The Temperature Control of the Industrial Aluminum Profile During the Squeezing Process

The squeezing temperature of industrial aluminum profile is an important process parameter in the production process. In order to reduce the deformation resistance of the metal and reduce the squeezing pressure, the squeezing temperature of the industrial aluminum profile needs to be improved. However, when the squeezing temperature is increased to a certain temperature, it is prone to hot crispy phenomenon and cracks. To avoid this phenomenon to increase the squeezing speed, the squeezing temperature must be reduced. These two conditions are contradictory, so in order to reduce the deformation resistance and have a large squeeze speed, the squeezing temperature range must be controlled. However, in the squeezing production process of industrial aluminum profiles, the friction between the metal and the squeezing cylinder, mold, and pads, and the deformation of the metal itself will increase the temperature of the metal, and often exceed the pre -selected squeeze temperature range. Experiments have shown that during the entire squeezing process, the squeezing temperature gradually increased, and the squeezing speed gradually increased as the metal of ingot casting metal decreased.

Therefore, the end of the industry aluminum profile products is often cracking due to the elevation of the squeezing temperature and the acceleration of the extrusion speed. The elevation of the squeezing temperature during the squeezing process is related to the nature and squeezing conditions of the industrial aluminum profile. For industrial aluminum profiles, the temperature difference between the front of the metal at the outlet and the back of the mold exit is between 10-60 C. In order to keep the squeezing temperature within the process of the production of industrial aluminum profiles in a better metal plastic temperature range, it is best to use equivalent squeezing. In order to achieve equivalent squeezing, there are many conditions, so that all links in the squeezing process can be automatically adjusted.

For example, the temperature of the gradient heating ingot and the temperature of the extrusion cylinder can cool the mold and adjust the temperature, and can automatically change the squeezing speed or use speed.

In addition, after changing the mold, due to changes in the squeezing coefficient, the above conditions can also be adjusted accordingly.

It can be seen through an article that the temperature squeezing of industrial aluminum profiles is a very complicated process. At present, the gradient heating method is mainly used to achieve approximation of temperature squeeze, which can also greatly improve the squeezing speed of industrial aluminum profiles and improve their product quality.
