Loops for the High Speed Wire Rod Mill Line

Loops for the high speed wire rod mill line

The effect of Vertical loop:

wire-rod has the problem of the dynamic tension fluctuation caused by interference when it is in the process of rolling, so it lead to the fluctuation of the dimension of the rolling element, vertical loop can eliminate part of the tension fluctuation to make sure the precision of the equipments.

1. The structure of Vertical loop:

Vertical loop is composed of sets of roll(it is pushed by cylinder), back-up roll and loop groove. The sets of roll used to form cover. Side-wall is used to support the element to form the loop. Loop adopt the central pole mount, which is easy to turn on and adjust the mill guide and guard 

The diameter of sets of roll cylinder is Φ160mm; distance is 200mm.

The working altitude of loop is 100mm higher than the rolling centre line.

The highest altitude of loop is 400mm higher than the rolling centre line.  

2, Lubrication and pneumatic:

 The transmission parts of loop adopt glycerol manual lubrication.

 The air used in loop and rear brakes is unified offered by workshop, the pressure to compressed air is around0.4~0.6Mpa. 

The effect of Side loop:

wire-rod has the problem of the dynamic tension fluctuation caused by interference when it is in the process of rolling, so it lead to the fluctuation of the dimension of the rolling element, side loop can eliminate part of the tension fluctuation to make sure the precision of the equipments.  

1.The structure of side loop:

Side loop is composed by cylinder, sets of roll, loop platform, turning roll and loop scanner. Cylinder push the sets of roll. Sets of roll is mainly combined by the roll on the rocker. When the sets of roll is in the location of retraction, roll fully withdraw the rolling line, the tip of roller can directly get into the finishing mill through loop platform. When the sets of roll turn to the extended position, it forward to the rolling line and push the rolling element to loop platform, then the loop is formed.

The diameter of sets of roll cylinder is Φ130mm; distance is 254mm. 

The working altitude of loop is 300mm. 

The highest altitude of loop is 700mm. 

2.Lubrication and pneumatic: 

 The transmission parts of loop adapt glycerol manual lubrication. 

 The air used in loop and rear brakes is unified offered by workshop, the pressure to compressed air is around0.4~0.6Mpa.
