一、缝隙式浇注系统的特点缝隙式浇注系统是铝、镁合金铸造中常用的一种浇注系统。其结构形式。常用的铝合金和镁合金与氧的亲和力很强,易于氧化,而其氧化物比重和液体金属比重相差不大,生成的氧化物极难去除,所以要求液体金属平稳地充填型腔。一般情况下,对上注式浇注系统来说,液流在型腔内流动时,会引起冲击和喷溅;而对于下注式浇注系统,虽然液流进入型腔时流动平稳,但是液流在凝 First, the characteristics of slotted pouring system Slotted pouring system is aluminum, magnesium alloy casting a common casting system. Its structure. Commonly used aluminum alloy and magnesium alloy with strong affinity for oxygen, easy to oxidation, and the proportion of oxide and liquid metal, or less, the formation of oxides is extremely difficult to remove, so the liquid metal is required to fill the cavity smoothly. In general, for a pouring system, the flow of liquid will cause impact and splashing when flowing in the cavity. For a pouring system, although the flow is steady when it enters the cavity, In the condensate
