摘要
采用自行设计的单体活塞环覆膜砂砂型在实际生产条件下生产了240活塞环,并与湿型砂生产的活塞环进行了组织与性能的对比研究。结果表明,采用所设计的覆膜砂砂型生产的活塞环完全符合各项技术指标要求,在硬度方面,两种方法生产的活塞环相当,而在金相组织、抗弯强度和耐磨性等方面,覆膜砂生产的活塞环表现出了比湿型砂生产的活塞环更佳的综合性能。
The 240 en-b!0ck piston rings were produced by self-designed shell core in practical plant conditions, and the microstructure and properties of the piston rings were compare with that produced by green-sand. The results show that the technical parameters of the piston rings produced by shell core process can meet the technical criterion of the piston ring completely. The hardness of the piston rings produced by the two processes is almost equivalent, while the complex properties of the piston rings produced by shell core process are better in metallurgical microstructure, bending strength and abrasion resistance etc.
