Problems solved by technology

[0005] 3. Although industrial pure titanium TA1 has good corrosion resistance and processing performance, its hardness and rigidity are relatively poor. Regular removal of residues on the surface of the cathode roller, corrosion layer and post-processing work such as grinding processes require the surface of the cathode roller The material must have the advantages of high plastic deformation resistance, high hardness, and excellent wear resistance. In actual production, such shortcomings also appear

Abstract

The invention discloses a preparation method of a titanium alloy, which comprises the following steps: adding elemental Y, Y2O3 or a mixture of elemental Y and Y2O3 into sponge titanium for mixing, melting and casting titanium ingots in a vacuum melting furnace; the Y element and The mass ratio of the titanium sponge is 0.04-4.0:1. When the titanium alloy prepared by the method is used to prepare the titanium plate, the structure of the titanium plate is more uniform, the crystal grains are refined, and the material shows good dimensional processing performance and structural stability.

Description

technical field [0001] The invention belongs to the technical field of metal titanium smelting, and in particular relates to a preparation method and application of a titanium alloy. Background technique [0002] With the rapid development of my country's electrolytic copper foil industry, the demand for cathode rollers, the key equipment for copper foil production, is also increasing year by year, especially the demand for large-scale titanium cathode rollers with high electrolysis efficiency is also increasing year by year. The cathode roller is called the mother of electrolytic copper foil, because the copper foil is the continuation of the crystal on the surface of the cathode roller, and is the mirror image of the surface of the cathode roller. The crystal grains on the surface of the cathode roller are fine, and the crystallization of the copper foil is fine. On the contrary, the crystallization of the copper foil is fine. thick. Therefore, it is required that the mic...
