酒钢7号高炉炉底封板裂缝检修工艺及维修处理方案

本文通过介绍酒钢7号高炉炉体检修中炉底封板裂缝现场检修工艺及处理自编方案,针对现场遇到的裂缝问题,分析其产生的原因并做出检修工艺和现场维修方案,通过对焊缝打磨,贴补板条拉筋板并焊接固定,灌浆处理等一系列技术措施,避免了微观裂纹、锈蚀彻底清理难度大、焊接清理难度大、耗时长等因素,提高了焊接生产率,且焊缝成型美观,质量优良,取得了较好的效果。从而达到提高质量、缩短工期、确保安全、增进综合经济效益的效果。

The Maintenance Processes and Plans about Repairing Sealing Plate Crack of JISCO 7# Blast Furnace Bottom

Some maintenance processes and self-designed plans on how to manage furnace bottom sealing plate crack of JIS-CO 7# blast furnace is introduced.The crack problems encountered at the scene was solved, the causes was analyzed and the maintenance process plan was made. By using the weld grinding, slab reinforcement plate and fixed welding, a series of technical measures of grouting treatment and so on, these factors like micro cracks, corrosion cleaning difficult and time consuming were avoided. By this way, the factory improves their welding productivity, weld appearance, excellent quality and eventually achieves good results. The technology contributes to improving the quality, shortening the period of time, en-suring the safety and creating comprehensive economic benefits.
