Laying head Used for Wire Rod Rolling Mill Production Line factory introduces the causes of machine problems
Laying head Used for Wire Rod Rolling Mill Production Line factory tells you the analysis of the reasons for the poor loop formation of the wire rod at the exit of the laying machine.
The spinning circle is poorly formed, the circle is disordered, and the position of the coil is erratic. Confusion in spinning will cause problems such as hanging steel on the Stelmo wire, blocking steel on the collection drum, difficult finishing and poor product quality. The reasons are as follows:
Tension and velocity fluctuations.
Laying head Used for Wire Rod Rolling Mill Production Line factory reminds you: The speed fluctuation of the finishing mill and the reducing and sizing mill will cause the speed fluctuation of the rolled piece, which will cause the tension fluctuation between the stands; the adjustment of the roll gap and material shape on site will cause the tension Changes; due to material shape defects and other reasons will also cause tension changes; improper speed configuration of the reducing sizing machine, pinch roll, and laying machine, resulting in the establishment of a constant micro-tension state of the rolled piece. These reasons will cause the speed of the rolled piece to be fast or slow, resulting in uneven coil size.
Roll line centering adjustment deviation.
Laying head Used for Wire Rod Rolling Mill Production Line factory tells you: the installation quality of guide grooves, guide guards, spinning tubes, spinning discs, etc. is not high, resulting in poor alignment of rolling lines; online spare parts are not replaced in time due to corrosion and wear , which brings the adjustment deviation of the rolling line. As a result, the operation of the rolled piece is unstable, and the shape of the spinning ring is chaotic.
