The chemical properties of oxygen are more active. Except for rare gases and metal elements with low activity such as gold, platinum, and silver, most of the elements can react with oxygen. These reactions are called oxidation reactions. One element is oxygen) called oxide. Generally speaking, aqueous solutions of non-metal oxides are acidic, while alkali metal or alkaline earth metal oxides are alkaline. In addition, almost all organic compounds can burn violently in oxygen to produce carbon dioxide and water. In chemistry, the chemical reaction between a substance and oxygen was defined as an oxidation reaction, and a redox reaction refers to a reaction in which electrons are transferred or shifted. Oxygen has combustion-supporting and oxidizing properties.
Smelting process: In the steelmaking process, high-purity oxygen is blown, and the oxygen reacts with carbon and phosphorus, sulfur, silicon, etc., which not only reduces the carbon content of steel, but also helps to remove impurities such as phosphorus, sulfur, and silicon. . Moreover, the heat generated in the oxidation process is sufficient to maintain the temperature required for the steelmaking process. Therefore, oxygen blowing not only shortens the smelting time, but also improves the quality of the steel. In blast furnace ironmaking, increasing the oxygen concentration in the blast can reduce the coke ratio and increase the output. In non-ferrous metal smelting, the use of oxygen enrichment can also shorten the smelting time and increase the output.
Chemical industry: In the production of synthetic ammonia, oxygen is mainly used for the oxidation of raw gas to strengthen the process and increase the output of chemical fertilizers. Another example is the high-temperature cracking of heavy oil and the gasification of pulverized coal.
National defense industry: Liquid oxygen is the best combustion-supporting agent for modern rockets. Liquid oxygen is also needed as an oxidant in supersonic aircraft. The combustible material is very explosive after being impregnated with liquid oxygen and can be used to make liquid oxygen explosives.
Medical care: supply breathing: used in hypoxic, hypoxic or anaerobic environments, such as diving operations, mountaineering, high-altitude flight, space navigation, medical rescue, etc.
Other aspects: it is used as a combustion aid in conjunction with acetylene, propane and other combustible gases to achieve the role of welding and cutting metals. It has a wide range of uses in various industries, especially in machinery companies. It is also very convenient for cutting and is the first choice. A cutting method.
