1.存在的问题及改进方法 我公司10t全液压炼钢电炉,采用整体水冷炉盖。炉盖重达3650kg,其最大直径为φ3700mm,最大高度为730mm,由厚度为12～16mm的A3钢板和锅炉钢板焊接制成。炉盖中间等距离三个电极孔的最大偏差≤±5mm,试验水压0。6MPa(6kgf/cm~2)。 在炼钢生产中发现,炉盖电极孔侧壁或下部焊缝经常漏水,必须对其进行维修,从而增加了热停时间,直接影响了生产。 为解决此弊,我们对原炉盖先后进行了5次改进。利用废旧炉盖,将其受热严重、
1 existing problems and ways to improve my company 10t full hydraulic steelmaking electric furnace, using the overall water-cooled furnace cover. Cover weighing 3650kg, the maximum diameter of φ3700mm, the maximum height of 730mm, the thickness of 12 ~ 16mm A3 steel and boiler plate welded together. The maximum deviation of the three electrode holes equidistant from the middle of the furnace cover is less than or equal to ± 5mm and the test water pressure is 0.6MPa (6kgf / cm ~ 2). Found in the steelmaking production, the lid electrode hole side or bottom of the weld often leaks, it must be repaired, thereby increasing the heat stop time, a direct impact on the production. In order to solve this problem, we made 5 improvements to the original furnace cover successively. The use of waste lid, it will be heated seriously,
