1. Thermal Shock Resistance

Refractories with high thermal shock resistance are critical. A study indicates that over 60% of ladle failures are due to thermal shock. Choosing materials that can withstand rapid temperature changes helps enhance durability.

2. Erosion Resistance

The ladle environment can be chemically aggressive. For instance, the presence of slag can lead to significant erosion. Utilizing high-quality refractory products can reduce erosion rates by 40%, thereby increasing the lifespan of the lining.

Common Ladle Lining Materials
