摘要
分析Cr-Mo钢焦炭塔的特点和技术进展,指出焦炭塔发生开裂的主要原因是热机械疲劳造成的;针对Cr-Mo钢焦炭塔的焊接特点,从焊接材料选择、焊接返修工艺和焊后热处理等方面分析焦炭塔的焊接返修技术,给出了具体的返修工艺,并对回火焊道技术的应用进行了探讨。
The future technique proceedings of Cr - Mo steel coke drum have been described. The crack on Cr - Mo steel coke drum is due to heat-mechanical fatigue. Based on welding performance of C - Mo steel coke drum, the repair welding procedure of coke drum have detailed, deal with the select of welding materiel,the parameters of welding repair, and PWHT. Finally the temper bead welding technology had been discussed.
