The slag line material comprises the following components in percentage by weight: more than or equal to 85% of stable zirconium oxide and monoclinic zirconium oxide, 0.5-3.0% of nano carbon black, 3-9% of crystalline flake graphite and 2-7% of phenolic resin, and the monoclinic zirconium oxide is more than 0 and less than or equal to 5%. On the premise of ensuring that the submerged nozzle slag line has high thermal shock resistance, the erosion resistance of the slag line is further improved, the number of continuous casting furnaces is increased, the cost of a continuous casting procedure is reduced, the quality of a casting blank is improved, the erosion resistance of the inner hole body is improved by improving the material of the inner hole body, and the service life of the inner hole body is prolonged. Slag line perforation possibly caused when the number of casting furnaces is high is avoided, and therefore the use safety of the submersed nozzle is greatly improved.
一种连铸浸入式水口渣线及浸入式水口，所述渣线材料的成分重量百分比为：稳定氧化锆+单斜氧化锆≥85％，纳米炭黑0.5～3.0％，鳞片石墨3～9％，酚醛树脂2～7％，并同时保证：0＜单斜氧化锆≤5％。本发明保证浸入式水口渣线在具有较高抗热震性的前提下，使渣线的抗侵蚀性得到进一步提高，提高了连浇炉数，不仅降低了连铸工序的成本，而且有利于改善铸坯质量，且，通过改进内孔体材料提高内孔体的抗侵蚀性，避免高浇铸炉数时可能引起的渣线穿孔，从而使浸入式水口的使用安全性大大增强。
