Steel industry

To supply high-purity nitrogen, hydrogen, and nitrogen hydrogen mixed gas to the steel industry for the bright annealing process of stainless steel, high carbon steel, and ordinary strip steel. There are two types of furnaces: continuous annealing furnace and hood type annealing furnace. Gas purity requirements: Nitrogen purity is usually 99.9995%, hydrogen purity is usually 99.999%, and the mixing ratio is: H2 ratio is 5% -50%, N2 ratio is 50% -95%.
