Method and device for removing burrs at bottom of bent casting blank on continuous casting machine

The invention discloses a method and device for removing burrs at the bottom of a bent casting blank on a continuous casting machine. The device comprises casting blank bending situation detecting systems arranged on the two sides of the end of a roller bed set, and deburring systems arranged at the ends of roller beds. According to the method, when the head of the bent casting blank is moved to be near installing plates, when a slab starts to shield a first phototube, the farthest phototube, capable of being shielded by the head of the bent casting blank, below a reference face within 5s is recorded and determined to be numbered as -n1, and accordingly the maximum value Bmax of the head bending of the bent casting blank is calculated; and according to the maximum value Bmax of the head bending of the bent casting blank, the deburring roller oil cylinder rising height head H is adjusted, accordingly, deburring rollers start to deburr the head of the bent casting blank, and in a similar way, the deburring rollers start to deburr the tail of the bent casting block so that the removing process of the burrs at the bottom of the whole bent casting blank 1 can be finished. The device is simple in structure, ingenious in design, convenient to mount and demount and low in cost.
