Method for making titanium cathode roller member

Abstract

A method for manufacturing a titanium cathode roller body, first roll a titanium plate into a cylinder and weld the seam; heat the weld seam and the heat-affected zone, the temperature is controlled between 750-950 ° C, and the non-deformation The base material part should be cooled and protected, and the welding seam should be upset and then forged flat; then the weld seam and the heat-affected zone should be heated, and the temperature should be controlled between 750 and 950 °C, and the non-deformed base material part should be cooled and protected , then upsetting the welding seam and then forging it flat, repeating it many times, so that the welding seam is deformed many times, and the deformation amount should be more than 30% each time; for the heat treatment of the deformed part, the temperature is controlled between 750 and 850 °C . The invention transforms the cast structure into an equiaxed structure that is basically the same as the substrate structure, thereby eliminating the periodic bright bands printed on the foil by the weld structure and meeting the production technical requirements of the foil , low cost, high quality, wide range of applicable specifications.

Description

technical field [0001] The invention relates to a method for manufacturing a titanium cathode roller body. Background technique [0002] When producing metal foils such as copper and nickel by electrolysis, titanium cathode rollers are required. The quality of the cathode roll directly affects the quality of the foil. At present, there are mainly two methods for manufacturing the titanium cathode roller body. One is to use plate roll welding. There is a longitudinal weld on the titanium cylinder. The weld structure will be printed on the foil, forming periodic bright bands, which directly affects the quality of the foil. The other is to make a seamless titanium cylinder by forging, ring rolling, and spinning. The titanium cylinder has no longitudinal welds, which meets the technical requirements for foil production, but this method requires large-scale special equipment and has high production costs. In addition, users of cathode rolls want high surface finish and long se...

The other is to make a seamless titanium cylinder by forging, ring rolling, and spinning. The titanium cylinder has no longitudinal welds, which meets the technical requirements for foil production, but this method requires large-scale special equipment and high production costs.

In addition, users of cathode rolls want high surface finish and long service life, so they must have higher hardness of the roll material. The increase of hardness must increase the strength of the material, and the increase of strength will bring difficulties to ring rolling and spinning
