可再生氰酸盐盐浴在手用钢锯条生产中的应用

可再生液体碳氮共渗新工艺，已在锯条行业推广应用了三年，在其锯条质量、工艺操作、新旧工艺衔接、降低成本、治理环境污染等方面均获成功．目前新工艺在国内生产的锯条每年已达８．８亿支．生产结果证明：新工艺可完全取代原有的传统氰化钠盐浴和尿素盐浴工艺，具有渗速快、硬度高、锯切性能好、节约能源、渗层均匀、碳氮浓度容易控制等优点．

A study on producing hand-saw with liquid carboni- triding process of regenerating cyanite salt bath

A new process for regenerating carbonitriding salt bath proposed has been applied to the hand-saw manufacture for more than 3 years, which has been seccessful in many aspects: the quality of hand-saw, reduction of cost, the practical operation, dovetailing the substitution of new salt bath for old, abating environmental pollution and so on . So far the existing production capacity by the process has amounted to about 880 million pieces of hand-saw. Above mentioned facts have proved that this new process can take place of the traditional cyanide salt bath and the urea salt bath.It denoted that this process has many advantages, such as speedy carbonitriding, super hardness, cutting performance, without poisonous gas, homogeneous case, easy contrllable and adjustable density of carbon and nitrogen.
