Oxygen is a colorless and odorless gas. It is not easily soluble in water. It has a density greater than air and supports combustion. The solid is light blue. It easily reacts with other substances to produce oxides. A lot of heat is generated during the oxidation process. Let us look at the storage temperature requirements for oxygen cylinders.

In the steelmaking process, high-purity oxygen is blown, and the oxygen will oxidize with carbon, phosphorus, sulfur, and silicon, which not only reduces the carbon content of steel, but also helps to remove phosphorus, sulfur, silicon and other impurities. The heat generated is sufficient to maintain the temperature required for the steelmaking process, shorten the smelting time, and improve the quality of steel. In blast furnace ironmaking, increasing the oxygen concentration in the blast can reduce the coke ratio and increase the output. How to use a portable oxygen cylinder? When using an oxygen cylinder, turn the hand wheel counterclockwise to open the oxygen valve, and turn clockwise to close the valve. To open the valve, the operator should stand behind the valve and move slowly. After the valve is opened, observe the pressure gauge to see if the pressure in the bottle can be used. The wearer can wear a mask. The air exhaled from the lungs can enter the cleaning tank through the mask, tee, exhalation hose and exhalation valve. After the absorbent in the cleaning tank sucks out the carbon dioxide in the gas, the remaining gas enters the airbag; in addition, the oxygen stored in the oxygen cylinder can enter the airbag through the high-pressure pipe and the pressure reducer.

The oxygen bottle should take sun protection measures, and the ambient temperature during use should not exceed 40°C. Requirements for storing oxygen bottles:

1. Anti-explosion: In summer, sheds should be set up to protect the bottle from direct sunlight;

2. Rainproof: The storage point is set at a high place, and the bottle is protected from rain and ground water to rust the bottle.

3. Lightning protection: The storage point should be far away from lightning rods and lightning protection grounding devices of high-rise buildings, and keep a distance of more than 10 meters from them;

4. Prevent oil pollution: the storage point should keep a distance of more than 10 meters from the oil storage tank;

5. Anti-static: The storage point should be far away from overhead high-voltage lines and underground cables to prevent greater accidents when the cable fails

6. Heat source protection: The storage point should be far away from the heating tube and sheet to prevent heat source radiation;

7. House collapse prevention: storage points shall not be built near dangerous houses or temporary houses, and compressed gas cylinders shall not be stored;

8. Fire protection: The storage point should be kept at a distance of more than 10 meters from the combustible storage point;

9. Anti-corrosion: The storage point of compressed gas cylinders should be far away from strong oxidizing and corrosive substances, and fire-fighting equipment should be set up at 3-5 meters from the storage point.
