6、···················153#转炉LF炉及转炉二次排烟罩钢结构制作安装施工方案22一、概述新增建LF炉主体分布在14～15轴、E～F跨，我单位主要承建LF炉低层钢结构的制作及安装，主体结构为▽5.9m平台钢结构系统，A版次施工图中增加喂丝机平台，及除尘系统管道支托架，除平台板及隔热板为板式结构外，其它构件以H型钢为主体。转炉炉口二次排烟装置为炉前上方排烟系统，以板式结构为主体。在冬季施工期间及寒冷天气施工，仍以《3#转炉主厂房（钢结构冬季施工）》方案主指导从3#转炉全局施工来看，安装时必将是多个施工队在

7、此穿插，结合现场和施工特点来看该工程有：1.1工程重点及难点为：1.1.1场地狭小，施工平面布置困难。1.1.2施工多为高空作业，安全问题较为突出。1.1.3二次排烟罩的安装为收尾接近烘炉调试期估计将是多施工队、多专业穿插施工二、编制依据2.1《通钢炼轧厂增建3#转炉工程3号LF精炼系统钢结构》施工图，图号：072.15C30601J131；2.2《转炉炉口二次排烟装置》施工图，图号：DG3615；2.3《钢结构工程施工质量验收规范》（GB50205—2001）；2.4《建筑钢结构焊接技术规程》（JGJ81-2020）

8、；2.5《钢结构施工手册》三、施工程序及方法3.1材料进场验收：3.1.2原材料——供应部门按时、按要求将钢材采购到货后，及时通知我方运送到制作场地，原材料采购品种和数量与计划相符，质量保证书要与钢材的标识相符，每批到场的钢材必须具有22生产厂提供的材质证明书，证明书上各项数据齐全。我方按规范对进场材料数量、外观及外形尺寸进行复查
