摘要： Undesired nitrites are formed during the treatment of salt bath nitrided structural components of iron and steel in nitrate containing cooling baths, and they must be removed from the washing water. The build-up of nitrites can be avoided by oxidizing the nitrite in the salt bath into nitrate by passing air into the cooling bath during off-times.

摘要： Waste waters from salt bath hardening and galvanizing operations are removed through evaporation of the injurious material containing waste water and complete detoxification of the concentrate from the evaporation. The waste waters are first brought to a salt content of 300-500 grams/liter and this concentrated solution is then supplied to a molten salt bath.

摘要： Low cyanide nitriding salt baths which are composed of alkali cyanate and alkali carbonate and used for treating components made of steel and iron produce coatings on the surface of the component in some cases and can lead to problems in the use of the components. A satisfactory surface quality can be obtained from nitriding salt baths which additionally contain 0.5 to 100 ppm of selenium.
摘要翻译： 由碱金属氰酸盐和碱金属碳酸盐组成的用于处理由钢铁制成的组分的低氰化氮化盐浴在一些情况下在组分的表面上产生涂层并且可能导致使用组分的问题。 从含有0.5〜100ppm硒的氮化盐浴可获得令人满意的表面质量。
