Production method of conductor rail aluminum alloy profiles

The invention discloses a production method of conductor rail aluminum alloy profiles. The added internal control components comprise: 0.37 to 0.4 percent of Si, 0.55 to 0.59 percent of Mg, 0.035 to 0.004 percent of Mn, 0.005 to 0.01 percent of Ti, 0.0125 percent of V, 0.0006 percent of Cr, 0.003 percent of Cu, 0.03 percent of Zn, 0.1 percent of Fe, 0.0045 percent of Ni, 0.0006 percent of Zr, 0.002 percent of Bi, 0.001 percent of Sn and 0.0175 percent of Ga. The tensile strength of the produced conductor rail reaches 221 MPa, the yield strength of the produced conductor rail reaches 199 Mpa, the electric conductivity of the produced conductor rail reaches 57.06 percent to 57.4 percent IACS, the elongation percentage of the produced conductor rail reaches above 11 percent, and the technical parameters required by the conductor rail of rail traffic are met; when the profile and a steel plate are compounded, surface cracking on the deformed part is avoided, so normal operation is guaranteed after acceleration of
