Abstract

See full text

A large-width cathode roller for producing high-strength ultra-thin copper foil includes titanium side plates and a titanium cylinder sealed by the titanium side plates, and a cathode roller core penetrated through the titanium side plates. Steel-copper explosive clad cylinders and a steel support plate are disposed in/on the side plate, inner ring surfaces of the side plates and the copper plates are connected to a copper sleeve around the cathode roller core, outer ring surfaces of the copper plates and the steel support plates are connected to a copper cylinder, inner ring surfaces of the steel support plates are connected to the cathode roller core; and multiple electrically conductive support rings on the copper cylinder are connected to the copper plates on two sides through the electrically conductive copper bars to form a conducting loop to improve the distribution uniformity of the current on the surface of the cathode roller.
