我厂生产之活塞环,规格较多,直径大小不一,直到目前我厂生产的空压机活塞环已有20余种。长期以来,由于在生产组织及制造工艺上存在一定问题,产品质量一直不稳定,特别是在金相组织方面,经常出现C、D、E型石墨,造成活塞环脆裂、塑性变形大、硬度不合格等一系列问题。 今年以来,在以提高产品质量为中心的双革运动当中,为迅速提高活塞环质量,解决历年来的质量关键,我们以三结合的组织形式,采取打歼灭战的方法,组织攻关。为了摸透情况,查明原因,我们认为,必须深入实际,到实践中发现问题,从而解决问题。从多次的浇注中,我们重点加强了各部门之间的联系,尤其是配料、熔化及浇注等
I plant the production of piston rings, more specifications, the diameter of different sizes, until now I plant the air compressor piston ring has more than 20 species. For a long time, due to the production organization and manufacturing process there are some problems, product quality has been unstable, especially in the microstructure, often appear C, D, E-type graphite, resulting in brittleness of the piston ring, plastic deformation, hardness Unqualified and a series of problems. Since the beginning of this year, in order to rapidly improve the quality of piston rings and solve the crux of the quality over the years, we have taken the form of a three-in-one organization to take the method of annihilating war and organizing the tackle in the double-leather movement centered on improving product quality. In order to thoroughly understand the situation and find out the reasons, we think it is necessary to find out the problems in practice and in practice so as to solve the problems. From the many pouring, we focus on strengthening the links between the various departments, especially the ingredients, melting and casting, etc.
