text-align: center;"><span style="font-size: 18px;"> <span style="font-size: 15px;"></span></span></p><p style="line-height: 2em; text-align: center;"><span style="font-size: 18px;"> <span style="font-size: 14px;">一双“铁臂”可吊2200吨钢箱梁</span></span></p><p style="line-height: 2em;"><span style="font-size: 18px;"> </span></p><p style="line-height: 2em;"><span style="font-size: 18px;"> 该船由武桥重工武汉总部设计，珠海基地建造，深圳船厂总装后下水调试。这个拥有两幅“L”型臂架的起重船，单幅臂架重量约700吨，一次可吊起重达2200吨的钢箱梁。为让这两只“铁臂”既有力量，又方便运输、安装，臂架采用Q690高强度钢板焊接成箱型梁，并采用栓焊可拆式桁架结构，在国内大型起重设备中尚属首次。</span></p><p style="line-height: 2em;"><span style="font-size: 18px;"> </span></p><p style="line-height: 2em;"><span style="font-size: 18px;"> 许建耀说，Q690最大屈服强度690兆帕，是目前国内最优质的高强度钢板，但对焊接工艺要求非常高，大规模应用于重型起重机臂架国内少见。“为了保证焊缝的焊接质量，焊接前需要采用加温装置对焊接区域进行加温，焊接过程中对焊道需严格控制温度，焊接完成后保温，待自然冷却48小时后进行无损检测。”</span></p><p style="line-height: 2em;"><span style="font-size: 18px;"><br/></span></p><p style="line-height: 2em;
