Device for testing shot ball project pattern in descaler
[16] The present invention relates to a descaler facility for stripping scales of strips, and more particularly, to a shortball projection pattern inspection device for inspecting a projection pattern of a shotball shot onto a strip in a descaler facility.
[17] In general, during the production of stainless steel hot rolled coil, the strip passed through the dequenching facility after the continuous annealing operation passes through the descaler facility for peeling the scale layer formed on the strip surface.
[18] The descaler facility is a device for projecting a small metal ball (hereinafter referred to as a shot ball) onto a strip surface by peeling a scale layer through a high-speed rotating wheel, and the shot pattern of the shot ball is very important for efficient scale layer peeling of the device. .
[19] However, since the descaler facility is generally made inside the sealed facility to prevent the diffusion of dust and the like generated when the scale is removed, the pattern of shotball shot on the strip cannot be confirmed.
[20] Therefore, in order to check the projection pattern, conventionally, the equipment is stopped and the operator attaches the cardboard onto the strip with the fixed tape, and then attaches the shotball for about 3-5 seconds and pulls out the cardboard again to check the remaining traces on the cardboard. The projection pattern was examined.
[21] However, the conventional structure is difficult to attach cardboard to the lower surface of the strip, as well as the operator has to work inside the descaler facility filled with dust and noise, there is a very poor working environment.
[22] In addition, corrugated cardboard is easily broken during shot projection, and it is difficult to inspect the actual projection pattern, and it is very difficult to adjust the projection angle based on the result, which is a factor of deterioration of product quality and reproduction line.
[23] Accordingly, the present invention has been made in order to solve the above problems, the shot projection of the descaler facility that the operator can check the projection pattern is mechanically introduced into the descaler facility, without entering the descaler facility. The purpose is to provide a pattern inspection apparatus.
