The application of oxygen (1)
Oxygen is the living material on the earth, it is easy to react with other substances to form oxides, in the process of oxidation reaction will produce a lot of heat. Therefore, oxygen is widely used in life, metallurgy, chemical industry, energy, machinery, national defense industry and other departments. The following Xiaobian will give you a simple introduction to the use of oxygen.
Properties of oxygen
Oxygen is a colorless, tasteless gas, insoluble in water, density than air, support combustion, solid are light blue. It is easy to react with other substances to form oxides, in the process of oxidation reaction will produce a lot of heat.

Use of Oxygen
1, in the process of steel blowing with 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. The heat generated is sufficient to maintain the temperature required for the steelmaking process, shortening the smelting time and improving the quality of the steel. The coke ratio can be reduced and the output can be increased by increasing the oxygen concentration in blast furnace.
2, heavy metal smelting, fire smelting plays a major role, in addition to sulfur and iron oxidation exothermic, but also need to rely on fuel combustion to provide heat. In order to strengthen the smelting process, reduce energy consumption, reduce the amount of harmful smoke, the use of enriched oxygen instead of air smelting, at the same time can improve the production capacity of the equipment.
3, in the production of synthetic ammonia, oxygen is mainly used for the oxidation of feed gas. For example, high temperature cracking of heavy oil, and gasification of pulverized coal, to strengthen the process and increase fertilizer yields.
4. Liquid oxygen is the best combustion-supporting agent of modern rockets. Liquid oxygen is also needed as an oxidant in supersonic aircraft.
