Operation control points of air cooling line
1） Perform process operations strictly in accordance with the control parameter table
2）Strictly implement the coil collecting operation in the drum. When producing φ14/16 specifications, the collecting drum should be installed with positioning steel bars to ensure the coil shape.
Wire rod packaging and lifting control points
1） The packing pressure is controlled according to the specifications to ensure that no loose coils occur during the transportation of the steel coils.
Specifications | Φ6.5 | Φ8 | Φ10 | Φ12 | Φ14 | Φ16 |
packing pressure（ton） | 30~32 | 30~32 | 32~34 | 32~34 | 35~38 | 35~38 |
2）When producing φ14/16 specifications, a double-lane packing line should be used.
3） The disk hanger is wrapped with a thin iron sheet to prevent the sharp parts from scratching the wire rod.
4） Intermediate sampling is prohibited for this steel grade. In special cases, if the steel is cut in the middle, yellow paint should be painted at the fracture and a sign should be attached. When trimming the head and tail, trim off the ears and surface scars of the head and tail.
