Detail

The external burr shape appears when the used steel pipe rolling 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 steel pipe rolling 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 steel pipe rolling 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 steel pipe rolling 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 steel pipe rolling 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 steel pipe rolling mills

 

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 used steel pipe is rolled by machine-made pipes. The essence of the running state of the used steel pipe rolling mills can be analyzed through the shape of the external burr.

In the welded pipe industry, people generally regard welded pipes with a wall thickness to outside diameter (thickness-to-diameter ratio) of 12%≤t/D≤18% as thick-walled pipes. Difficulties in used round pipe to square pipe machines, clearly put forward the adjustment methods of thick-walled tube forming.

In the production of used ERW tube mills, the roll is the key and important special tool. Roll consumption is also a key tool for manipulating product costs. In addition, the normal operation of the roll will directly affect the output and quality of welded pipe manufacturing. Therefore, welded pipe manufacturers attach great importance to and strive to improve the service life of the roll.
