Scraper and device, system and method for removing burrs of steel plate

The embodiment of the invention provides a scraper and a steel plate burr removing device, system and method, and relates to the technical field of special rolling factories. The scraper is used for removing burrs of a steel plate and comprises a supporting column and a sawtooth-shaped blade, and the supporting column is of a columnar structure. And the sawtooth-shaped blade is arranged on the outer peripheral surface of the supporting column. Therefore, the scraper comprises the sawtooth-shaped cutting edge, the cutting edge can easily lock steel plate burrs in irregular shapes, and the deburring effect is good; a certain angle is formed between the sawtooth-shaped blade and the surface of the steel plate, so that burrs are in point contact with the blade, the deburring resistance is greatly reduced, and the deburring rate is increased; the cutting edge is sawtooth-shaped, high in strength, good in toughness and resistant to impact. 本发明的实施例提供了一种刮刀以及去除钢板毛刺装置、系统和方法，涉及特轧厂技术领域。刮刀用于去除钢板的毛刺，刮刀包括支撑柱和锯齿形刀刃，支撑柱为柱状结构；
