The main control points of aluminum rod extrusion production technology are three temperature, extrusion speed, tractor speed, extrusion rod speed, quenching and annealing. In order to improve the efficiency of aluminum extrusion production, good equipment is also the key, especially aluminum extrusion press, aluminum rod heating furnace, mold heating furnace these three big parts, the other most important is to have a good extrusion factory and extruder.

Outlet temperature of aluminum rod optimum extrusion temperature traction machine speed extrusion rod speed, mold filling cylinder temperature quenching temperature alloy form aging optimum metal physical properties, yield production efficiency thermal analysis Aluminum bar and aluminum bar before extrusion need to be pre-heated to reach the temperature close to fuse, so that the magnesium in the aluminum bar can be melted and flow evenly in the aluminum material. When the aluminum rod is put into the extruder, the temperature does not change much.

And when the extruder is started, the huge extrusion force of the extrusion rod will soften the aluminum material by the mold hole extrusion, produce a lot of friction, the friction force into temperature, so that the extrusion profile temperature exceeds the fuse temperature, at this time, and magnesium melting, to flow around, extremely unstable, the improvement of grace must not be higher than the solid solution phase line, otherwise aluminum will melt, and the profile can not be formed, Aluminum bar temperature should be maintained between 400-540℃, preferably 420-440℃, too high will cause tearing phenomenon, too low will reduce the extrusion speed, extrusion friction most will be converted into heat, resulting in temperature rise, temperature rise and extrusion speed and extrusion pressure is proportional to.

The above is a summary of the extrusion process of aluminum rod. Aluminum rod is widely used in industrial or manufacturing industry, and is widely used in various ways.
