Wrought aluminum and aluminum alloy ingot casting and machining product defects Part 2. strip casting defects1 ScopeThis section provides the twin-roll continuous casting aluminum products in the definition of common defects, features, and analyzes the main causes. This section applies to the analysis twin roll casting machine production of aluminum and aluminum alloy casting with deformation defects and determination. 2 Definition of Defects, features and main causes 2.1 Delamination crack laminationcrack Casting phase with a low melting point and by the emergence of subsurface Fe, Si and other impurities are separated layered. Sometimes stratification extends to the surface, forming a cleft horseshoe Mouth [in Figure 1a)]. Extend or extends to such surface defects called delamination crack. Delamination crack is generally separated and each of the groups Now [as shown in Figure 1b)]. Crack organizations on both sides are quite different, the surface of the low-melting phase and less impurity phase, coarse grains, the internal low-melting phase and miscellaneous Quality with more fine grain size. Main causes. delamination crack is due to the casting tape during solidification, solidifying shell is less than the shear strength of the adhesive surface area and the central deformation zone Gache attached between stress due. a) surface b) lateral sectional Figure 1 delamination crack 2.2 Article crack through run-throughcrack Roll with the surface of the curved, V-shaped or no fixed transverse crack or split, crack formation or band arranged along the rolling direction. It to To the same airway, surface segregation, and other defects associated with coarse-grained. The main causes. a) feeding nozzle partial blockage; b) local damage lips or slagging. 2.3 Tropical hotstrip Roll with local unaffected rolling deformation, crystalline surface having a free area (Figure 2). Serious defects will penetrate the thickness, forming a hole Hole; tropical irregular shape, with varying degrees of depression. Recessed surface irregularities, often accompanied by cracks, sometimes floating segregation Effluent. The main causes. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 26492.2-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 26492.2-2011_English as soon as possible, and keep you informed of the progress.
