Aluminum coils have won the favor of a large number of users with their unique characteristics. We also know a lot, but the problem of processing aluminum coils is not very clear yet. Today we analyze the problem of aluminum coil processing.
1. The uneven treatment of the ingot makes the Mg2Si phase separated from the ingot arrangement unable to be redissolved in a short period of time, resulting in insufficient solid solution, which has a greater impact on the function of the product and the uniformity of the aluminum coil ingot. demand is strong.
2. When kneading low-temperature aluminum rollers, the kneading speed is too slow, which cannot make the solid solution temperature of the aluminum alloy profile at the outlet temperature of the kneader and cannot achieve the effect of solid solution strengthening; the operating temperature and kneading speed of the aluminum roller kneading It is a reasonable requirement that the temperature profile at the kneader outlet be maintained above the minimum solution temperature.
3. The composition of the ingots is unqualified. The magnesium and silicon content in the ingots do not meet the standard requirements. The quality management of the ingots must be strengthened.
4. The air outlet of the aluminum coil has insufficient air guide, resulting in a slow cooling rate of the aluminum coil, which cannot reduce the profile to 200°C in the shortest time, causing premature separation of crude Mg2Si, causing solid solution phase reduction and affecting the mechanical properties after heat treatment; strengthening the factory Equipment, the cooling conditions of atomization cooling equipment require conditions to meet the minimum requirements for gradient cooling of 6063 alloy.
5. As the aging technology and hot air circulation are not smooth or the position of the thermocouple device is inaccurate, resulting in insufficient aging or aging; reasonably, the aging technology requires strong and accurate equipment for aluminum coils to ensure accurate placement of thermocouples and heat. Air circulation and contours.
