大型奥氏体不锈钢应变强化真空粉末绝热贮槽轻量化设计
|
摘要
以实际产品设计为例,将大型真空粉末绝热贮槽的传统设计与采用应变强化技术的设计进行比较,得出应变强化技术可实现压力容器的轻量化设计。对于应变强化型大型容器,为了较容易实现内、外筒体的套装,采用多种方法有效地控制了强化后的应变,其中控制原材料的屈服强度是最直接有效且不增加成本的控制强化后应变的方法。
Here,with design of physical product as example,the traditional design of large-sized vacuum powder thermal-insulated tank is compared with the design using the strain-intensified technology,and the comparison shows that the strain-intensified technology may realize lightweight design of pressurized vessel. For the strainintensified type large-sized vessel,in order to facilitate shell-type outer and inner cylinder,several methods are used to effectively control the strain after intensifying,and the method to control the yield strength of raw material is the method which most directly effective controls the strain after intensifying and increases no cost.
