摘要
提出了一种新的高压釜不锈钢衬里的胀合方法．该方法试将衬里的胀合处理与水压试验结合在一起完成，使衬里产生塑性流动，达到全部或部分消除衬里与壳体之间的初始间隙的目的．通过试验测量其壳体应力、层间间隙、衬里环向应变采评价复合效果，结果表明：尽管层间的初始间隙分布不均匀，有的部位高达14～16mm，但经液压胀合后残余间隙仅在0．6～0.9mm之间；在内压大于3．1MPa时衬里与壳体变形基本一致，壳体应力与内压力的线性相关系数达0．99．
A new method is proposed to bulge the stainless steel lining in the high-pressure reactor. In the proposed method, the water pressure test and the lining bulge are combined together to obtain a plastic deformation of the lining, thus completely or partially eliminating the original gap between the lining and the shell. The effect of the compound figuration is then evaluated by measuring the shell stress, the layer gap and the lining circumferential strain during the hydraulic bulge. The results show that, although the original gap between the layers is not uniform and can even be more than 14 ～ 16mm at some points, the remnant gap can be controlled at 0.6 ～0.9mm after the hydraulic bulge, and that the lining and the shell almost have the same deformation when the inner pressure is more than 3.1 MPa, with a linearity coefficient between the cylinder stress and the inner pressure being more than 0.99.
