The embodiment of the invention provides a cutting device and a cutting method for a zone-melting silicon rod. The zone-melting silicon rod cutting device comprises a supporting frame, a rotary fixing mechanism and a cutting mechanism. The rotary fixing mechanism comprises a fixing sleeve assembly and a driving supporting assembly, and the fixing sleeve assembly is rotatably arranged on the supporting frame through the driving supporting assembly; the cutting mechanism is movably arranged between a cutting position and a neutral gear position in the first preset direction. Therefore, the cutting device for the zone-melting silicon rod has the advantages that the technical problem of bursting caused by stress concentration in the cutting process is solved, the yield of finished products during cutting of the zone-melting silicon rod is increased, and the cutting cost is reduced. 本发明的实施例提出一种区熔硅棒的切割装置和切割方法。其中，本发明的实施例的区熔硅棒的切割装置包括支撑架、旋转固定机构和切割机构。所述旋转固定机构包括固定套筒组件和驱动支撑组件，所述固定套筒组件通过所述驱动支撑组件可转动地设置在所述支撑架上；所述切割机构沿第一预设方向
