The invention relates to the field of continuous casting function refractory materials and provides a ladle slag feather edge brick of a waste submersed nozzle slag line sludge material. The waste submersed nozzle slag line sludge material is mainly derived from a submersed nozzle used in a continuous casting workshop, a submersed nozzle slag line part mainly has the component of zirconium oxide,and the zirconium oxide used at the submersed nozzle is stabilized and has the advantages of being high in melting point, good in corrosion resistance, excellent in chemical stability, oxidation resistance and thermal shock stability, high in high temperature strength, very good in slag abrasion resistance, peeling resistance and molten steel impact resistance, and the like. Due to adoption of thewaste submersed nozzle slag line sludge material in the ladle slag feather edge brick, the slag abrasion resistance and the peeling resistance of the slag feather edge brick can be greatly improved,the service life of a ladle can be prolonged, the consumption of a ton steel refractory material can be reduced, pollution of the refectory material upon molten steel can be reduced, the wastes can beturned into wealth, the treatment expense of waste refractory materials can be reduced, and the environment pollution caused by the refectory materials and land occupation pressure can be reduced.
