Roller die technology substituted for drawing die of tungsten steel was utilized to draw copper alloy strip. The structure of roller die with long service life

high precision and reliability was designed combined with coiling or chain drawing machine to drawing copper alloy strip. The results indicate that the surface quality and flatness of copper alloy strip can be significantly improved by roller die technology

and the energy saving is about 22%. Compared with rolling mill

the roller die with simple structure is convenient to maintain and adjust

and roll dies with different hole patterns can be suitable for a variety of specifications of Cu alloy strip.
