由江苏省靖江合金电极厂试制的RDMZ型埋入式主电极快速启动盐浴炉于1989年7月10在南京市通过省级鉴定。鉴定会由江苏省机械工业厅主持,江苏省热处理分会理事长周建初教授任鉴定委员会主任委员,有来自各地的20位专家、教授、高级工程师出席。 RDMZ型埋入式电极快速启动盐浴炉技术是机电部兰州石油机械研究所的一项获国家三等发明奖科技成果,该炉体结构新颖,电极为多层马蹄状,启动时先将电极与变压器联接,通电后变压器输出的低电压大电流流入电极。电极很快发热,使其附近的凝盐熔化,此时主电极起着辅助电极作用,一俟电极
RDMZ embedded main electrode rapid start salt bath furnace trial-produced by Jiangsu Jingjiang Alloy Electrode Factory passed the provincial appraisal in Nanjing on July 10, 1989. Identification will be chaired by the Jiangsu Provincial Bureau of Machinery Industry, Jiangsu Province, Professor Zhou Jianchu, chairman of the branch of heat treatment appraisal committee chairman, with 20 experts from around the professors, senior engineers attended. RDMZ embedded electrode rapid start salt bath furnace technology is the Electrical and Mechanical Engineering Lanzhou Institute of Petroleum Machinery won a third prize of national scientific and technological achievements, the novel structure of the furnace, the electrode is multi-layer horseshoe-shaped, start the first electrode Connected with the transformer, the low voltage and high current output by the transformer will flow into the electrode after power on. The electrode heats up very quickly, causing the condensed salt near it to melt. At this time, the main electrode functions as an auxiliary electrode, and the electrode
