The invention relates to a continuous casting tundish split type eccentric brick cup, which comprises an upper brick cup and an eccentric lower brick cup arranged at the bottom of the upper brick cup, wherein an upper through hole is formed in the upper brick cup in a penetrating way, a lower through hole is formed in the eccentric lower brick cup in the penetrating way, the upper through hole and the lower through hole are oppositely formed in the penetrating way for forming a brick cup center hole, and the bottom outer edge of the eccentric brick cup is provided with two mutually vertical grooves. The continuous casting tundish split type eccentric brick cup solves the problem of nozzle centering deviation in a crystallizer when a continuous casting machine is used for simultaneously casting end surfaces in various specifications, and the casting blank quality is improved. Meanwhile, the continuous casting tundish split type eccentric brick cup has the advantages that the structure is simple, the operation is convenient, the use safety is high, and the like; under the condition of no position modification on a tundish case and a brick cup hole, the problem of centering deviation of a nozzle in the crystallizer during multi-section casting is solved.
