The invention provides a tundish ramming material. The tundish ramming material is prepared from the following raw materials in parts by weight: 30-50 parts of serpentine, 12-20 parts of phosphate ores, 35-43 parts of magnesia, 13-19 parts of alumina, 7-12 parts of magnesium sulfate, 3-7 parts of a binder, 2-5 parts of an antioxidant, 10-15 parts of graphite tailings, 2-6 parts of carbon black, 7-13 parts of vanadium soil and 10-16 parts of glass fibers. The tundish ramming material has the advantages of low energy consumption and low cost, the service life of the tundish ramming material canbe prolonged to 20 h or above, the use efficiency of magnesia resources is effectively improved, the magnesia resources are saved, cheap serpentine and phosphate ores are used, the cost is reduced, energy is saved, and the environment is protected.
本发明提出了一种中间包捣打料，由以下原料按重量份制备而成：蛇纹石30‑50份、磷矿石12‑20份、镁砂35‑43份、氧化铝13‑19份、硫酸镁7‑12份、粘结剂3‑7份、抗氧剂2‑5份、石墨尾矿10‑15份、炭黑2‑6份、钒土7‑13份和玻璃纤维10‑16份。本发明中间包捣打料具有低能耗、低成本的优势，在中间包捣打料使用寿命可提高到20h以上，不仅有效的提高了镁砂资源的使用效率，节约了的镁砂资源，而且配合使用了价格低廉的蛇纹石、磷矿石，成功实现了降本节能，保护环境。
