- 摘要:
- 石油化工设备在制造过程中,由于受到冷、热变形、弯曲、冲击及焊接等作用,其材料和结构内部会产生较大的残留应力。文中重点叙述了低温设备内残留应力的危害,低温设备热处理的方法、工艺和加热温度的确定。
In the course of manafacture of petrochemical equipment,the are less big residual stress in in- terior of the structure and material because of cold and hot deformation,bending,impact,welding and so on.This article discusses the damage of interior residual stress to the low temperature equipment and heat treatment technology for the low temperature equipment.1993,2(2): 12-15 收稿日期:1992-5-8参考文献:
