自1952年奥地利发明氧气顶吹炉炼钢法(LD 法)后,世界钢铁工业进入了一个大飞跃。今天,氧与钢已紧密地联在一起,钢铁工业仍然是制氧机的大用户。据日本神钢介绍,转炉吨钢耗氧50～60米~3(1984年日本平均为52.3米~3/吨,1985年日本平均为52.7米~3/吨),电炉吨钢耗氧10～25米~3、平炉吨钢耗氧20～40米~3、高炉吨铁耗氧49～63米~3(富氧率3%),轧钢吨钢耗氧3～6米~3。此外,在钢材加工、废钢切割、加热等用氧,每吨钢约需11.4～
Since the invention of the oxygen top blowing furnace (LD) method in Austria in 1952, the world steel industry has taken a big leap forward. Today, oxygen and steel are closely linked, and the steel industry is still the major user of oxygen generators. According to Japan’s Kobelco introduction, oxygen consumption per ton of steel converter 50 ~ 60 m ~ 3 (1984 Japan average of 52.3 m ~ 3 / t, Japan in 1985 an average of 52.7 m ~ 3 / t), electric furnace steel consumption of oxygen 10 ~ 25 m ~ 3, open hearth steel consumption of oxygen 20 ~ 40 m ~ 3, blast furnace tons of iron consumption of oxygen 49 ~ 63 m ~ 3 (oxygen rate of 3%), steel rolling steel oxygen consumption 3 ~ 6 m ~ In addition, steel processing, scrap cutting, heating and other oxygen, about 11.4 ~ per ton of steel
