Then, the surface of the cleaned flat ingots is rinsed through the rinsing water pipe 19. By transporting the flat ingots through the roller conveyor 2, scum is removed during the transport process, achieving continuous operation and improving efficiency.

[0031] Multiple sets of rinsing water pipes 19 can be arranged to achieve multiple rinsing operations. The rinsing water pipe 19 at the forefront can also rinse the area cleaned by the brush cylinder 7, achieving a wet brushing effect. This slag cleaning device for flat ingot casting can effectively remove most of the oxide layer and loose impurities from the surface of the flat ingot.

[0032] In this embodiment, vertical plates 6 are provided at both ends of the movable frame 5, and a central shaft 24 capable of driving rotation is provided between the two vertical plates 6. Multiple brush cylinders 7 are spaced apart on the central shaft 24. Multiple roller grooves 20 corresponding to each brush cylinder 7 are provided on the roller shaft 18 of the roller conveyor 2. First pulleys 23 are sleeved on the central shaft 24 between adjacent brush cylinders 7. A dual-axis motor 9 is mounted on the movable frame 5. Second pulleys 10 are sleeved on the shafts at both ends of the dual-axis motor 9. A belt 11 is sleeved between the first pulleys 23. During operation, the dual-axis motor 9 drives the second pulleys 10 to rotate, which in turn drives the first pulleys 23 to rotate via the belt 11, thereby rotating the central shaft 24 and further causing the brush cylinders 7 to rotate.

[0033] By setting multiple roller grooves 20, each roller groove 20 can transport one flat ingot, and adjacent flat ingots do not affect each other and will not collide.

A cover plate 16 is provided on the support block 15, and the bottom surface of the cover plate 16 is provided with an upper semicircular groove corresponding to the lower semicircular groove. Both ends of the cover plate 16 are detachably mounted to the support block 15 using screws 17. Multiple positioning grooves 26 are provided around the circumference of the flushing water pipe 19. Each pair of symmetrical support blocks 15 forms a group, and multiple groups of support blocks 15 can be set, thereby allowing for multiple flushing water pipes 19. The flushing direction of the flushing water pipes 19 can be adjusted by the cooperation of the positioning protrusions 25 and the positioning grooves 26. For example, by rotating the flushing water pipe 19 and inserting different positioning grooves 26 into the positioning protrusions 25, the flushing direction can be adjusted. Then, the cover plate 16 is fixed to the support block 15 with screws 17, and the flushing water pipe 19 is fixed by the cooperation of the lower semicircular groove and the upper semicircular groove.
