氮气是一种中性气体,取自于大自然,对环境友好,是绿色、环保资源。在化学热处理中,氮基气氛是以氮气为基本成分并加入适量的添加剂(如甲醇等)制备而成(一般在炉内直接生成)的一种可控热处理气氛。氮基气氛具有气源丰富、节约能源、成本低廉、安全性好、适应性强、污染少等优点。因此,在工业发达的国家得到迅速发展。近年来随着制氮技术的进步,氮基气氛热处理技术已在我国推广应用,并有取代传统的吸热式气
Nitrogen is a neutral gas, taken from nature, environmentally friendly, is a green, environmentally friendly resources. In chemical heat treatment, the nitrogen-based atmosphere is a controllable heat treatment atmosphere which is prepared by using nitrogen as a basic component and adding an appropriate amount of additives (such as methanol and the like), which is usually directly generated in a furnace. The nitrogen-based atmosphere has the advantages of rich gas source, energy saving, low cost, good safety, strong adaptability and less pollution. Therefore, rapid development has taken place in industrially developed countries. In recent years, with the progress of nitrogen production technology, nitrogen-based atmosphere heat treatment technology has been applied in our country, and replace the traditional endothermic gas
