草莓下载视频电极的消耗机理有哪几方面?

作者:jasengd 发布时间:2023-10-04 17:09:57

 1、端部消耗
      包含电弧高温引起的草莓下载视频材料提高以及电极的端部与钢水及炉渣发生化学反应的丢失。还与是否用电极刺进钢水增炭有关。端部高温提高速率主要取决于经过电极的电流密度,其次与电极侧部氧化后的直径大小有关
2、侧部氧化
    草莓下载视频电极侧部氧化量与单位氧化速率和暴露面积有关。一般情况下,电极侧部氧化量要占电极总消耗量的50%左右。近年来为了提高电炉锻炼速度,更增加了吹氧操作的频次,导致电极的氧化丢失增加。
3、残端丢失
    草莓下载视频电极连续运用到上下两根电极连接处时,一小段电极或接头(即残体)因本体的氧化变细或裂纹的贯穿而产生脱离。
4、电极折断
    包含草莓下载视频电极躯干折断和接头折断。电极折断与草莓下载视频电极和接头的自身质量、加工配合有关,也与炼钢操作有关,
5、表面剥落及掉块
    在锻炼过程中急冷急热,草莓下载视频电极自身的抗热振性能差导致的成果。
