The utility model relates to the technical field of rolling mills, and discloses a three-roller rolling mill with a radial locking structure for round steel processing, which comprises a rack and a rolling mill main body, the rolling mill main body is arranged inside the rack, an opening is arranged at the middle position inside the rolling mill main body, and a mounting seat is fixed at the top of the front end of the rolling mill main body. When the three-roller rolling mill with the radial locking structure for round steel machining is used for rolling a round steel piece, after the round steel piece is guided out from the interior of an opening, a first servo motor can be controlled to start to drive a bidirectional lead screw to rotate, and the first servo motor rotates and can drive two sets of side bases to move inwards through a threaded sleeve in threaded connection at the same time; the locking device is simple in structure and can abut against the two sides of the round steel piece respectively, auxiliary locking and positioning are carried out on the round steel piece at the rolling outlet of the rolling mill, deformation of the round steel piece is reduced, and the problem that auxiliary radial locking and positioning are inconvenient to carry out on the round steel piece is solved.
