摘要
采用Prefil-Footprinter铝渣检测仪、室温拉伸机、金相显微镜等多种检测分析手段,研究了精炼工艺对A356合金熔体渣含量及力学性能的影响。研究结果显示,加入精炼剂量为铝液总量的0.15%,以20 L/min流量通入高纯度氩气15 min,静置20 min后进行检测,此时A356合金熔体中渣含量最低,且力学性能最高。因此该精炼工艺将对现场A356铝合金锭熔炼和生产具有一定的指导意义。
This article used various detection and analysis methods such as PrefilFootprinter aluminum slag detector,room temperature stretching machine,metallographic microscope,etc.to study the effect of refining process on the slag content and mechanical properties of A356 alloy melt.The research results showed that adding a refining dose of 0.15% of the total amount of aluminum liquid,passing high-purity argon gas at a flow rate of 20 L/min for 15 minutes,and standing for 20 minutes for testing,the slag content in A356 alloy melt was the lowest,and the mechanical properties were the highest.Therefore,this refining process will have certain guiding significance for the on-site melting and production of the A356 aluminum alloy ingots.
