The present invention relates to an intermediate blank connection system for hot-rolled strip headless rolling and a connection method, and belongs to the technical field of intermediate blank connection for strip steel headless rolling. The connection system and the connection method realize matching of an intermediate blank connection device and speed of a unit through a translation drive system. A mounting frame is used to provide support for cutting devices, and the cutting devices are divided into two groups arranged in the mounting frame to achieve clamping of a front slab and a rear slab respectively. Interlaced dovetail cutting edge structures are used to achieve cutting and ensure a good longitudinal stress state. Finally, a certain difference is set in sizes of width directions between cutting edges, to ensure that there is certain extrusion deformation in a process of forming dovetail cutting groove connection, and enhance a connection effect. At the same time of realizing a good intermediate blank connection effect finally, a structure of the connection device is greatly simplified, and investment and operating cost is reduced.
