摘要
文章介绍了 4 0 0m3 氮气球罐制作、安装过程中的重要工序———焊后热处理 ,从理论、退火工艺、实际操作、退火效果等方面对球罐的焊后热处理工艺进行了深刻的剖析。实践表明 ,该球罐焊后热处理的处理工艺和实施方案是可行、正确的。
Heat-treatment after welding, an important step in the process of fabrication and installation of 400m3 nitrogen sphere tank, is introduced here. For this, many inspects, such as the theory, annealing, actual operation, annealing effects and so on, are deeply analyzed. It is, through practice, proved that the process of heat-treatment and the plan of putting it into practice are feasible and correct.
