Description:

ROLLING MILL OF WIRE ROD PRODUCTION LINE

Used Secondhand Raw Materials: Billet 130x130mm or 160x160mm.
Finished product:φ5.5 ~ 17mm wire rod,
Comprehensive production capacity: 300,000T/ Per year.
Design speed:125m/s, practical speed: 90m/s.
Equipment condition: The whole wire rod line was designed & manufactured by our
company in 2013, and ran around 5 years, then standby, all machinery are almost the
new ones, our company will repair, update and refurbish all equipment.
Steel Grade: low alloy steel, high carbon steel, plain carbon steel, welding rod steel,
etc.
Production features: The whole line shall be 28 stands of rolling mill, including 16
stands roughing mill and intermediate rolling mill, DANIELI type short stress rolling
mill, vertical and horizontal arrangement, 2 stands of φ285 type pre-finishing mill,
vertical and horizontal arrangement, and 10 stands Morgan type finishing mill, 45°
top across arrangement.
Production process:
The qualified billet shall be delivered to reheating furnace through roller table,
6
heated to 1150℃, then pushed out via steel pusher, and into 8 stands roughing mill
(φ550×6+φ420×2, one motor with one mill) via roller table to carry out rolling
work. After cutting with No. 1 flying shear, the steel pieces shall be rolled in 2 stands
φ285 pre-finishing mill (Morgan type, horizontal & vertical structure), then rolled in
10 stands finishing mill to produce the finished product（8〞×5+6〞×5, Morgan
type, 45°top across arrangement ) while cutting with No.3 flying shear & chopping
shear. The final product wire rod will be collected, delivered from PF line, packaged,
unloaded, weighted and stored after water cooling system, pinch roll, laying head.
