Detail

In the production process of making steel pipes on the high frequency welded pipe machine production line, three links of raw materials, welding technology and roll adjustment should be focused on control.

 

Secondly, the high frequency welded pipe machine must control the high-frequency welding

In the process of high-frequency welding of steel pipes with high frequency welded pipe machine, the control of welding process and process parameters, the placement of induction coils and resistors, etc. have a great influence on the welding quality of steel pipe welds.

 

High frequency welded pipe machine

 

1. Control of steel pipe weld gap

After the steel strip is formed by a high frequency welded pipe machine and the guide roller is oriented, a round steel tube blank with an open gap is formed. The squeeze amount of the squeeze roller is adjusted to control the weld gap between 1 and 3 mm. Keep the weld ends flush. If the weld gap is controlled too large, the weld will be poorly welded and cause unfusion or cracking; if the weld gap is controlled too small, excessive heat will cause the weld to burn, molten metal splashes, and affect the welding quality of the weld. .

 

2. Adjustment of the position of the high-frequency induction coil

The induction ring should be placed on the same center line as the steel pipe. The distance between the front end of the induction ring and the center line of the squeeze roller should be as close as possible depending on the specifications of the steel pipe without burning the squeeze roller. If the induction coil is far away from the squeeze roller, the effective heating time is longer and the heat-affected zone is wide, so that the strength of the steel pipe weld is reduced or the weld is not penetrated; on the contrary, the induction coil is easy to burn the squeeze roller.

3. Regulation of the position of the resistor

Resistor is one or a group of special magnetic rods for welded pipes. The cross-sectional area of the resistor should usually not be less than 70% of the cross-sectional area of the inner diameter of the steel pipe. Its function is to make the induction coil, the edge of the pipe blank weld and the magnetic rod form an electromagnetic induction loop. The proximity effect is produced, and the eddy current heat is concentrated near the edge of the weld of the tube blank, so that the edge of the tube blank is heated to the welding temperature. The impedance device should be placed in the heating section of the V-shaped zone, and the front end should be at the center of the squeeze roller so that its center line is consistent with the center line of the tube. If the impedance device is not placed properly, it will affect the welding speed and welding quality of the welded pipe, and cause the steel pipe to crack.

 

4. High-frequency welding process parameters-control of input heat

When the high-frequency input heat is insufficient and the welding speed is too fast, the edge of the heated pipe body cannot reach the welding temperature, and the steel still maintains its solid structure and cannot be welded, forming cracks that are not fused or welded; When the high-frequency input heat is too large and the welding speed is too slow, the edge of the heated pipe body will exceed the welding temperature, which is prone to overheating or even burning, causing the weld to break down, causing metal splash and forming shrinkage holes.

 

High frequency welded pipe machine

 

We can control the amount of high-frequency input heat by adjusting the high-frequency welding current (voltage) or adjusting the welding speed, so that the weld seam of the steel pipe needs to be penetrated and not penetrated, and a steel pipe with excellent welding quality can be obtained.

 

The three important links of raw material, welding and roll adjustment in the production process of welded steel pipes are carried out on the high frequency welded pipe machine. If strict control is implemented, the quality of welded pipes will be effectively improved.

Time of issue : 2024-12-03
Bedroom screw looping (generally used in the field of metal working, such as steel rolling) is a device used for specific processing operations. Used roller bedroom spiral looper can still work effectively after proper maintenance and debugging. Its operation mainly includes the following aspects:

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.
