法国SME直流电弧炉所使用的水冷炉底电极是由一根水冷铜管组成,其类似于连铸机的水冷结晶器来提供冷却作用,绝缘保护外套隔绝铜管与铜管内起导电作用的钢棒。这种设计还包括一个补偿器,它能够较好地避免装入废钢时对炉底电极的冲撞。 炉底电极的更换可通过几种途径来完成。较理想的方法是更换整个炉底,可减少停工时间,但至少需要8小时才能完成。另一种方法是更换夹持炉底电极的炉底平台,这种方法要求使用钢包车,其安装有液压系统,可以操作炉底平台的设备,这种方法约4小时才能完成,且要求炉子冷却后方可移开炉底,其时间较长。
France SME DC EAF water-cooled bottom electrode is used by a water-cooled copper tube, which is similar to the continuous casting machine water-cooled crystallizer to provide cooling effect, the insulation protection of the outer jacket and copper copper tube conductive role Steel bars. The design also includes a compensator that better protects the bottom electrode from loading when scrap is loaded. Bottom electrode replacement can be accomplished in several ways. The better way is to change the entire furnace floor to reduce downtime, but it will take at least 8 hours to complete. Another method is to replace the bottom plate holding the bottom electrode. This method requires the use of a chartered van equipped with a hydraulic system that can operate the bottom plateau. This method takes about 4 hours to complete and requires that the furnace After cooling, the bottom of the furnace should be removed for a long time.
