Description

Technical Field

[0001] The present invention relates to the technical field of metallurgy, in particular to a method and equipment for continuously producing metallic titanium or metallic titanium alloy. Background Art

[0002] Titanium alloy is a metal material composed of titanium and other alloying elements, usually including aluminum, vanadium, molybdenum, iron and other elements. Different performance characteristics can be obtained by adjusting the alloy composition and heat treatment process. Its density is about 4.5g / cm³, and its specific strength is significantly higher than that of aluminum alloy and steel. At the same time, it has excellent corrosion resistance and is highly stable to seawater, wet chlorine and various acid and alkali environments at room temperature. Its melting point reaches 1668℃ and it still maintains good mechanical properties at high temperatures. Its biocompatibility makes it non-toxic and side effects in the human environment. This type of alloy can achieve performance customization from high plasticity to high strength through α+β phase transformation regulation. It is now widely used in the aerospace field as structural load-bearing parts, the medical field as human implant materials, the chemical field as corrosion-resistant equipment components, and the manufacturing of lightweight automotive components. Its comprehensive performance makes it an important choice to replace traditional metal materials in modern industry.

[0003] Traditional titanium or titanium alloy production equipment generally uses a single roller or simple extrusion equipment for conventional crushing operations in the crushing of titanium fragment raw materials. It is unable to evenly crush large pieces of titanium fragments, resulting in uneven raw material particle size and low crushing efficiency. This can easily cause instability in subsequent smelting or processing, affecting product quality. In addition, the screening process lacks automation and must rely on manual intervention to separate large pieces of fragments that are not completely crushed. This not only increases the labor intensity of the staff, but also causes frequent production interruptions due to fragment accumulation or blockage, destroying continuity. Secondly, the raw material recovery mechanism is imperfect. After qualified debris is mixed with unqualified fragments, it cannot be automatically recycled and crushed, resulting in raw material waste and equipment downtime, and unable to guarantee stable input.
