DGZ Series Counter-axis Four-high Universal Rolling Mill/Turk Head/Universal Rolling Mill /FLAT AND PROFILE WIRE ROLLING MILL MACHINE CHINA
Uses: It is possible to perform high precision flat& shaped wires rolling experiments from round inlet wires.
Always used for rolling flat wire, square wire, rectangular and other profiled wires.
process: shapes can be cold-rolled if the cross-section is relatively uniform and the transverse dimension is relatively small. Cold rolling shapes requires a series of shaping operations, usually along the lines of sizing, breakdown, roughing, semi-roughing, semi-finishing, and finishing.
Cold rolling process occurs with the metal below its recrystallization temperature (usually at room temperature), which increases the strength via strain hardeningup to 20%. It also improves the surface finish and holds tighter tolerances. Commonly cold-rolled products include flat wires, flat strips, triangular wire, wedge wires, half-round wire and etc.
