The squeezing temperature of industrial aluminum profile is an important process parameter in the process of squeezing production. In order to reduce the deformation resistance of the metal and reduce the pressure, it is necessary to improve the squeezing temperature of the industrial aluminum profile. However, when the extruded temperature is increased to a certain temperature, it is easy to appear hot and crispy, resulting in defects such as cracks. In order to avoid this phenomenon and to improve the speed of extrusion, it is necessary to reduce the squeezing temperature. These two conditions are contradictory. In order to reduce the deformation resistance and use a large extrusion speed at the same time, it is necessary to choose a good metal plastic temperature range.
However, in the production process of industrial aluminum profiles, metal and squeezing tube lining, mold, pad friction, and the deformation of the metal itself will increase the temperature of the metal and often break through the predetermined squeeze temperature range. The experimental results show that during the entire extrusion process, the squeezing temperature gradually increased, and the extrusion speed increased with the decrease in the metal content of the ingot. Therefore, due to the rise in the squeezing temperature and the acceleration of the extrusion speed, the end of the industrial aluminum profile products often cracks. The improvement of squeezing temperature during the squeezing process is related to the nature and squeezing conditions of industrial aluminum profiles. For industrial aluminum profiles, the temperature difference before and after the exit of the mold is between 10 C and 60 C.
In order to keep the squeezing temperature keep the metal's good plasticity range during the sequence of the metal in the industrial aluminum profile, it can be equal to the temperature squeeze. This is a new process explored by engineers and technicians over the years. In order to achieve equivalent temperature squeezing, automatic adjustment can be performed in all aspects of the squeezing process. For example, the temperature and the temperature of the squeeze tube can be heated, the mold can be cooled, the temperature can be adjusted, the extruded speed can be automatically changed, or it can be adopted to adopt it. Wait for speed squeeze. In addition, after replacing the mold, due to changes in the squeezing coefficient, the above conditions can also be adjusted accordingly. It can be seen that it is a very complicated process to realize the temperature of industrial aluminum profiles. At present, the steel ingot adopts gradient heating method to achieve approximation of temperature squeezing, which greatly improves the squeezing speed and product quality.
With the development of computer and digital programming technology in the industry, the modern extrusion machine has also been updated, equipped with FI control constant speed squeezing and TIPS control constant temperature extrusion. As long as the operator selects the button, according to the automatic programming technology of the device, you can get the required constant speed extrusion or constant temperature squeeze.
