The utility model discloses a thermal shock resistant and erosion resistant ladle long nozzle. Refractory material field, the long nozzle comprises a long nozzle body, a hollow steel flowing channel is formed in the long nozzle body, an inverted-cone-shaped bowl opening is formed in the top of the steel flowing channel, and the long nozzle is characterized in that two layers of linings are arranged on the inner side wall of the long nozzle body and comprise the anti-erosion lining and the thermal shock resistance lining, and the outer side of the anti-erosion lining is wrapped with the thermalshock resistance lining. By means of the mode, the baking-free long nozzle can solve the problem that an existing baking-free long nozzle is poor in thermal shock resistance and erosion resistance. 本实用新型公开了一种抗热震耐侵蚀钢包长水口，属于耐火材料领域，其包括长水口本体，在所述长水口本体内开设有中空的流钢通道，所述流钢通道的顶部设置有倒锥形的碗口，其特征在于，在所述长水口本体的内侧壁设置有两层内衬：抗侵蚀内衬和抗热震内衬，所述抗热震内衬包覆于抗侵蚀内衬的外侧。通过上述方式，本实用新型能够解决现有免烘烤长水口抗热震、耐侵蚀性能差的问题。
