Working Lining（Dry Mass）
Easy Installation
Dry forming method allows for quick and convenient construction with a smooth and dense surface.
Temperature Control
Maintains stable molten steel temperature, minimizes heat loss, and supports multi-furnace continuous casting operations.
Facilitates Slag Removal
Ensures easy removal of residual slag, improving tundish turnaround efficiency and reducing maintenance time.
Strong Slag Resistance
Effectively minimizes molten steel contamination from working lining materials, ensuring clean steel production.
