cold rolling line, 1)make various specification rebar, 2)materials:hot rolled wire steel rods, 3)dia:5-14mm, 4)power:110kw - details see: https://www.machineto.com/2-roller-cold-steel-bar-rolling-line-for-wire-round-steel-bar-10130650

use:

This kind of cold rolling line is used tomaking different specification rebar.

working principle of cold rolling line:

First reduces the diameter of the hot rolled wire steel bars, and then makes ribs on bars by cold rolling mill.

The milling line can make the steel barHRB335,HRB400 and HRB500as your requirement. The final productions are 2 ribbed rebar or 3 ribbed rebar.

specification:

There are three types : small type (mean the production diameter belowΦ10mm) of the cold rolling mills, medium-sized (mean the production diameter belowΦ12mm) and large type (mean the production diameter belowΦ14mm)of cold rolling mills.

the parameter of cold rolling mill:

Project	Technical parameter	Unit	Supplementary details
Raw material	Φ6.5-14	mm
Roller diameter	Φ228	mm	Special-purpose alloy
Equipped with power	75	KW	YVP200-4 variable-frequency Variable-speed motor
Gear center distance	228	mm	Herringbone gear
Rolling line speed	max3	M/s
Sheared length	1-12	m
Flying shear	5.5	KW
Product specification	Φ5-14	mm
Output	1.6-17	T/h

The final product are 2 ribs or 3 ribs deformed steel bar in circular shape or in line shape.

The whole set of cold rolling line were composed with:

1. Pay-off machine

2. Dephosphorization (detach the scale) and sinking mill (the first time to roll) at the first time

3. Rolling mill

4. Straightening machine

5. Heat treatment (in consideration of you need a low strength close to 500 MPA, we add this machine to strengthen the steel extensibility)

6. Cutting machine (the cutting length on the basis of your set , its speed 1.5-3m/s,it can cut below 12mm or 10mm reinforced steel bar, the final production in line shape)

Or wire re-winding machine (the final productions are in circular shape)

7. Flick rack (most of them we have sold are 9 meters or 12 meters long, of course we can produce according to your requirement). Its automatic, the power is1.5 KW

8 Synthetically control panel.

The line speed can be 3m/s,

This set of machine is automatic, only need two or three man, one is to control the synthetically control panel, the second is to weld steel coil and bundle the final productions.
