Tundish Covering Compounds are specialized insulating materials applied to the surface of molten steel in tundishes during continuous casting operations. These compounds form a protective layer over the molten steel bath, helping to minimize heat loss, reduce atmospheric contamination, and maintain stable casting conditions throughout the casting sequence.
During continuous casting, molten steel remains exposed in the tundish for extended periods, making temperature control and oxidation prevention essential for maintaining steel quality. Tundish Covering Compounds create an insulating barrier that reduces thermal losses while limiting direct contact between molten steel and atmospheric oxygen. Depending on the casting requirements, these compounds may be insulating, partially sintering, or specially formulated to support steel cleanliness and process stability.
