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.

A hot-spinning formation method for large-diameter titanium alloy cylindrical parts. A workblank is placed in a resistance furnace to heated to 600-650&#xb0; C., is maintained at this temperature for 0.5-1 h and is then taken out of the resistance furnace; after the workblank is heated, the inner diameter of the workblank becomes larger; the heated workblank is installed on a mandrel, and spinning is started when a maximum clearance between the workblank and the mandrel is less than 0.5 mm; the mandrel and the spinning rollers do not need to be preheated, and a multi-pass spinning process is adopted, such that the workblank can deform more uniformly. A vertical spinning lathe is used for spinning, the mandrel is easy to change, and the workblank is easy to assemble and disassemble.
