We all know that temperature had a great influence on surface quality of the extruded section, so the temperature of every work are needed to control strictly, the 2024 aluminum rods at the time of production will be affected by aluminium rods in preheating temperature of the heating furnace, the temperature of ingot inside the cylinder and the mouth of the discharge temperature influence, the next 2024 aluminum rods manufacturer to introduce to you, 2024 aluminum rod temperature control method.

Preheating temperature in 2024 aluminum bar reheating furnace: The pre-heating of 2024 aluminum bar before extrusion shall ensure the uniform and thorough temperature of the 2024 aluminum bar before and after extrusion.When using gas heating furnace heating, do not put 2024 aluminum bar in 325℃-425℃ heating furnace for more than an hour, otherwise, affect the mechanical properties of 2024 aluminum bar, especially hardness.

Temperature of 2024 aluminum bar in ingot tube: 2024 aluminum bar is heated to the solid solution phase line temperature, so that silicon and magnesium flow evenly.If the temperature of the extruded profile exceeds the temperature of the solid solution phase line, then magnesium and silicon melt and flow around, extremely unstable.High temperature will cause tearing, and low temperature will reduce extrusion speed and production efficiency. Therefore, it is recommended to keep the temperature of 2024 aluminum bar between 420℃ and 440℃.

Outlet temperature of 2024 aluminum bar: In order to melt magnesium and silicon in the aluminum bar, the outlet temperature should not be higher than the solid solution phase line temperature. It should be kept between 520℃ and 550℃, otherwise it will lead to tearing and affect the surface quality of 2024 aluminum bar profile.

The above is about the temperature control method of 2024 aluminum bar. If you need to know the price of 2024 aluminum bar, please contact us.
