[0028] Working principle: When in use, the staff transports the steel pipe into the cold rolling box 1 through the conveying component 9. When the steel pipe passes the bottom of the spray plate 6, the staff starts the nozzle 7 and starts to flush the outer wall of the steel pipe. The anti-rust liquid is used for flushing, which will not cause damage to the steel pipe. Then when the steel pipe enters the cleaning pipe 503, the staff starts the motor 501. The output end of the motor 501 drives the gear 502 to rotate, and the gear 502 drives the ring gear 504 to rotate. The ring gear 504 drives the cleaning pipe 503 to rotate between the two support plates 4, and then the cleaning pipe 503 drives the fixed cylinder 506 to rotate. The arc cleaning plate 510 fits with the outer wall of the steel pipe under the tension of the spring 507, and the arc cleaning plate 510 starts to clean the outer wall of the steel pipe.
