金属型铸造铝铸件常见缺陷是二次氧化夹渣和气孔。经过较长时间的生产实践和观察,笔者认为这二种缺陷与浇注系统密切相关。本文就浇注系统形状及金属液导入方式对铝铸件质量的影响进行分析。 一、常用的浇注系统形状 金属型分型方式大致有三种:水平分型、垂直分型和综合分型。由于金属型铸造先开型后取件的特点,为使金属型结构简化和铸件取出方便,其浇注系统大多设在分型面上。常用形式有上注、底注和侧注三种。
Metal casting aluminum castings common defects are secondary oxidation slag and pores. After a long period of production practice and observation, I believe that these two defects and pouring system is closely related. In this paper, the pouring system shape and liquid metal into the way of aluminum casting quality analysis. First, the commonly used pouring system shape Metal type classification generally has three kinds: horizontal type, vertical type and comprehensive type. Due to the characteristics of metal casting after the first open-pick, in order to simplify the metal structure and easy to remove the casting, the casting system is mostly located on the parting surface. Common forms of betting, betting and side note three.
