The cryogenic reservoir consists of two reservoirs, the main reservoir being placed inside an outer crust, and between these two reservoirs, there are insulating materials such as perlite acting on the basis of a molecular sieve. The inner reservoir of the inner tube of the reservoir is It is a stainless steel which, along with many tests carried out on the reservoir, ensures the quality and quality of gas liquids, which is an important factor in maintaining the purity of the gas above these reservoirs using advanced techniques and technology of the world. Which is made under the quality control system. Several items in the design and construction of these tanks And advanced equipment around the world. Cryogenic tanks in the steel industry have many applications, including reservoirs: liquid oxygen nitrogen, argon liquids, co2. Tanks used in steel complexes are usually of high capacity and work pressure 5 to 15 times. The method of recharging the reservoirs in steel sets is in two ways: 1. Using the box box: In this method, the box box separates oxygen and nitrogen from air separation and … using From the vacuum jacket to the tank. 2. Using the tankers (toxic trailer): In this method, the gas in the mercury No longer produced and used tanks to the main tank will Atnqal.

TECHNICAL INFORMATION

The use of gas in the steel production process is widespread, and in this section oxygen gases, nitrogen and argon are each used for a certain activity. A brief explanation of the use of these gases is presented:

1-Oxygen: One of the methods of smelting and refining iron ore is to add to the amount of recycled steel. The two are combined in the oxygen furnace. In the furnace, pure oxygen (99.5) is blown to this compound with ultrasonic velocity. This amount of oxygen is combined with carbon and silicon in the furnace, causing a lot of heat to be added to the steel as a result. In this process, iron oxide, manganese and phosphorus oxidation also produce heat. The carbon monoxide produced by the burning out of the furnace also brings its heat to the furnace. The difference with the arc method is that it does not require external energy to progress. The output of this molten iron furnace has specific chemical properties at 2 900 Fahrenheit (1 590 C) to 3,000 Fahrenheit (1,650 Celsius), which is further refined. The basic word refers to magnesium oxide MgO, which is refractory material and does not combine with the slag produced in the furnace and can be used for thermal insulation in the furnace

2-Nitrogen: The addition of nitrogen increases the ductility and stiffness and thus eliminates the need to return after warm work. Adding nitrogen to 20% Cr and 27% Cr, which is common practice, and naturally have a completely ferritic structure and exhibit resistance to grain growth during heating up to high temperatures. Adding nitrogen to these steels amounts to It creates a little austenite and a secondary phase in the microstructure that can be used to heat without any risk of grain growth, and also their hot work is easy. Usually the percentage of nitrogen added is about one hundredth of a percent chromium, since it is almost the most The percentage of nitrogen that can be present in a solid solution. Nitrogen also benefits from steel making. Ned. Nitrogen gas is considered by the industry as a cleaning gas. Other uses of nitrogen in this industry are copper oxide and play the role of protective gas for welding. This gas is used to create inert atmosphere in the casting of steel and other molten metals.

3-Argon: When steel is produced, oxygen and argon gas are blown into molten metal. The excess amount of argon gas reduces the amount of chrome lost and optimizes the contents of the desired carbon at a lower temperature. Argon gas is used as a blower gas during the production of high grade steel to prevent the formation of nitrides. . It is also used as a neutral gas for casting. Argon gas is used in aluminum to help dissolve to remove hydrogen and particles from molten aluminum. Argon gas is used as a neutral gas in the production of titanium to prevent oxidation and reaction with nitrogen gas (titanium is the only metal that burns in the atmosphere at 100% nitrogen).

Selecting the tank

In choosing cryogenic tanks, the following points should be considered.

-Development Scheme: Due to the fact that cryogenic tanks are 40 years old, it is better to consider at least the development plan for the next 5 years.

-Installation location: In companies, it should be checked to see if there is a possibility to install the oxygen tank in this area! Is the position suitable for installation of the crane! And so on

– The position of the tank for charging with transporting tankers or through the cold box should be checked.

If the tanks are used for storage, the discharge conditions should also be considered.

If liquid nitrogen tanks are used for emergency situations, the tank position is very strategic.
