The invention relates to an internal cooling type hot-charging roller table, and belongs to the technical field of hot rolling roller table equipment in the metallurgical industry. The technical solution is as follows: a water inlet pipe (4) stretches into a cavity (5) of a roller body (1) through a through hole (6) of a transmission shaft (3); a plurality of support disks (7) are arranged on thewater inlet pipe (4) in the cavity (5); a containing hole (72) matched with the water inlet pipe (4) is formed in the axis of each support disk (7); a plurality of rotating wheels(8) and rotating shafts (9) are arranged in the circumferential direction of the containing hole (72); the rotating shafts (9) are parallel to the axis of the support disk (7); the support disks (7) are rotatably connected to the water inlet pipe (4) through the plurality of rotating wheels(8) in the containing holes (72); and a plurality of water passing holes (71) are also formed in the circumferential direction ofeach support disk (7). The internal cooling type hot-charging roller table has the beneficial effects that the water inlet pipe can be prevented from sagging to interfere with the high-speed rotatingroller body and affect the normal operation of the roller table, and the circulation effect of cooling water is improved.
