摘要
8 4 0 0 mm大型焦炭塔的设计为国内首次 ,其主体材质选用 Cr-Mo钢 ,焦炭塔上部泡沫段选用不锈钢复合钢板 ;裙座与筒体连接采用对接堆焊的型式并在裙座上开设膨胀缝。针对焦炭塔操作时低频疲劳容易引起筒体变形和焊缝开裂的问题 ,采取了多项改进措施。
The design of φ8400mm large scale coke drum is the first in domestic.The material of Cr Mo steel is selected for main shell,and stainless steel clad plate is selected for upper foam section of coke drum.The joints between skirt and shell are the butt surfacing welding type,and expansion joints are provided in the skirt.In accordauce with the problems of shell deformation and welding crack caused by low frequency fatigue during coke drum operation,some improvements are adopted.
