近来探讨了许多种防止金属氧化和脱碳的加热方法与措施。如在真空下完成加热,在中性气体中、在还原性气体中以及在熔融的盐和金属中加热等。伹是这些方法都有缺陷。在真空中处理,除热设备外有时需要很复杂的附加装置(专用的炉子、泵、冷却装置等)。这种处理不是在所有场合下都可以采用的。我们提出并试验了金属在装有作为吸氧剂的金属钠 Recently, many kinds of heating methods and measures to prevent metal oxidation and decarburization have been explored. Such as heating under vacuum, heating in a neutral gas, in a reducing gas, and in molten salts and metals.伹 These methods are flawed. In vacuum, sometimes complicated extras (special furnaces, pumps, coolers, etc.) are required outside of the heat removal equipment. This treatment is not available on all occasions. We proposed and tested the metal in the presence of sodium as an oxygen absorber
