The nozzle defects of the used welded pipe production line are caused by flat heads, oblique heads, rubbing heads, and nozzle blockages. The following measures are put forward to solve the problems of nozzle defects.

Countermeasures for removing nozzle defects on used welded pipe production line:

(1)Countermeasures against flat heads:

①Select a thinner saw blade to reduce the friction resistance of sawing;

②Change the saw blade frequently;

③Appropriately reduce the pressure of the sawing cylinder to reduce the sawing rate;

④Change to a saw with more teeth piece.

(2)Countermeasures against head rubbing:

①Adjust the precision of the saw;

②Adjust the lifting time, loosening time and cutting time.

(3)Countermeasures against the inclined head:

①Adjust the main operating parameters of the flying saw, such as the first acceleration, the first deceleration and the synchronization adjustment time;

②Check the precision of the spindle bearing of the flying saw and the precision of the mechanical equipment of the drive.

③Check the flatness of the saw blade

(4)Countermeasures to deal with the clogging of the nozzle:

add frequent cleaning of the saw blade to the countermeasures to solve the oblique head.

The improvement of the quality of the sawing of the inner hole of the welded pipe will create a resource advantage for the subsequent casting and rolling of the welded pipe such as small flat ends and rounded corners.

The above is to solve the improvement measures for nozzle defects after the flying saw is disconnected in the used welded pipe production line. I hope it will be of some help to you.
