Removing burrs on the billet has two functions: improving the quality of billet rolling; Reduce damage to conveyor and rolling rolls. After the slab is formed in the continuous casting machine, it is cut to a fixed length and then transported to the de roughening machine by the transmission roller conveyor.

Enter the cutting process of deburring village. The initial state of the deburring machine is that the plunger crossbeam of the deburring machine is in * * position, and the blade is retracted. The upper edge of the blade is located below the upper edge of the Han Dao. When the billet is transported to the grating LB1E

At this time, the walking speed of the billet decreases from the conveying speed Vt to the deburring speed Ve, and runs at Ve speed to the grating LB3. The billet

Transmission stopped.

The blade and plunger crossbeam rise simultaneously, and the blade presses against the lower surface of the billet. The billet moves to the right at a speed of Ve to complete the removal of burrs; When the billet reaches the grating LB2, both the blade and plunger crossbeam descend simultaneously, and the billet

The billet transfer stops, and the plunger crossbeam is flipped 90 ° to complete the cleaning procedure. Then the billet moves to the left at the conveying speed Vt,

Enter the program of removing burrs at the tail of the billet, and the process of removing burrs at the tail is the same as above.
