● Tensile strength: δb≤450Mpa, δS≤260Mpa

● Flat bar thickness: 2mm-8mm

● Flat bar width: 20mm-100mm

b. Finished parameters

● Precision of width: +0.3~-0.9mm

● Precision of fixed length: 0~+5mm

● Bending: ≤2.5mm/m

● pitch of cutting: ≤2mm

c. Other parameters:

● Line speed: 20-25m/min

2. Brief introduction of the line

a. Simplified de-coiler

● It adopts the de-coiling device to expand and shrink manually which could expand from φ300 to φ350

● It has the device to block the coils to prevent they from loosing

● It is equipped with the brake devices to control the tension of de-coiling and avoid inertia which may cause the coils spring-shaped open

b. 7 roller-straightener

● It is divided into 2 pinch rollers and 5 leveling rollers

● 2 pinch rollers can eliminate part of the bur after the shearing, while the 5 leveling rollers pre-leveling the plate to feed the flat bar more easily

● The diameter of the rollers isφ85 without power and both sides of the rollers are adopted the roll bearing to support

c. Chamfering and extrusion machine

● It adopts the 12 stand roller which are divided into 6 groups , 3 groups on one side and press and squeeze each side to do the chamfering and edging

● This part can make the sharp edge to blunt so that forming the sides of the flat bars

d. 2 roller-pinch and press device

● It is driven by drive which is same with the straightener , with the reason driven rato to achieve synchronize

● It is equipped with gear distribution box

● The diameter of the two rollers are 180, they are used to pinch and press and polish the surface

e. Longitudinal straightener

● 5 stand rollers to straighten the flat bars longitudinal bending

f. Flat surface straightener

● It is equipped with 15KW frequency conversion control motor with decelerator

● It is composed of 2 pinch rollers and 11 leveling rollers

● The motor change to frequency conversion control which is cheaper and with a perfect speed and length

g. Hydraulic tracking cutting machine

● The machine is applied to the cutting of the flat bars

● It do the incessantly shearing to advance the efficiency and the even quality

h. Fixed length receive table

● The table is designed to 6m

● Equipped with 6m unload table (which can customized according to customers' specific requirements)

● Equipped with the hooks to tie up the finished bars which is convenient to stack and tie the flat bars( pneumatic balers and the gas should be prepared by the customer)

i. Electrical control system: 1 unit

● Control the working of all the electro motors of the devices (speed control and synchronize)
