Description

Apparatus for removing foreign materials from surface of skin pass mill}

The present invention relates to an apparatus for removing foreign substances, and more particularly, to an apparatus for removing foreign substances on the surface of a skin pass mill for easily removing foreign matters and the like deposited on the surface of a skin pass mill in a skin pass rolling process.

In general, the skin pass rolling process is a final process of the hot rolled coil produced in the hot rolled rolling process, and is a very important process for improving the quality of the product by improving the flatness and shape of the hot rolled coil.

However, the surface of the skin pass mill of such a skin pass rolling process may cause foreign matters such as cooling water or scale, dust, or oil due to the nature of the manufacturing process, and such foreign matters may leave a mark on the surface of the hot rolled coil. As a result, a fatal defect is generated which degrades the quality of the hot rolled coil as a product.

In addition, when the rolling process is performed for a long time with foreign matter on the surface, the surface of the skin pass mill may be damaged.

Therefore, in order to remove foreign substances on the surface of the skin pass mill, the rolling process is stopped and the operator manually cleans the surface of the skin pass mill by using a cleaning tool. Interruption of the process has led to major problems of reduced utilization and productivity.

In order to solve the problem as described above, as shown in Figure 1, the knife 10 fixed by the support 11 to the surface of the skin pass mill (B) is in close contact, the surface of the skin pass mill (B) The foreign matter buried in is used by the method by which the knife 10 is removed. However, such a conventional method can be easily removed by the scale 10 or the solidified scale or dust, when the foreign matter is adsorbed on the surface of the skin pass mill (B) together with the scale or dust oil. A problem arises that the skin pass mill B is not completely removed from the skin pass mill B. In addition, a severe friction occurs between the skin pass mill B and the knife 10, so that the surface of the skin pass mill B is applied to the knife 10. There was a problem that the skin pass mill (B) must be replaced.

On the other hand, Figure 2 shows another foreign matter removal device on the surface of a conventional skin pass mill. Asbestos nonwoven fabric 20 fixed by the support 11 as shown in Figure 2 is in close contact with the surface of the skin pass mill (B), foreign matter asbestos non-woven fabric 20 buried on the surface of the skin pass mill (B) It is removed by).

However, in this manner, foreign matter adsorbed on the surface of the skin pass mill B can be easily removed, but in this manner, the skin passes through the friction between the skin pass mill B and the asbestos nonwoven fabric 20 and thus the skin pass. The surface of the mill (B) was damaged and had to be replaced. In addition, asbestos powder or foreign matter generated by the friction between the skin pass mill B and the asbestos nonwoven fabric 20 falls to the surface of the skin pass mill B or the driving roll C, thereby again passing the skin pass mill B. Along with the problem of contaminating the surface of the), asbestos powder was harmful to the human body.

Accordingly, an object of the present invention is to remove foreign substances from the surface of the skin pass mill, and at the same time to suck in the foreign substances removed from the surface of the skin pass mill, so that the surface of the skin pass mill can be kept clean at all times. To provide.
