If the used high frequency tube mills refers to the chemical composition and mechanical properties of welded tube blanks that require certain inspection methods to be known as invisible defects; then, those defects that can be seen only by vision are called tube blanks. Overt defect.

 

The dominant defects of the welded tube blank of the used high frequency tube mills generally include cracked edges, broken edges, sawtooth, pitting, scratches, roll marks, dark spots, edge burrs, sickle bends, wrinkles, waves, edge warping, and points. Layers, warped skins, pinholes, sticky rolls, soft spots, rust, oxide layers, towers, loose rolls, etc. Let me introduce you to the causes of cracked edges and the impact of cracked edge billets on welded pipes.

Stratification

Layering refers to the phenomenon of two or more layers in the thickness direction of the tube blank. Stratification is divided into dominant and recessive. Dominant stratification can be judged by the naked eye without deformation. Invisible stratification can be seen only after deformation. Invisible stratification is more harmful than dominant.

 

Reasons for stratification:

(1) The oxide film on the surface of the molten steel is rolled into the inside of the steel ingot and is formed in the subsequent rolling.

(2) There is slag inclusion in the billet, which forms delamination after rolling.

(3) The necking and the parts below the necking during the solidification process of the molten steel are loose due to insufficient filling of the molten steel. The necking and looseness will form a layer or interlayer after rolling.

(4) Non-metallic inclusions. During casting, steel slag or refractory materials in the steel failed to float on the surface of the molten steel and were mixed in the steel ingot, and subsequent rolling formed delamination.

The effect of delamination on the quality of welded pipe:

(1) The tube blank is easy to deviate during the forming process, which leads to abnormal production. This is because when the layered tube is rolled by the upper and lower forming rolls of the open pass, the linear speeds of the upper and lower forming rolls are in fact not absolutely synchronized, so that the layered tube will slip irregularly.

(2) Affect the quality of welds. If the edge of the tube is stratified, after being formed into an open tube to be welded, the inner layer of the tube should be compressed and the outer layer should be extended, causing the layered edge to be misaligned, resulting in a dislocation of the weld, and the outer burr is difficult to remove.

(3) Even if a tube is produced from the hidden layered tube blank, if it is not discovered in time during the production process, it will be more harmful, making it difficult for the welded tube to withstand the pressure of the normal wall thickness.

 

Regarding the defects of welded pipe blanks of used high frequency tube mills (8), the causes of delamination and the effect of delamination on the quality of welded pipes, I hope it can help you.

2.Coil Carriages:These assist in loading and unloading coils onto the mandrels. Coil carriages help to position the coils correctly and securely.
3.Hydraulic System:This system is used to expand the mandrel to grip the inner diameter of the coil securely.
4.Control System:The electronic control system automates the switching between coils and ensures synchronization with the subsequent processing line.
5.Brake System:To control the speed of uncoiling and ensure smooth feeding into the processing line, a braking system (mechanical or pneumatic) is integrated.

Operation:
1.Loading:One coil is loaded onto a mandrel with the assistance of a coil carriage. The hydraulic system secures the coil.
2.Preparation:While one coil is being processed, the second coil can be prepared on the other mandrel.
3.Uncoiling:The control system manages the unwinding process, adjusting speed and tension to match the requirements of downstream equipment.
4.Switching Coils:Once the first coil is nearly depleted, the system can seamlessly switch to the second coil, ensuring continuous operation without stopping the line.
Advantages:
1.Continuous Operation:Allows for non-stop processing as one coil can be prepared while the other is being used.
2.Increased Efficiency:Reduces downtime and increases overall productivity in the metal processing line.
3.Improved Safety:Automated systems reduce the need for manual handling of heavy metal coils.
4.Precise Control:Advanced control systems provide precise management of coil unwinding, contributing to product quality and consistency.

Analyzing of High-frequency quenching equipment
Analyzing of High-frequency quenching equipment
High-Frequency Quenching Equipment AnalysisHigh-frequency quenching equipment is advanced machinery used in the heat treatment of metals to improve their hardness and wear resistance. This method involves heating the surface of a workpiece to a very high temperature using high-frequency electric currents, followed by rapid cooling (quenching). The process effectively enhances the mechanical properties of the metal components, making them suitable for high-stress applications. Here are some key points to analyze high-frequency quenching equipment:

1.Working Principle:
High-frequency quenching equipment utilizes induction heating, where alternating electromagnetic fields generate heat within the metal workpiece.
The frequency of the alternating current is typically between100 kHz and500 kHz, which effectively heats the surface rapidly while keeping the core relatively cool.

2.Components:
Power Supply:Generates the high-frequency current necessary for induction heating.
Induction Coil:The coil is designed to fit around or near the workpiece, creating a magnetic field that induces eddy currents on its surface.
Cooling System:Typically, a coolant (such as water or oil) is sprayed or immersed to rapidly cool the heated metal surface.
