精炼工艺对A356铝合金熔体渣含量及性能的影响OACSTPCD

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.
