caused by the continuous penetration of the steel slag and molten steel are the main reasons for the damage of the ladle purging plug.
