我厂热处理盐浴炉在运行过程中，往往因铁电极生热而引起变压器被烧坏，此缺陷夏季尤为突出。分析原因，一是铁铜电极接触点发热；二是汇流排导热；三是电极与炉膛的参数不匹配。其核心是因电极发热而传导给变压器。由此分析，我们认为应把避免铁电极发热放在首位来处理。于是 I plant heat treatment salt bath furnace in the operation process, often due to fever caused by the iron electrode transformer is burned, this defect is particularly prominent in summer. Analysis of the reasons, one iron and copper electrode contact point fever; second busbar heat; third electrode and the furnace parameters do not match. Its core is because the electrode heat conduction to the transformer. From this analysis, we believe that should avoid the iron electrode fever in the first place to deal with. then
