ã€China Aluminum Industry Network】 (1) Casting rod heating method Casting rod heating adopts industrial frequency induction heating. The characteristics of this heating method are:
a. The heating time is short, and it can reach about 500°C within 3 minutes;
b, temperature control accuracy, error does not exceed ± 3 °C.
If the furnace is heated slowly, it will cause precipitation of Mg2Si phase, affecting the strengthening effect.
(2) Extrusion changes the following factors and reasonably formulates the 6082 alloy aluminum extrusion process.
1,6082 alloy deformation resistance, so cast rod temperature should be biased upper limit (480-500 °C);
2, the mold temperature should also be high;
3, in order to prevent shrinking or bubble, oxide scale, impurities involved, pressure should be left longer;
4, to make the main strengthening phase of the alloy Mg2Si completely solid solution, it must be ensured that the quenching temperature above 500 °C, solid extruded extrusion outlet temperature should be controlled at 500-530 °C;
5,6082 alloy quenching high sensitivity. The alloy contains Mn, which promotes the formation of intragranular intermetallic compounds and has an adverse effect on the quenching performance. Quenching requires high cooling intensity and fast cooling rate. It must be quenched by water to rapidly reduce the temperature to less than 50°C.
After 6ã€6082 alloy aluminum profile sawing, the frame shall be protected at a certain interval, and it shall not be discharged too densely.
