The slag mixed into the ingot or other non-metallic impurities in the ingot are called non-metallic inclusions, commonly known as slag inclusions. Its fracture features are striped or flake-shaped, and the microstructure features are mostly black linear, massive, and flocculent disordered tissues, with obvious color difference from the matrix. So slag removal is important for high-quality ingot.<\/p>\n

Non-metallic inclusions (slag inclusions) can usually be found when inspecting the transverse low-magnification test piece and fracture of the ingot. For the ingots used for extrusion of these two alloys, there should be no more than two slag inclusions on the ingot test piece, and the single area is less than 0.5mm^2, otherwise it will be rejected. Non-metallic inclusions (slag inclusions) are the most frequently occurring waste products in aluminum alloy ingots. According to statistics, by weight, ingots scrapped due to slag inclusion account for about 10% to 25% of the total waste.<\/p>\n

Slag inclusions are usually caused by slag, lining fragments and larger oxides that fall into the ingot along with the liquid metal during the casting process.<\/p>\n
