       wire section is small, long length, and the required dimensional accuracy and surface quality is high, which determines the wire production process has a series of characteristics.

       the characteristics of the blank, in order to ensure the termination temperature, to adapt to the needs of small diameter and heavy disk, in the billet allowable conditions, the cross-section should be as small as possible to reduce the rolling pass, to prevent the temperature is too high, so the general billet longer.

       heating characteristics, in ensuring the quality of heating under the premise of heating temperature as high as possible; the heating temperature of the various parts of the uniform, but the tail temperature is slightly higher to reduce the first temperature difference between the pieces; iron oxide skin to produce less to reduce burns and improve the surface quality of the pieces, in order to reduce the cooling, the furnace should be as close as possible to the mill.
