      1, the inhomogenization treatment of ingot can make the Mg2Si phase separated from ingot arrangement unable to re solve in a relatively short time during kneading, resulting in inadequate solid solution and influence on commodity function, and strong demand for homogenization of aluminum coil ingot.
      2, when the low temperature aluminum roll kneading, kneading speed is too slow, not to roll aluminum profiles of solid solution temperature at the outlet temperature of kneading machine, not to the solid solution strengthening effect; the reasonable demand for aluminum roll kneading manipulation temperature and kneading speed, the profiles in the kneading machine outlet temperature maintained at a minimum solution temperature above.

      3. The ingot components are not qualified, the content of Mg and Si in ingot can not reach the standard request, and the quality management of ingot is strengthened.
      4, aluminum coil outlet fan, air guide is not enough, aluminum volume caused by cooling speed is slow, cannot make the profile in the shortest time is reduced to 200 DEG C, the coarse Mg2Si premature separation, so that the solid solution phase reduction, affecting the mechanical function profile after heat treatment; strengthening cooling conditions demand conditions of the factory equipment, atomization cooling equipment, in order to reach the lowest request of 6063 alloy gradient cooling.
      5, with aging technology and hot air circulation is not smooth or thermocouple device position is not accurate, resulting in inadequate or aging aging; reasonable that aging technology demand is strong, the aluminum coil accurate equipment to ensure accurate placement of thermocouple, hot air circulation and profile.
