The utility model relates to a novel strong push-guide device for centering the slab on the conveyor roller in hot continuous slabbing production in the metallurgical enterprise, comprising a push guide device, a transmission device, and a hydraulic drive unit. The utility model is characterized in that a plurality of vertical guide rollers are arranged on the pushing plate of the push-guide device, wherein, the vertical guide rollers are driven to rotate via a vertical guide roller driving hydraulic motor; an entrance guide beam is arranged at the front end of the push plate of the push guide; the synchronous gear shaft in the transmission device is arranged between two moving hydraulic cylinders of pushing plates; the cylinder head of the hydraulic mover is connected with the pushing plate of the push guide via a pushing rod of the lower pushing plate, a guide wheel of a guide rod, and a pushing rod of the upper pushing plate; the vertical guide roller is rolling-contacted with the slab; when in milling, the slab is held via the vertical guide rollers to align the unit center all the time. The utility model has the advantages of novel structure, safety and reliability, and rational control, and is a novel strong push-guide device integrated with economy and practicability.
