Study on Manufacturing Process and Applying of Galvalume

Abstract:

Annealing and dip galvanizing treatments of Galvalume were studied by using methods of Gleeble thermal simulation experiment and optical microscopy (OM), scanning electronic microscopy (SEM), X-ray energy dispersive analysis (EDAX), X-ray diffraction (XRD) and so on. Meanwhile, surface morphology, microstructure, phases and the respective compositions of Al-Zn alloy coating plate were analyzed. The results show that decreased rate and prolonged time of annealing treatment cause less effect on process ability of product, which all because of the short time of annealing process in continuous aluminum-zinc treatment. However, coarse grain which causes low strength, high elongation and r value occurs when rising annealing temperature. To get better coated surface, in-zinc pot temperature should be controlled in the range of 590~610°C, and height of air-knife nozzle should be kept in the range of 150~200mm. Surface layer of 55％Al-Zn alloy coating is covered by Al-Zn alloy, the intermediate alloy layer is consisted of binary and ternary compounds, such as θ phase (FeAl₃), Al_0.3Fe₃Si_0.7 and Al_3.21Si_0.47.
