Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.
[0027] See Figure 2-Figure 8 , a device for cutting billet defects and flashes, comprising a U-shaped frame 4, fasteners 5, hangers 6, a motor 10, and a wire brush 11, the U-shaped frame 4 is a U-shaped frame, and the opening is passed through the buckle Part 5 is closed, and U-shaped frame 4 is used for containing square billet 1, and several hangers 6 are fixed outside U-shaped frame 4, and wire brush 11 is fixedly connected with the output shaft of motor 10, and motor 10 drives wire brush 11 to rotate. Hanger 6 is fixed on U-shaped frame 4 top and top opening, and the bottom of U-shaped frame 4, guarantees that crane applies force evenly, and guarantees that turning over is stable.
[0028] See Figure 6-Figure 8 The device for cutting bill...

The invention relates to a device and a method for cutting square billet defects and flashes. The device comprises a U-shaped frame, fasteners, hangers, a motor and a wire brush, wherein the U-shaped frame is a U-shaped frame; an opening of the U-shaped frame is closed through the fasteners; the U-shaped frame is used for containing square billets; the hangers are fixed outside the U-shaped frame; the wire brush is fixedly connected to an output shaft of the motor; and the motor drives the wire brush to rotate. The device and the method have the advantages that the flashes on the square billets longitudinally cut from plate blanks can be effectively removed, so that the blockage of the flues caused by the falling of the cutting knobs during heating and the surface scabs and folding of the cutting knobs on the products are effectively reduced, or the steel piling accidents caused by the blockage of the cutting knobs on the guide and guard of a rolling mill are reduced.
Description
technical field [0001] The invention relates to a device and method for cutting billet defects and burrs. Background technique [0002] At present, the cutting of continuous casting slabs mostly adopts the flame method, see figure 1 , During the cutting process, the cutting slag will form a certain amount of flash, which is also called cutting nodules. If these flashes are not removed, they will be brought into the heating furnace. Some flashes will fall off in the heating furnace, and some will not fall off. It is also easy to block the flue, and the ones that will not fall off enter the dephosphorization machine with the billet. Of course, most of them will be removed, but there are also a small part that are not removed. It will form scars on the surface of the product, and in serious cases, it will lead to rejection, or the cutting tumor will block the guide of the rolling mill and cause a steel pile accident. Therefore, the flash of the cutting billet must be removed b...
