argon gas uses detailed introduction
argon gas uses a wide range. Its nature is very inactive, neither burning nor combustion. In the aircraft manufacturing, shipbuilding, atomic energy and mechanical industries, special metals such as aluminum, magnesium, copper and their alloys and stainless steels are often used as welding shielding gas during welding to prevent the welding pieces from being oxidized or nitrided by air. In metal smelting, oxygen, argon blowing is an important measure to produce high quality steel. In addition, titanium, zirconium, germanium and other special metals smelting, and the electronics industry also need to use argon as a protective gas. Argon can also be used in the production of monocrystalline and polycrystalline silicon in the photovoltaic industry. As an inert gas, it surrounds the liquid surface of monocrystalline silicon and polycrystalline silicon as a protective gas to protect the monocrystalline and polycrystalline silicon from oxidation.
Argon mainly through the air separation plant will separate the different components of the gas in the air, extracted from the air. Although argon gas is widely used downstream, due to its extremely low proportion in air, an air separation plant usually has only a small part of argon capacity and a relatively limited capacity (the output of argon in the air separation unit accounts for a very large proportion Low, which can be understood as a by-product of the air separation unit), the downstream supply of oxygen, nitrogen and argon is often less available, resulting in a great price elasticity. Argon gas prices in the history of fluctuating between a few hundred thousand yuan.
