1.Smelting process: in the process of steelmaking blowing high purity oxygen, oxygen and carbon and phosphorus, sulfur, silicon and other oxidation reaction, which not only reduces the carbon content of steel, but also conducive to the removal of phosphorus, sulfur, silicon and other impurities. Moreover, the heat generated in the oxidation process is sufficient to maintain the temperature required for the steelmaking process, so oxygen blowing not only shortens the smelting time, but also improves the quality of steel. When making iron in blast furnace, increasing the oxygen concentration in blast air can reduce coke ratio and increase output. In non-ferrous metal smelting, oxygen enrichment can also shorten the smelting time and increase the yield.
2.Chemical industry: In the production of synthetic ammonia, oxygen is mainly used in the oxidation of feedstock gas to strengthen the process and increase the yield of fertilizer. Another example is the high temperature cracking of heavy oil and the gasification of pulverized coal.
Defense industry: LIQUID oxygen is the best propellant for modern rockets, and it is also needed as an oxidant in supersonic aircraft. Combustible substances impregnated with liquid oxygen have strong explosiveness, and liquid oxygen explosives can be made.
3.Medical care: Supply breathing: used in anoxic, low oxygen or no oxygen environment, such as: diving operations, mountaineering, high altitude flight, space flight, medical rescue, etc.
4.Other aspects: it itself as an accelerant and acetylene, propane and other flammable gases with use, to achieve the role of welding and cutting metal, all walks of life, especially in mechanical enterprises are widely used, as a cutting is also very convenient, is a preferred cutting method.
