As the blood of Industry , Nitrogen & Hydrogen play a big role in this field . They used for cold rolls production, stainless steel, with galvanization line, silicon steel , high-carbon steel, cooper productions (brass, red cooper, cupronickel )etc . Nitrogen & hydrogen usually worked with different kinds of furnace such as Bell type furnace, continuous bright annealing furnace。
Gas in Steel & Cooper industry features：
● Purity : normally using mixing gas
Nitrogen purity : 99.999%
Hydrogen : 99.99%
Hydrogen and nitrogen mixing gas rate :
H2 : 5%-50%
N2 : 50%-95%
● Pressure : 1-5 bar(G)
● Dew point : ＜-60℃
● Backup system will be mandatory, prefer Nitrogen plant working + Liquid nitrogen system backup mode or Nitrogen plant working + High pressure nitrogen plant storage (pressurize )standby type
● System interlocking control & fully automatic
Typical reference : BAO STEEL, ANSTEEL, JYXC,, BSB STEEL, GUNUNG Steel etc
