摘要

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。

Abstract

Some problems in effects of coatings spraying on environment and efficiency as well as long-term operation of vacuum system in practical production restricted the development of V-EPC technology.V-EPC casting aluminum alloy castings were conducted.The principle of V-EPC with coating-free was presented

and EVA film change for aluminum alloy was analyzed.Based on the analysis of principle

V-EPC with coating-free was conducted

and the proper parameters were investigated.In addition

to decrease the energy consumption of vacuum equipment

compound casting of V-EPC with green sand was presented.
