carbon erw pipe mill

,

square erw pipe mill

,

rectangular erw pipe mill

 

This equipment is in order to meet the requirements of the international market, according to our company LW series unit combined with FF forming technology,developped the automatic square and rectangular tube mill line.

 

 

 

,

The main characteristics of the equipment:

In a very short period of time to finish the adjustment of the roller, extreme reduce the roller change time when replace the products, thus improve the efficiency and reduce the productive cost;

 

Due to the equipment adopts one set of combined mould, producing the different specifications of the tube, only need to adjust,no need to change,the roller savings rate at above 90%,thus reducing the cost of the roller;

 

Due to the equipment adopts the motor automatic adjustment,thus decreasing the number of workers,reduce the labor costs,decreased the workers labor intensity, improved the workers working environment;

 

The equipment operation is simple,just need to know the size and the wall thickness of the tubes in the production,then input it to the interface,it will make adjustment automatically, thus lower levels of debugging personnel's technical requirements.

 

With automatic adjustment, decreased the input of tools and damage to equipment when change the roll, improve the service life of the equipment.

 

Due to structure of the composite roll,the point contact between the roll and strip instead of the original line contact,reduce the roll wear and improve the service life of roll.

Can produce a certain specification of opening cold bend steel, such as U,C section steel etc., width and height of the product can be adjusted infinitely.

The equipment consists of the following parts:

1,Single Mandrel Hydraulic Decoiler

 

The decoiler is mainly composed of base, increases cone head, hydraulic system, hydraulic brake, to increases and cantilever type single drum, a conical head, one online;Hydraulic ncreases,hydraulic brake.

OD of coil Φ1000-2000mm
ID of coil Φ520-610mm
Width of strip 100-400mm
Thickness of strip 1.5-4.0mm
Weight of strip Max10T
Expansion Type Hydraulic expand
Break Hydraulic driving

 

 

 

 

 

 

2,End straightener:

 

This unit is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place.

electric motor power:1.5KW

processing pressure:7Mpa

reduce speed :BW17-4

 

3,Flattener:

This unit is main used to flatten the head and trail of the strip steel and prepare for the next step cutting and shear welding so as to ensure the strip steel opposed flate and straight in the shear welding.

flattener level and pressing capability:

the flattener & pressing roll Dia:Φ120

flattener roll Dia:Φ100

flattener level velocity:11m/min

the style of the adjust velocity: no grade of the adjust velocity

the structure style:pressing & carry, five roll flattener unit

  1. , Horizontal spiral accumulator

 

This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.

 

 

 

It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.

(2)

Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.

(3)

Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.

(4) technical parameters:

working style: Fixed circle

advantage: storage material more, no strike to strip steel suface.

steel coil thickness:1.5-4.0mm; width:100-400mm

carry material going velocity:Vmax=120m/min

hydraulic oil pressure:7Mpa

directly electric motor power of the press & carry:22KW

the electric motor of the accumulator frame : 37KW
