Product Detail


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, the temperature of the aluminum coil is too low and the extrusion speed is too slow. The exit temperature of the aluminum profile can not reach the solid solution temperature, and it can not get the solid solution strengthening effect. The extrusion temperature and the extrusion speed of the aluminum coil are controlled reasonably, so the extrusion temperature of the extruding machine is kept at the lowest solution temperature.
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 6061 aluminum coil 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.
