Manufacturing method of 7-series aluminum alloy transmission tower sectional material
The invention discloses a manufacturing method of a 7-series aluminum alloy transmission tower sectional material. The 7-series aluminum alloy transmission tower sectional material is of an abnormally-shaped right-angle structure. The abnormally-shaped right-angle structure is characterized in that an extension section 3 is connected to the angular bisector of a right-angle side 1 and a right-angle side 2, and a stop block 4 is arranged at the tail end of the extension section 3. Aluminum alloy components used by the 7-series aluminum alloy power transmission tower sectional material include 0.3%-0.6% of Mn, 1.5%-2.2% of Mg, 6.7%-7.2% of Zn, 0.07%-0.08% of B, smaller than or equal to 0.1% of Si, smaller than or equal to 0.5% of Fe, 0.2%-0.5% of Cu, smaller than or equal to 0.3% of Cr, smaller than or equal to 0.2% of Zr, smaller than or equal to 0.1% of Ti, smaller than or equal to 0.05% of other single impurity element, smaller than or equal to 0.15% of total impurity content and thebalance Al. The manufacturing method of the 7-series aluminum alloy transmission tower sectional material comprises the steps of cast ingot preparation, cast ingot extrusion, on-line quenching and theheat treatment technology.
