3-roller type Y is a kind of continuous rolling mill, consisting of No.6, No.8 No.12; the rollers form an angle of 120°, like “Y”

This technology reformed the old producing method and deforming method. Under the applied forces of three rollers, the copper rod always in the state of three-dimensional stress. This stress restrained the free with of the ingot. The odd number stands forms the ingot are triangle, and even number stands form the ingot round. Great total compression can be adopted to gain a big deformation. So the arrangement of the stresses along the rolling direction is better than pulling mould, to make the final rod having a larger density and conductive ability, the plasticity of the rod is even better. In cold rolling process, great total compression can be adopted, so process can be simplified, the process of annealing and washing by acid can be omitted. As a result, the power consumption and raw material consumption can be reduced. This help to improve the productivity and shorten the producing cycle, and per capital production is increased, the product is better. As the technology of cold rolling is popularizing, type Y rolling will take place of large drawing bench and cold drawing bench. It is better equipment for producing copper rod with rejected red copper instead of copper cathode
