Abstract
The invention discloses a polishing method for a hot-rolled stainless steel welded pipe weld joint. The polishing method includes the step that four polishing procedures are carried out on the weld joint in the weld joint advancing direction through polishing wheels with the gradually-increased sand grain densities of the polishing faces, wherein an included angle of 10 degrees to 15 degrees is formed between the polishing wheel used in the fourth polishing procedure in the weld joint advancing direction and the weld joint advancing direction. By means of the polishing method for the hot-rolled stainless steel welded pipe weld joint, the 600-degree finish-degree requirement can be met after follow-up surface polishing line treatment, and the finish degree of the surface of a stainless steel welded pipe is greatly increased.
Description
Technical field
The present invention relates to a kind of polishing process, particularly relate to a kind of hot-rolled stainless steel welded pipe weld grinding method.
Background technology
The difficult point of stainless steel welding tube surface finish, just in the process to soldered, is difficult to the requirement reaching best bright finish, and therefore, the surface smoothness of traditional stainless steel welding tube is not very high.Along with a large amount of uses of decoration tubing, require more and more higher to the outer surface of stainless steel welding tube, be therefore necessary to invent a kind of hot-rolled stainless steel welded pipe weld grinding method.
Summary of the invention
The object of this invention is to provide a kind of hot-rolled stainless steel welded pipe weld grinding method, stainless steel welding tube can be made can to reach the smoothness requirements of 600 degree after by follow-up surface finish line process, substantially increase the fineness of stainless steel welded tube-surface.
For achieving the above object, the invention provides a kind of hot-rolled stainless steel welded pipe weld grinding method, this polishing process is the polishing that the grinding wheel butt welded seam adopting the grains of sand density of buffed surface to improve gradually in weld seam direction of advance carries out four procedures, and the grinding wheel used in the 4th road polishing operation in weld seam direction of advance and weld seam direction of advance are 10-15 degree angle.
As a further improvement on the present invention, the grinding wheel used in first three road polishing operation in weld seam direction of advance and weld seam direction of advance are 45 degree of angles, and the grinding wheel used in described first three road polishing operation is alternately distributed with different beat direction from the 45 degree of angles formed between weld seam direction of advance.
Further improve as of the present invention, the grinding wheel that described first three road polishing operation uses is followed successively by No. 100 grinding wheels, No. 100 grinding wheels and No. 180 grinding wheels, and the grinding wheel that the 4th road polishing operation uses is No. 320 grinding wheels.
Compared with prior art, the beneficial effect of hot-rolled stainless steel welded pipe weld grinding method of the present invention is as follows:
(1) the 4th procedure employing and weld seam direction of advance are the grinding wheel of 10-15 degree angle, and the grains of sand density of the buffed surface of grinding wheel in four procedures improves gradually in weld seam direction of advance, make the stainless steel welding tube after processing after by follow-up surface finish line process, 600 degree of surface smoothnesses can be reached, substantially increase the fineness of stainless steel welded tube-surface.
(2) grinding wheel in 45 degree of angles is alternately distributed with different beat direction, and adopts the grinding wheel of No. 100, No. 100, No. 180, No. 320, can ensure the surface smoothness in follow-up polishing process further.
By following description also by reference to the accompanying drawings, the present invention will become more clear, and these accompanying drawings are for explaining embodiments of the invention.
Accompanying drawing explanation
Fig. 1 is hot-rolled stainless steel welded pipe weld grinding schematic diagram.
Detailed description of the invention
With reference now to accompanying drawing, describe embodiments of the invention, element numbers similar in accompanying drawing represents similar element.
Please refer to Fig. 1, described hot-rolled stainless steel welded pipe weld grinding method is the polishing that the grinding wheel b butt welded seam adopting the grains of sand density of buffed surface to improve gradually in weld seam a direction of advance carries out four procedures, the grinding wheel b used in first three road polishing operation in weld seam a direction of advance and weld seam direction of advance are 45 degree of angles, and the grinding wheel b used in the 4th road polishing operation and weld seam a direction of advance are 10-15 degree angle.The grinding wheel b used in described first three road polishing operation is alternatively distributed with different beat direction from the 45 degree of angles formed between weld seam a direction of advance.The grinding wheel b that described first three road polishing operation uses is followed successively by No. 100 grinding wheels, No. 100 grinding wheels and No. 180 grinding wheels, and the grinding wheel b that the 4th road polishing operation uses is No. 320 grinding wheels.Adopting aforementioned is stainless steel welding tube after the grinding wheel b of 45 degree and 10-15 degree angle processes, after by follow-up surface finish line process, can reach 600 degree of surface smoothnesses, substantially increase the fineness of stainless steel welded tube-surface.
More than in conjunction with most preferred embodiment, invention has been described, but the present invention is not limited to the embodiment of above announcement, and should contain various carry out according to essence of the present invention amendment, equivalent combinations.
