炼钢电弧炉采用水冷炉壁技术之后,炉壁寿命大幅度提高,一般报道,水冷炉壁的连续寿命都在千炉以上。我厂的水冷炉壁从79年3月运行以来,其连续寿命最高也已达到1900炉,目前仍在继续使用。但是,由于渣线和炉底侵蚀厉害,影响了电弧炉整体寿命的提高。从表1可知,我厂各电炉安装水冷炉壁以后,炉龄都有不同程度的提高,但 Steel-making electric arc furnace using water-cooled furnace wall technology, the furnace wall greatly increased life expectancy, generally reported that the continuous life of water-cooled furnace wall in more than one thousand furnaces. Since our factory’s water-cooled furnace wall has been operating since March 79, its continuous life expectancy has reached 1900 furnaces and is still in use. However, due to the strong erosion of the slag line and the bottom of the furnace, the overall life of the electric arc furnace is affected. As can be seen from Table 1, after the installation of water-cooled furnace wall in each electric furnace of our factory, the furnace ages have different degrees of improvement,
