Working Lining（coating）
Easy Application
Simple trowel or spray application minimizes downtime, improves maintenance efficiency, and enables quick turnaround between heats.
Low Contamination
Formulated with high-purity materials to minimize interaction with molten steel and ensure superior steel cleanliness.
Strong Corrosion Resistance & Durability
Effectively resists erosion from molten steel and slag, extending service life and reducing overall refractory consumption.
