Through the causal analysis of industrial stainless steel 304 welded pipe waste, we understand that the roll adjustment process has played a very important role in the entire production process. That is to say, in the entire industrial stainless steel 304 welded pipe production process, if the roller is damaged or worn seriously, then it is necessary to replace some rollers on the unit in time, or a certain type of industrial stainless steel 304 welded pipe has been continuously produced in sufficient quantity The entire set of rolls needs to be replaced.

In the process of roll replacement, the rolls also need to be adjusted accordingly in order to obtain good stainless steel 304 welded pipe quality. Conversely, if the roll adjustment is not good, it is likely to cause defects such as twisting, lap welding, wavy edges, dents or scratches on the surface of the bulge and tube body, and even large ovality.

Next, the stainless steel welded pipe manufacturer will introduce the operation method of roll adjustment that should be mastered when changing rolls. First of all, we need to replace the specifications of DN150 industrial stainless steel 304 welded pipe. Generally, the entire set of rollers are replaced. The steps for roll adjustment are: first draw a center line with the steel wire from the inlet to the outlet of the unit, and adjust it so that the hole pattern of each frame is on a center line, and the forming bottom line meets the technical requirements.

After replacing the rolls as required, in order to ensure the welding quality of the industrial stainless steel 304 welded pipe, at the same time, it is necessary to perform a comprehensive adjustment of the forming roll, guide roll, squeeze roll, and sizing roll, and then focus on the closed hole of the forming roll , Guide roller, squeeze roller adjustment. The role of the guide roller is to control the direction of the weld seam of the stainless steel welded pipe and the height of the bottom line of the tube blank, ease the edge extension, control the rebound of the edge of the tube blank, and ensure that the tube seam is straight without twisting into the squeeze roller.

In short, during the welding process of industrial stainless steel 304 welded pipe, during the slow operation of the welding unit, the staff needs to pay close attention to the rotation of the rollers in various parts and adjust the rollers at any time to ensure that the welding quality and process size of the stainless steel 304 welded pipe comply with the regulations.
