【 Building materials network 】Processing Aluminum profile When housing, the ambient temperature will affect the aluminum profile housing. With the change of extrusion conditions, the extrusion temperature and speed are also changing. When extruding the aluminum profile shell, the extrusion temperature is low, the extrusion speed is slow, and the heat conduction of the aluminum shell is high. What harm does low temperature do to aluminum shell? What are the specific aspects?

1、 Structural changes

Generally speaking, when the aluminum profile shell is cooled, the material structure changes, which makes the material qualitative and anisotropic. It may lose its original characteristics or changes. At this time, it can only reduce the probability of variation and guide it to develop in a favorable direction.

2、 Cause processing embrittlement

The change of aluminum profile shell will lead to crystal damage, lattice change, and a sharp drop in its own plasticity index, and the aluminum profile shell will become brittle, brittle in use, and easy to deform.

3、 Influence physical and chemical properties

1. Low temperature will destroy the chemical structure of aluminum profile shell, leading to chemical reaction and destroying the original covalence key Corrosion of aluminum shell.

2. The destruction of intergranular material leads to the disorder of grain order.

3. Destroy the physical structure of the aluminum housing. When they are processed at low temperature for a long time, the density will change and small damage will occur.

Temperature has a great influence on the surface quality of extruded profiles, so the temperature of each process should be strictly controlled. The places to be controlled include temperature during extrusion, temperature rise caused by friction during extrusion, ingot container Temperature, mold temperature, aluminum bar temperature and heat treatment The temperature of. Hongfa Shunda shell manufacturer has found a more suitable production process based on years of production experience to ensure that the product quality is better guaranteed.
