摘要
介绍国电河北龙山发电有限责任公司2号锅炉和沧州华润热电有限公司1号锅炉立柱的分层类缺陷,分析分层类缺陷产生的原因与危害,提出避免分层类缺陷漏检的检验方法。通过分析分层类缺陷钢板的平行夹层面积、夹层与板面角度及夹层位置对钢结构安全性的影响,认为分层类缺陷在4种情况时必须进行处理。
Lamination defect of Guohua Hebei Longshan Electric Power Ltd. Company No. 2 boiler and Cangzhou Huarun Thermal Power Company No. 1 boiler column are presented, causes and harm of lamination defect are analyzed, then, the examining method avoiding undetected lamination are advanced. Through analysis on the influence of parallel interlayer area, angle between interlayer area and board-surface, interlayer area position on steel structure safety, the conclusion is received that it should be treated while four kinds of instance.
