Background

At present, the production of domestic aluminum profiles is gradually shifted from the production of small-sized products to the production of industrial materials, particularly the profiles for transportation, and correspondingly, factories which specially extrude train, subway, vehicle and automobile profiles or mainly produce the profiles are built.

When the heating temperature is higher than the melting point of the eutectic with low melting point, the phenomenon of remelting the eutectic with low melting point and the grain boundary is called overburning. When an aluminum alloy raw material enters an ingot furnace for heating, due to the self limitation of a heating induction system of an electromagnetic induction heating furnace, a part of aluminum alloy ingots heated by the heating furnace has an overburning phenomenon, and whether the overburning of the aluminum alloy ingots can pass through macroscopic texture characteristics is judged, namely, when the overburning is serious, the color and luster of the surfaces of the ingots and processed products become dark and black, and sometimes surface blistering is generated; alternatively, the microstructure is typically characterized by the presence of terrace patterns in the matrix in contact with the remelted product as a result of electron microscopy studies of the microstructure in the vicinity of the remelted triangles. The terrace pattern is a crystallization step with dendritic crystal outcrop, and is the same as the dendritic crystal outcrop on the surface of the loose inner wall, which indicates that the tissue at the position is subjected to remelting;

after the alloy is over-sintered, the eutectic with low melting point is remelted and solidified in the crystal boundary and the matrix, so that the state that the tissues at the position are closely connected before the over-sintering is changed, the continuity of the alloy is generally damaged, and the mechanical property, the fatigue, the corrosion performance and the like of the alloy are seriously influenced. Since the alloy overburning cannot be eliminated by heat treatment or working distortion, any ingot or article overburning is an absolute waste product. Especially, alloys used in the aerospace industry cannot be allowed, but the existing aluminum alloy ingot production line has no special device for manually screening over-burnt aluminum alloys, so that the over-burnt aluminum alloy ingots cannot be removed from products, and the products flow into the market, and have certain potential safety hazards.
