Narrow face copper plate of crystallizer with curved structure

The utility model relates to the field of continuous casting of metals, in particular to a narrow face copper plate of a crystallizer with a curved structure. The narrow face copper plate comprises a plane area (2) and a curved area (3), wherein circular tube type cooling water channels (6) and/or rectangular cooling water channels (7) are uniformly distributed in the copper plate; the thickness of the edge and corner of the narrow face copper plate (1) is the maximum and more 10mm to 100mm than the thickness of the plane area (2) in the middle; and the curved area (3) and the plane area (2) are smoothly connected in a tangential way. The narrow face of the casting slab of the copper plate is raised outwards, so as to be beneficial to avoiding the cracking occurrence at the edge and corner of the casting billet to improve the surface quality of the hot-rolled sheet steel, and contribute to the prolonging of the service life of the copper plate.
