在热处理工作中,一般鹽浴剂都采用含78％或45％氯化钡的混合鹽。使用氯化钠(精盐)作盐浴剂还不广泛,甚至有些人对它的性能有怀疑。根据我们使用的经验,用氯化钠作盐浴剂,不论在使用方面或是节约方面,都有很好的效果。现在把我们的使用经验介绍出来,供大家参考。一、氯化钠性能氯化钡盐(包括含78％或45％两种)的使用温度虽然很广,可以达670～900℃;但它容易陈化,使用期限不长,在800℃以上使用,会发生脱碳或分解,并且有使工件受腐蚀和剥离不好的现象。这种盐更不宜用来作快速加热或合金钢加热。改用100％氯化钠(或95％氯化纳加5％碳酸纳)作盐浴剂,
In the heat treatment work, the general salt bath agent used mixed salt containing 78% or 45% barium chloride. The use of sodium chloride (salt) as a salt bath agent is not extensive, and even some people have doubts about its performance. Based on the experience we use, using sodium chloride as a salt bath agent has good results both in terms of usage and conservation. Now introduce our experience, for your reference. First, the performance of sodium chloride Barium chloride (including both 78% or 45%) of the use of temperature is very wide, up to 670 ~ 900 ℃; but it is easy to aging, the use of the period is not long, above 800 ℃ Use, decarburization or decomposition occurs, and the workpiece is subject to corrosion and peeling is not good phenomenon. This salt should not be used for rapid heating or alloy steel heating. Use 100% sodium chloride (or 95% sodium chloride plus 5% sodium carbonate) for salt bath agent,
