在实际生产中发现,涂料喷涂对生产环境造成污染,并降低了生产效率;而真空系统的长期工作造成的巨大能耗制约了V法工艺的发展。采用V法工艺铸造铝合金铸件,并进行3个方面的探索:①提出无涂料V法工艺理论并在铝合金铸件条件下对EVA薄膜变化进行分析;②基于上述工艺理论基础,进行无涂料工艺试验,并分析该工艺适用于生产的条件;③为降低真空设备的持续工作能耗,尝试V法铸造与潮模砂铸造的复合工艺。
In actual production, it is found that paint spraying pollutes the production environment and reduces the production efficiency; and the huge energy consumption caused by the long-term work of the vacuum system restricts the development of the V process. V casting process using aluminum casting, and to explore three aspects: ① proposed V-coating process theory and in the aluminum alloy casting conditions EVA film changes; ② based on the theoretical basis of the process, the paint-free process Test, and analysis of the process for production conditions; ③ In order to reduce the continuous work of vacuum equipment energy consumption, try V-casting and sand molding sand composite process.
