| Abstract: |
| Chemical composition and quality requirement of 7N01 aluminum alloy for high speed vehicle body profiles were introduced. Characteristics of 7N01 aluminum alloy and its difficulties to be melted & casted were analyzed. Addition technology of charges, smelting technology, furnace refining technology, and in-line treatment technology of Φ472 mm 7N01 aluminum alloy round ingot were investigated. Hot top casting process parameters of Φ472 mm 7N01 aluminum alloy round ingot were determined. Causes of casting defects in Φ472 mm 7N01 aluminum alloy round ingot were analyzed, and some corresponding measurements were determined and carried out. High quality Φ472 mm 7N01 aluminum alloy round ingot is produced to meet extrusion of high speed vehicle body profiles. |
