A protective coating applied to the interior of a tundish for resisting high-temperature molten steel erosion
By preparing a protective coating of alumina substrate and materials such as magnesium oxide and chromium oxide on the inner surface of the tundish, the problem of high-temperature corrosion of the tundish was solved, and the molten steel was effectively blocked at high temperatures, thus improving the safety and continuity of the tundish.

Abstract
The application discloses a protective coating applied to high-temperature steel liquid erosion inside a tundish, and the preparation raw material components of the protective coating are as follows in terms of weight parts: 80-150 parts of large-particle alumina, 20-80 parts of small-particle alumina, 100-200 parts of white corundum, 20-80 parts of magnesium oxide, 5-15 parts of chromium oxide, 20-70 parts of a binder, 10-20 parts of cellulose, 2-5 parts of mineral fiber and 150-250 parts of water. The coating has the advantages of high-temperature resistance, low thermal expansion coefficient and thermal shock resistance, is suitable for long-term work in a high-temperature environment, and can temporarily block high-temperature steel liquid, thereby providing effective time for worker safety evacuation.
