Abstract:
This paper studied the dross composition and dross Mechanism of nozze cavity on Hazelett continu-ous casted and rolled AA5052 aluminum alloy by seanning electron mieroseopy (SEM ),energy dispersive a.nalysis ( EDS ) ,X-ray diffraetion ( XRD), ete. Using The Gibbs free energy thermodynamie funetion ealeulat.ed driving forees of forming dross compound of nozzle cavity and analyzed formation on reaclion of dross compound of nozzle cavity. The results showed that dross eompound of nozzle eavity consisted of spinel, forsteriteFlorisil,ete. The Si0, or Al,0, in nozzle cavity reacted with Al, Mg and Mg0 in AA5052 aluminum alloy melto MgAl204,Mg2SiO4 , MgSiO3, which were mainly spinel composition during casting process, eventually lead.ing to drss of nozzle cavity.
