首先谈谈什么是碱浴的老化。我们认为,当碱槽底部出现大量沉积物、碱浴熔点升高、流动性降低、表面结壳硬化时就已老化。当碱浴老化后冷却性能变坏,会导致工件淬火后不能满足技术要求,甚至引起工件报废。直接影响产品质量的提高。碱浴老化的原因是什么呢?根据我厂近十年的经验,我们认为碱浴老化的主要原因是碱液中各种杂质(如:K_2CO_3、Na_2CO_3、KCl、NaCl、FeO、
First talk about what is the aging of the alkaline bath. In our opinion, when a large amount of sediment appears at the bottom of the caustic tank, the melting point of the caustic bath increases, the fluidity decreases, and the surface crust has aged when it is hardened. When the alkali bath aging deterioration of cooling performance will lead to quenching the workpiece can not meet the technical requirements, and even lead to scrapped parts. Directly affect the improvement of product quality. According to the experience of our factory for nearly ten years, we think that the main reason of alkali bath aging is all kinds of impurities (such as K 2 CO 3, Na 2 CO 3, KCl, NaCl, FeO,
