摘要：酸性介质离心压缩机机壳风筒内壁镶嵌防腐衬板能有效提升机组的耐腐蚀性。通过梳理离心压缩机风筒内壁镶嵌小尺寸防腐衬板工艺方法及3 mm衬板单件加工存在的实际问题，分析传统工艺方案所造成的防腐衬板“鼓包”问题原因。以有限元理论为基础，运用切削力原理和静力学分析方法，计算传统工艺方案和一次加工成型方案中不同厚度衬板单件加工最大理论变形量，将理论变形量进行对比分析，优化并制定风筒内壁镶嵌小尺寸防腐衬板的工艺方案，同时将传统工艺方案和优化后工艺方案进行制造成本对比，并对优化后工艺方案进行实际加工验证。该研究为小尺寸防腐衬板的加工提供了理论依据，同时为解决防腐衬板“鼓包”问题奠定实践基础。

Abstract：The application of inlaid anti-corrosion lining plate on the inner wall of air duct of the acid medium centrifugal compressor can effectively improve the corrosion resistance of the unit. The process method of and the actual problems existing in the processing of single piece of 3mm lining plate were reviewed. The causes of the “bulge” problem for the lining plate caused by traditional process method were analyzed. The cutting force principle and the static mechanics analysis method were used to calculate the maximum theoretical deformation for single piece of lining plate in both traditional process and single process forming based on the finite element theory. The process program was optimized and formulated by the comparative analysis of theoretical deformation. The manufacturing cost was compared between the traditional process method and the optimized process method, and the optimized process method was verified by actual processing. The theoretical basis for the processing of small-size anti-corrosion lining plate can be provided, which lays the practical foundation for solving the problem of “bugle” of anti-corrosion lining plate.
