Generally, the soaking bar of 6000 series alloy should be controlled at about 450-500, and the height of non-soaking bar is generally 10-20 degrees. The core of extrusion temperature control is the outlet temperature, which is generally between 540 and 580. Low strength is not enough, high strength is easy to burn. For example, the temperature of the front casting rod should also be adapted to the temperature of the rear outlet. ...
