Reasons for the destruction of ladle purging plug

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.

Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc.
