The invention relates to an automatic protection device for steel billet roller ways. Incoming steel billets are conveyed to a weighing roller way through a conveying roller way, wherein a guide device is arranged between the weighing roller way and the conveying roller way adjacent to the weighing roller way, and a guide plate of the guide device is operated by a hydraulic cylinder to ascend and descend to control the ascending and the descending of the steel billets on the conveying roller way; a proximity switch for detecting whether the guide plate ascends and descends or not is arranged on the guide device; a cold metal sensor for tracking and detecting following steel billets is arranged in front of the guide device according to an incoming direction; the proximity switch, the cold metal sensor and the output end of a weigher are connected to a PLC (programmable logic controller) of a conventional roller way control system; one output end of the PLC is connected with a control circuit of the hydraulic cylinder. According to the device, the following moving steel billets are kept out of contact with the steel billet which is weighed, the number of the steel billets contacting with the roller ways and the contact areas of the steel billets and the roller ways are reduced, the magnitude of stress and the stress direction are eliminated, and equipment damage caused by collision between the steel billets is eliminated.
