Abstract

The invention discloses an aluminum alloy for producing a ladder stand pedal stick of a wind power tower. The aluminum alloy is prepared from the following raw materials: 0.37 to 0.39 percent of Si, 0.14 to 0.16 percent of Fe, 0.08 to 0.10 percent of Cu, 0.08 to 0.10 percent of Mn, 0.5 to 0.53 percent of Mg, 0.04 to 0.06 percent of Cr, 0.08 to 0.10 percent of Zn, 0.08 to 0.10 percent of Ti and the balance of Al and inevitable impurities. The invention further provides a preparation process of the aluminum alloy for producing the ladder stand pedal stick of the wind power tower. According to the aluminum alloy for producing the ladder stand pedal stick of the wind power tower, on the premise that all the performance of original aluminum alloy can be met, the cost is low, proportioning is convenient, the mechanical property and the use performance of a produced ladder stand guide rail profile can reach the standard, and the existing production requirements are met.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy preparation, in particular to an aluminum alloy used for producing wind power tower climbing ladder rungs. Background technique [0002] The inside of the wind power tower is connected with the vertical beam by ladder rungs, which are mainly used for maintenance personnel to climb and carry weight when climbing. The ladder rungs are generally produced by aluminum alloy ingots through extrusion, quenching, aging and other processes. Due to the special installation process of the rung profile, the rung profile is required to not allow cracking after swelling and riveting under the condition of meeting the mechanical properties, which puts higher requirements on the composition and production process of aluminum alloy. [0003] 6063 alloy belongs to Al-Mg-Si series medium strength and gold, because of its excellent extrudability and corrosion resistance, it is widely used in the production of...
