[0021] First, put the aluminum alloy into the high-frequency electric furnace 1, clamp it with the clamp 22, close the electric baffle 8, and use the high-frequency electric furnace 1 to heat it to 400-480℃. First, use the second electric push rod 23 to make the clamp 22 draw the aluminum alloy, and then anneal it. By accurately controlling the annealing temperature and time, as well as the drawing speed and strength, the production line achieves a perfect match of the aluminum alloy material in the annealing and drawing processes.
