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. The preparation method comprises the steps of adding simple substance Y, Y2O3 or the mixture of Y and Y2O3 to sponge titanium for mixing, and smelting in a vacuum smelting furnace to cast into a titanium ingot, wherein the mass ratio of the Y element to the sponge titanium is (0.04-4.0): 1. When the titanium alloy prepared by use of the method is applied to preparing a titanium plate, the titanium plate is evener in structure and refined in grain; and the material shows excellent dimensional processability 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...
