Main power of air-separation industry—steel industry
steel industry is the main power for the development of
air-separation industry which lead air-separation industry into its
golden time.
According to the oxygen consumption of steel industry, during the process in the blast furnace, converter, continuous casting and rolling of the traditional process, the oxygen consumption of per ton steel is about 120 Nm3/h. Every year millions of tons of steel production scale need match air separation plants with the capacity of 15000 Nm3/h, when not in oxygen-enriched blast furnace can be reduced to 10000 Nm3/h. When using COREX puddling technology, electric converter, continuous casting and rolling steel are installed, the capacity of the spare parts required for each million tons of steel shall be increased to 50,000 Nm3/h, which is three to five times to traditional technology.
Background information:
Steel industry is the big customer to air-separation worldwide, accounting for 60%~70% of total amount. 60s~80s of last century, the dramatic development boomed air-separation industry. After Japan introduced oxygen converters, the steel output increased from ten million tons to 100 million ton during ten years, the output of oxygen increased 20 times during 16 years. After a detour, China’s steel industry got back on track in the 1980s and exceeded 100 million tons in 1996. 340 million tons in 2005. China became the largest steel country in the world in 2005 with 340 million tons which was more than the sum of the three, Japan, the United States and Russia. And it is expected to be 620 million tons in 2010, more than the sum total of countries that ranked from 2nd to 21st behind.
From 2001 to 2010, due to the rapid development of national economy and the global manufacturing transferring to China, Chinese steel industry promoted developed rapidly. With the average annual output of 46 million tons of crude steel increased, per million tons of supporting air separation unit 15000 Nm3/h, a single steel, need new air separation unit capacity is 690000 Nm3/h.Thus, the gas industry was booming, and the golden period of Chinese air separation was brought forward.
During this period, Chinese air separation industry has followed the world’s advanced level and improves its competitive power. Both software and hardware facilities are ready for the take-off of the air separation industry.

The application of oxygen, nitrogen and argon in steel industry
Oxygen
The processes of puddling and steel-making need much oxygen.
Oxygen top blowing converter steel-making
Blast furnace rich oxygen blast
Electric furnace steel-making
COREX steel-making
Steel processing, continuous casting flame cutting, cleaning and so on, tonnage oxygen consumption is 10 ~ 12Nm3
Nitrogen
Nitrogen is mainly used in metallurgical works for sealing gas, conveying gas, protecting gas, stirring gas, blowing gas, instrument gas, etc.
At present, the consumption ratio of oxygen and nitrogen in metallurgical plants is about 1:1, and the nitrogen consumption is also increasing. The nitrogen production should be properly reserved on design.
Argon
Argon is used for stainless steel smelting, steel ladle argon lowing, conticaster steel ladle and tundish nozzle sealing, protecting gas, etc.
At present, the energy consumption of argon in metallurgical plants is not very large, about 3 ~ 4.5Nm cubed per ton of steel, usually after the total amount is extracted, spare parts are sold.

The dependence relationship between steel industry and air separation industry
Interdependence and mutual promotion is the relationship between steel
industry and air-separation industry. Growth of steel industry leads the
development of gas industry and the development of gas industry
promotes steel industry, which is similar to the closed acting force and
counter-acting force. New technologies appeared in steel industry
require new quantity, quality and technology from gas industry now and
again. To meet the continuous demands of steel industry, gas industry
has developed itself and promoted the steel industry forward, which can
be noticed when looking back the development of domestic and overseas
air-separation industry. Get a clear understanding of the relationship
between the two industries is extremely important to gas industry, which
can remind us to focus the development trends of steel industry and
make or modify industry development strategies. It also help gas
industry to research new gas technology combined with steel industry to
capture business opportunities and control the market. When the steel
industry flags, a clear understanding can adjust the marketing direction
in time, improve the old air separation plants transformation and reserve technologies.
