The wire section is small, the length is long, and the required dimensional accuracy and surface quality are high, which determines that the wire production process has a series of characteristics.
The characteristics of the billet, in order to ensure the final rolling temperature, adapt to the needs of small wire diameter and large coil weight, the section should be as small as possible under the conditions allowed by the billet supply, in order to reduce the number of rolling passes and prevent the temperature from being too high, so the billet is generally longer.
Heating characteristics: On the premise of ensuring the heating quality, the heating temperature should be as high as possible; the heating temperature of each part is uniform, but the temperature at the tail is slightly higher to reduce the temperature difference at the first point of the bundle; the formation of iron oxide scale should be less to reduce burning loss and improve In order to reduce the cooling, the heating furnace should be as close as possible to the rolling mill.
