前言 氨气经完全分解、净化和干燥后成为含有75％H_2和25％N_2的混合气体,其露点为-40℃～-60℃。它比空气轻2/3,导热性大4倍。 它与纯氢相似是一样强还原性气体。在冶金工业中常常用来作为钢材热处理的保护气体,通过还原反应可以减少钢中氧化物杂质,提高钢的性能,并能使钢表面光亮。如果在其中加入适量的水蒸气,还能使硅钢片脱炭,从而达到提高硅钢的磁感应强度和降
Introduction Ammonia gas is completely decomposed, purified and dried to a mixed gas containing 75% H 2 and 25% N 2 with a dew point of -40 ° C to -60 ° C. It is 2/3 lighter than air and 4 times more thermally conductive. It is as strong reducing gas as pure hydrogen. In the metallurgical industry, it is often used as a protective gas for the heat treatment of steel. Reducing the oxide impurities in the steel through the reduction reaction can improve the properties of the steel and make the steel surface bright. If you add an appropriate amount of water vapor, but also to off-carbon silicon sheet, so as to improve the magnetic induction of silicon steel and strength
