一、概述盐浴炉具有加热速度快、氧化脱碳少、温度均匀、结构简单、操作方便、生产效率高等优点,当今仍为热处理行业广泛采用。盐浴炉所采用的加热介质,通常是 KCl,NaCl 以及 BaCl_2等氯化盐。这类盐皆属离子键化合物。在熔融状态下,离子活动能力增强,在外电场作用下,离子定向流动,使熔盐具有导电性。此时熔盐电阻仅为0.003～
First, an overview Salt bath furnace with heating speed, oxidation and decarburization less, uniform temperature, simple structure, easy operation, high production efficiency, is still widely used in heat treatment industry today. Salt bath furnace heating medium used, usually KCl, NaCl and BaCl_2 chloride salts. Such salts are ionic bond compounds. In the molten state, the ion activity increased, under the action of an external electric field, ion-oriented flow, the molten salt has conductivity. Molten salt resistance at this time is only 0.003 ~
