Detail

The external burr shape appears when the used pipe tube mills. The shape of the burr inside the welded pipe has a certain logical relationship with the welding temperature, extrusion force and welding speed.

The operator can see the essence of the operating state of the used pipe tube mills through the phenomenon of the shape of the external burr.

Correlation between matching state of speed, temperature, extrusion force and external burr shape

Used pipe tube mills

External burr shape: bifurcated

Speed and temperature extrusion force matching status: welding heat is too low, welding speed is too fast, and extrusion force is too small.

Adjustment measures: immediately reduce the speed or increase the welding heat or increase the extrusion force.

Used pipe tube mills

External burr shape: linear

Speed and temperature extrusion force matching status: welding heat is low, welding speed is high, and extrusion force is low.

Adjustment measures: increase the welding heat or reduce the speed or increase the squeezing force appropriately.

Used pipe tube mills

External burr shape: small hilly shape

Speed and temperature extrusion force matching state: maintain current operation.

Adjustment measures: normal production + pay attention to observation

Used pipe tube mils

External burr shape: large hilly shape

Speed and temperature extrusion force matching status: welding heat is too high, welding speed is too low, and the extrusion force is too large.

Adjustment measures: Immediately reduce the welding heat or accelerate, or appropriately reduce the squeezing force.

The above are the types of external burrs that appear when the second-hand steel pipe is rolled by machine-made pipes. The essence of the running state of the used pipe tube mills can be analyzed through the shape of the external burr.
