我厂1.5吨电弧炼钢炉是西安电炉厂成套供应的。其导电铜管与电极夹持器之间原系法兰连接(如图1),使用中发现这种连接有以下缺点:金属密封垫片裸露,在高温及腐蚀性气体的作用下,容易产生氧化剥落,进而起弧烧损,造成漏水。遇到这种情况就得冒高温抢修,也常因此停炉,并严重影响钢水质量。 I plant 1.5 tons arc furnace is a complete set of Xi’an Electric Furnace supply. The conductive copper tube and the electrode holder between the original flange connection (Figure 1), the use of this connection found the following disadvantages: Metal gasket exposed, in the high temperature and corrosive gases, prone to Oxide spalling, and then start burning loss, resulting in water leakage. In such cases have to take high-temperature repair, often so shutdown, and seriously affect the quality of molten steel.
