为了防止铅浴炉铅液的氧化和减少铅蒸气的挥发,一般都采用在铅液表面放置一层粒状木炭,但实践证明,木炭防氧化效果不佳,铅蒸气挥发也较为严重。例如,一台坩埚直径950毫米的铅浴炉每年氧化的铅达两吨多,并且木炭消耗量也极大。为解决这一问题,我们采用了盐浴防氧化保护的方 In order to prevent the oxidation of the lead bath lead liquid and reduce the volatilization of the lead vapor, a layer of granular charcoal is usually placed on the surface of the lead liquid. However, it has been proved that the oxidation prevention effect of charcoal is poor and the lead vapor volatilization is also more serious. For example, a 950 ° C lead-fired furnace with a crucible has more than two tons of lead per year and consumes very much charcoal. To solve this problem, we use a salt bath anti-oxidant protection side
