Jeśli masz wyższe wymagania dotyczące wydłużenia i ciągliwości kół aluminiowych, powiedzmy, że aluminiowe tarcze typu temper O, Gorąco polecam producentów, którzy mogą bezpośrednio zastosować technikę wyżarzania do aluminiowych dysków, that is to say they will need to stamp the temper H18 aluminum coil to aluminum discs first and then anneal them to temper O. Only by resorting to such an annealing method, can they guarantee a better performance for aluminum sheet circles.
Here I would like to highlight that both the heating time and heat preserving time are of great importance. It often will take the furnace about 6 hours to be heated up to 200 degrees Celsius, and at the same time, the workshop needs to do oil-removing and fumes-discharging operations. Jednakże, they will continue to heat up the furnace to 380 degrees Celsius and are required to maintain them at this temperature for 20 hours, because this time duration hugely affects the elongation and ductility property of the aluminum sheet circles.
