【概要描述】The used high frequency tube mills is the core equipment of the entire HFW production line, and it is also the equipment with the highest technical requirements for the production line. If it is adjusted improperly, it will directly affect the quality of the welded pipe. This article takes five-roll extrusion welding as an example to introduce the used high frequency tube mills in detail. Common problems of high-frequency welding of machines (4)-the cause of the torsion of the weld.

Detail

The used high frequency tube mills is the core equipment of the entire HFW production line, and it is also the equipment with the highest technical requirements for the production line. If it is adjusted improperly, it will directly affect the quality of the welded pipe. This article takes five-roll extrusion welding as an example to introduce the used high frequency tube mills in detail. Common problems of high-frequency welding of machines (4)-the cause of the torsion of the weld.

 

Torsion of the weld seam of the used high frequency tube mills

 

Used high frequency tube mills

 

Causes:

(1) The height of the two welding side rollers is different, which can be corrected by adding or subtracting metal shims at the bottom or side of the horizontal roller frame.

(2) The roll positions of the two squeezing side rolls are asymmetrical along the rolling center of the welded pipe, which causes the two squeezing side rolls to exert unequal forces on the tube blank, which causes the tube blank to twist.

(3) The bearing or guide piece of the finish forming roll is damaged, resulting in the inability to control the torsion of the weld.

(4) The vertical adjustment of the guide roller position is too high, and only part of the guide roller pass is in contact with the billet, resulting in too little force applied to the tube billet, unable to control the torsion of the roller, or damage to the guide roller or bearing.

 

The above-mentioned problems are the reasons for the torsion of the weld seam caused by the used high frequency tube mills during high-frequency welding. I hope to give you effective help.
