The 6061 aluminum bar is obtained through extrusion, so it is necessary to control the temperature of all aspects during extrusion production. Then the 6061 aluminum bar manufacturer will introduce the temperature of 6061 aluminum bar.

1. The preheating temperature in the aluminum bar heating furnace

The pre-heating of the 6061 aluminum bar before extrusion is carried out in the aluminum bar heating furnace. The uniform and thorough temperature of the 6061 aluminum bar before and after extrusion is to be ensured.In the use of gas furnace need to pay attention to the temperature and time, 6061 aluminum bar in 325℃-425℃ heating furnace not more than an hour, otherwise, affect the mechanical properties, especially hardness.

2. The temperature of the aluminum bar in the spindle barrel

The appropriate temperature is related to the tonnage of the extrusion type, the type and shape of the extrusion material, the temperature of the die and the extrusion speed.

By heating the 6061 aluminum bar to reach the temperature of the solid solution phase line, the magnesium solution will be made. Due to the friction between the aluminum material and the wall of the ingot cylinder during extrusion, the temperature will rise by about 38℃, making the temperature of the extricated 6061 aluminum bar exceed the temperature of the solid solution phase line. At this time, the magnesium and silicon melt and flow around, which is extremely unstable.It is recommended that the temperature of 6061 aluminum bars be maintained between 420℃ and 440℃.

3. Outlet temperature

To achieve solid solution of magnesium and silicon, the outlet temperature should be maintained between 520℃ and 550℃.It cannot be higher than the temperature of solid solution phase line, otherwise it will affect the surface quality.
