提高炉温均匀性的措施电炉炉温的准确性是保证机械零件热处理工艺质量的重要条件，我国《ＪＢ３８７７－８５钢的淬火回火处理》标准指出，特殊重要零件热处理时，有效加热区的温差允许值为±１０℃，而在我国许多陈旧的ＲＪＸ型箱式电阻炉中，炉膛各区间温差悬殊，最高可... Measures to improve the uniformity of furnace temperature Furnace temperature accuracy is to ensure the quality of mechanical parts heat treatment process an important condition, China’s “JB3877-85 steel quenching and tempering” standard points out that the special important parts of the heat treatment, the effective heating zone temperature difference Allowable value of ± 10 ℃, and in many of our old RJX box-type resistance furnace, the temperature difference between the various sections of the furnace, the highest ...
