Abstract
The application of continuous extrusion technology in the production of oxygen-free copper bar was described.Through adopting on-line degassing
new up-drawing continuous casting equipment with new mould and continuous extruded technology
the oxygen-free copper bar with oxygen content less than 0.0005%and electric conductivity more than 58.58MS/m was produced successfully by melting
up-drawing Cu bar
continuous extrusion
tensile and finishing.The technology exhibits short procedure
