      Washing solution with a temperature of up to 80°С.

      Hot air drying with a temperature of up to 120°С.

      Polishing by using the 200Х25Х76 CP-FB 5A MED brushes (CF-FB 5A VFN 3M flap brushes)

13) Polishing device with an aspiration system, having a spark arresting system and ignition protection

14) Two-plane straightening rolling device.

15) Double take-up device with precision laying function and tilter.

16) Device for the control of geometric parameters of the strip

17) Cooling and lubrication fluid filtration system with a magnetic separator.

18) Safety fencing with a locking system which restricts personnel's access to the running equipment

19) Electrical equipment:

     Electrical cabinet: IP54 protection, cooling by an air conditioner. Electrical cabinets should be located behind the machine drives. LED lighting inside the machine.

How Does Four Stand Cold Rolling Mill Produce DC01 Flat Wires?

This cold rolling mill is composed of four rolling stands arranged in tandem to produce DC 01 wire. Our company's newest high-precision rolling mill series from round wire to flat wire machine contains two or four rollers. Each stand passes the metal through two or four rollers. By using this setup, the wire's thickness will be gradually reduced while its physical properties, such as strength and finish, will be improved. Materials such as DC01 cold-rolled non-alloy steel are particularly suitable for this process.

DC01 Flat Wire: What is it?

The DC01 designation indicates a cold-rolled steel grade that meets the European standard EN 10130. The "DC" stands for "drawing quality cold-rolled steel," and the "01" indicates a particular grade within that category. A flat wire has a rectangular or other non-round cross-section after it has been flattened, usually by rolling processes.
