HX_2—30型电弧炉电极松紧缸的进液管经常发生“打火”现象,有时一个班发生几次,严重影响冶炼的正常进行。伴随而来的是漏液和进液管密封圈水解,由于漏液污染引起横臂绝缘破坏,导致横臂与立柱连接“打火”。 我们分析了“打火”的原因,主要是液压缸和进液管连接处连接法兰的绝缘和密封设计的可靠度不够。如图1所示,连接法兰 HX_2-30 type EAF electrode elastic cylinder inlet pipe often “hit the fire” phenomenon, sometimes several times a class, seriously affecting the normal smelting. Accompanying is the leakage and inlet pipe seal hydrolysis, due to liquid leakage caused by crossbar insulation damage, leading to cross-arm and column connection “sparking.” We analyzed the causes of “sparking”, notably the lack of reliability of the insulation and seal design of the connecting flange at the cylinder and inlet connections. As shown in Figure 1, connect the flange
