活塞环撑簧发蓝流水线工艺研究

A RESEARCH ON THE BATCH PROCESS OF BLUE ING THE EXPANDING SPRING IN PISTON RING

１９９３～１９９４年，对长沙正圆动力配件厂活塞环撑簧发蓝生产线进行了大规模技术改进，采用新工艺新配方后，较好地解决了弹簧表面氧化膜质量与大批量生产之间的矛盾，为工厂创造了可观的经济效益．

During 1993 and 1994,in the technical improvement of the production line of blueing the expanding spring in piston ring,a new technology and prescription were utilized,which resolved the problems of the surface oxidation quality of the springs in batch process.
