The invention provides a tundish coating. The tundish coating is prepared from the following raw materials in parts by weight: 80-100 parts of medium-grade sintered magnesia, 7-12 parts of slaked lime, 15-25 parts of glass fibers, 10-20 parts of aluminum powder, 5-12 parts of melamine, 3-10 parts of rosin, 10-15 parts of magnesium sulfate, 20-30 parts of hollow ceramic micro beads and 14-18 partsof aluminum chloride. The raw materials are wide in source, and the obtained tundish coating is long in service life, has a heat preservation performance and corrosion resistance, can further purify molten steel, and is good in low-temperature cohesiveness, high in adhesive force, good in effect and wide in application potential.
本发明提出了一种中间包涂料，由以下原料按重量份制备而成：中档烧结镁砂80‑100份、熟石灰7‑12份、玻璃纤维15‑25份、金属铝粉10‑20份、三聚氰胺5‑12份、松香3‑10份、硫酸镁10‑15份、空心陶瓷微珠20‑30份和氯化铝14‑18份。本发明原料来源广，得到的中间包涂料使用寿命长，具有保温性能和耐侵蚀性，能进一步纯化钢液，低温粘结性好，附着力高，具有良好的效果，有广阔应用的潜力。
