The ZJ-type series cold-rolled ribbed steel bar equipment production line is a processing device that cold-rolls and reduces the diameter of hot-rolled coiled steel bars ranging from Φ6.5 to Φ12 millimeters, followed by cold-rolling the surface to form three-sided crescent transverse ribs. The produced ribbed steel bars can meet the GB13788—2000 standard.

 1. Equipped with a uniquely designed wire drawing drum, it operates without lubricating powder or fluid, reducing costs and enabling

 dust-free production.

2.This series of cold-rolling equipment can be fitted with alloy drums and a horizontal heavy-duty wire drawing machine, offering easy threading and simple adjustment. It avoids issues such as wire breakage due to improper adjustment and unstable product quality.

3.The machine uses steel wear-resistant drums, eliminating the frequent need for welding and grinding of drums.

4.For diameter reduction of about 1 mm, a single wire drawing machine can be used, making operation simpler and more energy-saving.

5.Both rolling mills feature an all-steel structure, providing high load-bearing capacity and durability without damage.

6.The unit is equipped with an AC asynchronous stepless speed regulation motor, featuring a simple control circuit, high reliability, nearly maintenance-free operation, and ease of control. It can also be configured with variable frequency speed regulation.

Note: The ZJ series can only produce cold-rolled ribbed steel bars in coiled form. If straight bars are required, please choose the ZT series products or equip the machine with a straightening device.
