High-purity titanium ingot purification method

Abstract

The invention discloses a high-purity titanium ingot purification method. The method comprises the steps of preparation of materials, loading of the materials into a furnace and electron beam melting.An electron beam furnace is adopted for melting, the temperature is raised to start electron beam smelting when the vacuum degree of a hearth of the electron beam melting furnace is maintain to be higher than or equal to 2.0*10<-2> pa, the melting temperature is controlled to be higher than or equal to 2350 DEG C, the melting speed is controlled to be higher than or equal to 25 kg/h, a titanium strip is fully melted, and a titanium ingot formed after electron beam melting is cooled in the hearth and then discharged out from the furnace. The content of iron, silicon, carbon and other impurityelements is effectively reduced, correspondingly the high-purity titanium ingot is obtained, and high-purity metallic titanium has no pores and no impurities.

AI Technical Summary

Benefits of technology

This new technology allows for better control over how much aluminum oxide (Al2O3) needs to be removed during production compared to previous methods that used other materials like magnesite or calcium carbide. By controlling these factors, this process can produce highly pure metallic Ti products without any defects called pits or particles.

Problems solved by technology

This patents describes how we want to produce highly pure materials called tetrahedral Titanium (TIN) at very large scales without requiring expensive or complicated procedures like ion implantations. Current techniques involve producing these materials through complex multi-step chemical reactions involving several steps, leading to increased costs associated with each step. Therefore, new ways to make TIN have lower levels of impurites can reduce manufacturing time and improve quality.
