How to control the extrusion temperature of aluminum profiles?

Update time : 2022-10-13 19:34:42

In order to reduce the deformation resistance of the metal and reduce the extrusion force, it is necessary to increase the extrusion temperature of industrial aluminum profiles.

When the extrusion temperature is increased to a certain temperature, hot brittleness is prone to occur, and defects such as cracks are generated. Therefore, in order to avoid this phenomenon, in order to increase the extrusion speed, it is necessary to reduce the extrusion temperature. These two conditions are contradictory to each other. In order to reduce the deformation resistance and adopt a larger extrusion speed, it is necessary to select a temperature range with good metal plasticity.

1. Heat-resistant aluminum alloys that can be used at higher temperatures without softening. The main ways to improve the thermal strength of aluminum alloys are solid solution strengthening, excess phase strengthening and grain boundary strengthening. It can also be divided into heat-resistant deformation aluminum alloys (including heat-resistant forged aluminum alloys, heat-resistant hard aluminum alloys) and heat-resistant cast aluminum alloys according to different processing techniques. Mainly used for parts that work at 150-300℃, such as turbine compressor vanes, welded containers, pistons, etc.

2. Instrument introduction details. Temperature detection is divided into two categories: contact type and non-contact type.

In the extrusion production of aluminum profiles, the usual practice is to use a fast thermocouple contact method to detect the temperature of the aluminum material. During the extrusion process, the profile keeps moving, and the detection element must move with the profile, which cannot maintain online monitoring. Different methods, the profiles are cooled immediately after being ejected from the mold, resulting in a large deviation in the detection temperature, so it is difficult to obtain the correct temperature and speed matching.
