Preparation method of titanium-zinc alloy and titanium-zinc alloy plate

Abstract

The invention provides a fabrication method of a titanium-zinc alloy. The fabrication method comprises the following steps that after a part of pure zinc is molten to form a molten pool, the balance pure zinc is added; after the whole pure zinc is molten, heating to 450 degrees is performed, and a zinc-copper-titanium ternary intermediate alloy is added; after the zinc-copper-titanium ternary intermediate alloy is added wholly, a covering agent is spread on the surface of a melt uniformly; after the whole zinc-copper-titanium ternary intermediate alloy is molten, a refining agent is added, and mixing refining is performed on the condition of the temperature not exceeding 450 degrees; and after dirt and dross are removed, casting is performed, and a titanium-zinc alloy ingot is obtained. With the adoption of the fabrication method, a casting process can be simplified, and the production efficiency can be improved; the fabrication method is simple, safe and reliable, and is convenient to operate; and the finally fabricated titanium-zinc alloy plate has no defect on the surface, has better mechanical property and higher market competitiveness, and is suitable for popularization in scale industrial production.

Description

technical field [0001] The invention relates to a preparation method of a titanium-zinc alloy and a titanium-zinc alloy plate, belonging to the technical field of metal smelting. Background technique [0002] As a new type of green building material, titanium-zinc plate building roofing materials have gradually entered the Chinese building material market. The domestic comparable products are limited to color-coated steel plates, while the products made of zinc in Europe and the United States have been used on roofs for nearly 200 years of history. For buildings with higher service life and quality requirements, the overall anti-corrosion and titanium-zinc panels with a service life of more than 100 years are the first choice of architects all over the world. Titanium-zinc plate is an alloy, which is smelted by adding titanium and copper to high-purity Z1-grade metal zinc (purity 99.995%) that meets the European quality standard EN1179. Copper adds to the mechanical streng...

Problems solved by technology

[0003] At present, there are no literature and patent reports on the casting and rolling process of zinc-copper-titanium alloys in China. Since the melting point of zinc is far lower than that of copper and titanium, and there is a certain burning rate of zinc and titanium, if directly using pure The smelting of zinc-copper-titanium alloys will have the problem of difficult or incomplete melting of copper, and it will also make it difficult for the copper and titanium components to be evenly distributed into the alloy, which will not achieve the desired effect. Repeated smelting will inevitably increase the production cost. improve

At present, two binary alloys of zinc-copper and zinc-titanium are often added to the zinc melt, but there is often a problem that it is difficult to control the ratio of copper and titanium, and the melting and casting are complicated, the melting and refining time is long, a large amount of smoke and dust are generated, and the pungent odor is released. Deteriorating the operating environment, while damaging the health of the workers, and causing pollution to the surrounding environment (Geng Haoran, Wang Shouren, Wang Yan, etc. Casting zinc and copper alloys [M].
