Detail
When the used ERW tube mills is used to make welded pipes, it is necessary to rely on the control of the squeeze roller to judge the quality of the welded pipe to be qualified. Therefore, the control of the squeeze roller is very important. There are many ways to control the squeeze roll, "two top rolls, two side vertical rolls and one bottom roll" is one of the squeeze roll methods.
The "two top rolls, two side vertical rolls and one bottom roll" five-roller extrusion method is mostly used for units above 325 of the used ERW tube mills. The two top rolls and the two side vertical rolls can be adjusted independently, and the two top rolls are effectively bonded to the steel. The belt edge can form a good extrusion force and effectively control the steel belt edge. This method is mostly used for centerline forming.
The disadvantage is that due to mechanical structural considerations and restrictions, the diameter of the upper two top rollers cannot be effectively reduced (when the size is below 325, it is usually equivalent to the diameter of the side vertical roller, when the size is greater than 325, the ratio is relatively appropriate). The bonding line with the steel belt is too long, and it is inevitable to bypass the high-frequency current through the upper top roller structurally.
The above-mentioned 4-roll type and 5-roll type will also have the problem similar to the “two on one side” mentioned in the previous article, and the problem will be more serious because the two upper rollers are coordinated up and down through the synchronization mechanism after the initial adjustment. The consistency of the adjustment or the unevenness of the edge caused by the forming of the steel belt edge needs to be overcome here, so the top roller of one side will be adjusted artificially to adapt to the forming defect of the steel belt edge to ensure the basic welding conditions . Therefore, whether the downward pressure given by the two upper rollers to the two sides is symmetrical, whether the center line is consistent with the side rollers, etc., will cause the aforementioned asymmetry in metallography. The pre-bending and forming defects of the part, the amount of pressure is different, which increases the probability of defects after welding. Therefore, the equipment processing accuracy or assembly accuracy of the production line equipment will directly lead to the high or low probability of welding defects. However, such welding defects cannot be found online, which will cause huge product waste.
Introduce you to 5 ways to adjust the squeeze roller of the used ERW tube mills. The specific method should be operated according to the actual situation. Please pay attention to safety and do not try it. If you need used welded pipe equipments, please contact us. You only need to inform us of your pipe-making needs, and our company will provide you with used welded pipe equipments that really suits your needs.

Apply of Bedroom screw looping
Time of issue : 2024-12-03
1.Basic construction: A typical roller type bedroom spiral hoop usually consists of two sets of rollers that form a spiral shaped channel for guiding and supporting the metal strip.
2.Operation principle: When the metal strip passes through the looper, the strip is guided and supported in the spiral path. Due to the spiral structure of the looper, the strip can be smoothly transmitted under the condition of uneven strip speed to ensure the normal progress of the subsequent process.
3.Commissioning and maintenance: Used equipment needs to be inspected and maintained in detail before use. Includes:
Cleaning: Remove oil, dust and so on from the surface.
Lubrication: Check and add lubricating oil to ensure the normal operation of each transmission component.
Calibration: Ensure that the neutralization pressure of the roller is set correctly.
Replacement parts: Check for wear and replace necessary parts.
4.Application process: In the process of use, it is necessary to pay attention to the operation specifications, monitor the operating status of the equipment, and adjust the equipment parameters in time to meet the strip specifications and process requirements. In addition, it is also necessary to pay attention to safe operation to prevent accidents.
Through the above methods, the used roller bedroom spiral looper can continue to play its function and provide support for metal processing production.
