Abstract

Production technology of continuous conforming for oxygen-free copper strip was introduced. Adopting large continuous conforming equipment

reversible cold roller with high precision and finished annealing furnace

through melting

up-drawing continuous casting copper rod

continuous casting-extruding copper strip billet-rough rolling-finish rolling-annealing-clean

oxygen-free copper strip was produced successfully. In the copper strip

Cu and Ag content is more than 99.99%

and oxygen content is less than 0.0005%

and electric conductivity is more than 58.58 MS/m with tensile strength of 235 MPa and elongation of 50.5%. The technology exhibits the advantages of short procedure

high efficiency and high production yield as well as low cost.
