Hot rolled aluminum sheet factory can manufacturing high quality hot rolling aluminum sheet plate product with fast speed. The heated aluminum ingot is rolled on the roller table through multiple passes of reversible rolling to a thickness of 18~25mm, and then double-coiled reversible type finishing rolling, after 3 to 5 passes, the thickness of aluminum sheet can reach 2.5 mm. The production capacity can reach 150kta. This configuration is the best configuration for hot rolling mills. In addition to the immature production technology of cans, it can produce various aluminum sheet plates and strips.
When the hot rolled aluminum sheet factory is heaten the aluminum plate processed, the coarse dendrites and various inclusions in the as-cast metal billet are elongated along the deformation direction, so that the dense inclusions between the as-cast metal dendrites are gradually arranged in a fibrous shape along the deformation direction. Heat treatment cannot eliminate or change the streamline distribution in the workpiece. The advantages of hot rolled aluminum sheet are:
1, Hot rolling can transform the as-cast structure with lower plasticity to the deformed structure (processing structure) with higher plasticity, which can significantly improve the processing performance of the aluminum sheet metal.
2, Generally, the deformation resistance of the metal decreases with the increase of temperature, so the deformation resistance of the metal during hot rolling is lower than that during cold rolling, which can significantly reduce the energy consumption during rolling.
3, As the temperature rises, the plasticity of the aluminum sheet increases, so the plasticity of the metal during hot rolling is better, that is to say, the processing performance of the aluminum metal is better, so that a larger amount of deformation can be used for rolling, and the aluminum can also be reduced. The edge cracking and fracture loss of the aluminum sheet metal can improve the yield rate of the metal.
4, Because the metal has higher plasticity and smaller deformation resistance during hot rolling, hot rolled aluminum sheet factory can use large ingots, which can not only increase productivity and yield, increase rolling speed, but also create a continuity and automation of the rolling process condition.
