本文以铁路车辆轴瓦为例,从生产实际出发,探讨了铅基轴承合金(球铁瓦体浇挂白合金)的浇挂质量。文中抓住抛光、预热、配料、熔炼、浇挂、检验……等主要工序,较系统地介绍了这种轴承合金的生产工艺,强调了在技术管理和质量管理等方面应重视的各个细小环节,并就铅基轴承合金浇挂质量提出一些改进性的商榷意见,对生产实践及理论探讨具有一定参考价值。
In this paper, taking the railway vehicle bearing as an example, starting from the actual production, discussed the quality of the lead-based bearing alloy (ductile iron tile body pouring white alloy) casting. The article seizes the main processes such as polishing, preheating, ingredients, smelting, pouring, testing ...... and so on, systematically introduces the production process of this bearing alloy, emphasizing the importance of technology in the management and quality management of all small Link, and put forward some improvement suggestions on improving the quality of the lead-based bearing alloy casting, which has some reference value to the production practice and theory discussion.
