3.1.2 Furnaces:
3.1.2 冶金炉：
3.1.2.1 Heating Media: Shall be air, protective atmosphere, combusted gas, molten salt bath, oil bath, of fluidized bed. Electrical heating elements and radiant tubes shall be shielded to prevent direct radiation from striking any part. The products of combustion in the furnace, and the composition and maintenance of salt baths and fluidized beds shall be such as to prevent attack or contamination of the parts. Ammonium fluoroborate, or equivalent, may be ud in air furnaces as necessary. Nitrate salt baths shall not be ud to heat treat 520.0 alloy due to a potential explosion safety hazard.
3.1.2.1 加热介质：应该为空气，保护性气氛，燃烧气体，熔融盐槽，油槽，流化床。电子加热成分和辐射管应屏蔽，以防止直接辐射。冶金炉中燃烧的产品，和盐池和流化床中的成分应防止零件腐蚀和污染。必要时在空气炉中可使用氟硼酸铵或同类产品。硝酸盐槽应用于520.0合金的热处理，因为可能影响安全的爆炸。
