我厂自生产φ200、φ250毫米三爪卡盘以来,盘丝淬火一直是用碱液处理。碱液处理对我厂来说,氢氧化钾不但是价格昂贵,而最大的困难是来源缺乏,往往因短缺而影响生产。其次,熔化需耗电,使用易老化不易回收,成本高。第三,劳动条件差,易损伤皮肤。因此,寻找新的淬火介质代替碱液将成为我们生产急待解决的问题。 I plant since the production φ200, φ250 mm three-jaw chuck since the coil wire quenching has been treated with lye. Lye treatment For our plant, potassium hydroxide is not only expensive, but the biggest difficulty is the lack of sources, often due to shortage and affect the production. Second, the melting needs power consumption, the use of easy aging is not easy to recover, high cost. Third, poor working conditions, easy to damage the skin. Therefore, looking for new quenchant instead of lye will become an urgent problem for our production.
