Description

Stainless Steel Surface Polishing Equipment {DEVICE FOR FINISHING SURFACE OF STEINLESS}

The present invention relates to a stainless steel plate surface gloss treatment apparatus, and more particularly to a stainless steel plate surface gloss treatment apparatus that can polish the surface by a continuous process without cutting the stainless steel plate.

In general, stainless steel sheets produced in a steel mill through a rolling process are not directly applied to a product, but undergo various post-treatment processes separately to improve commercial properties. One of such post-treatment processes is a surface gloss treatment process, and in the case of stainless steel, it is a universal post-treatment process so that almost all products are polished.

In FIG. 1, the polishing process of such a stainless steel sheet (hereinafter referred to as steel sheet) is schematically shown.

In general, a steel sheet received in the form of a coil includes a decoil process (A) for drawing coils, a cutting process (B) for cutting a coil to be cut to a predetermined size into a sheet form, and the cutting process (B). A polishing process (C) for polishing by polishing the surface of the finished sheet, a washing process (D) for washing the polishing agent added during the polishing process (C), a drying process (E), and handling In order to prevent surface damage of the steel sheet is shipped as a finished product through a series of processes including a taping process (F) for taping the surface.

As shown in FIG. 2, the general polishing apparatus employed in the polishing process (C) during the above process includes a horizontal table (1) on which the steel plate (2) can be placed, and a rotating shaft of the motor (M). And a plurality of rotors 3 connected and rotatably installed on the horizontal table 1, and an abrasive 5 attached to the bottom of the rotors 3.

Therefore, when the rotating body 3 rotates at a high speed by turning on the motor M, the abrasive 5 attached to the bottom of the rotating body 3 and the horizontal table 1 below the abrasive 5 are formed. The surfaces of the steel sheets 2 fixed above are rubbed with each other, and the surfaces of the steel sheets 2 are polished while being polished. At this time, the rotating body (2) is arranged in a plurality in a row can move forward and backward of the horizontal table (1), the surface of the steel sheet (2) can be uniformly polished.

On the other hand, in the gloss treatment apparatus, a two-step process is performed in order to gloss the surface of the steel sheet (2).

The first step is a surface polishing process in which an abrasive 5 having a relatively high hardness is attached to the rotating body 3. In this step, the foreign matter adhering to the surface of the steel sheet 2 is removed and the smoothness of the steel sheet 2 is increased.

The steel plate 2 subjected to the surface polishing process is subjected to the second step process, which is processed by a predetermined polish agent administered to the surface of the steel sheet 2 through a conduit formed inside the rotor 3. The second step is a surface gloss process. As the abrasive 5 employed at this time, a soft material which is easy to polish is used, for example, melt or wool.

However, the above gloss treatment apparatus has the following problems.

In the polishing apparatus, the steel sheet 2 should be fixed on the horizontal table 1 so that the rotating body 3 can easily polish the surface of the steel sheet 2, so that the steel sheet 2, which is put into a roll, is difficult to work with. . Therefore, the process is complicated because the cutting process (B) for cutting the steel sheet 2 into a sheet form must be accompanied by cutting to a certain size.

In addition, the gloss treatment apparatus is capable of processing only the steel sheet (2) cut in the form of a sheet, each step is not performed in a continuous process, each steel sheet for each process from the cutting process (B) to the taping process (F) There is a hassle to move it. In particular, the steel sheet after the first stage surface polishing process must be moved to another table for the second stage surface polishing process, or to replace the abrasive 5 of the rotating body 3. Therefore, the working speed is low, and mass production is difficult.

The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a stainless steel surface surface gloss treatment apparatus that can polish the surface by a continuous process without cutting the stainless steel sheet.
