Product Description

The structure of an extruded ingot

The structure of the extruded ingot is also a key to ensure the brightness of the polished aluminum surface.

The structure of the extruded ingot is guaranteed by casting and homogenizing. First of all, due to the low content of Fe alloy, the microstructure of the 6463 alloy is more likely to appear coarse grain. At the same time, because TiB2 can reduce the brightness of chemical polishing, the refinement of the 6463 microstructure must be very careful. We consider using Al-Ti-C refinement to solve the thinning problem and avoid the influence of TiB2.

On the other hand, bulky particles in the casting increase the dent defects in the extruded aluminum material and cause tearing. The reason is tearing or metallographic formed by the reaction of eutectic phase with low melting point, which leads to the decrease of the temperature of the liquid phase, so must be eliminated by accelerating the cooling speed and reduce the casting mold liquid hole concentration; at the same time as the organization is more uniform, must carry on the homogenization treatment, the Fe phase transition, with equiaxed particles distribution and main dimensions of not more than 3~4m, Mg2Si precipitates in all phase and uniform distribution in 'grains, mainly the particle size is less than 05m.

The effect of homogenizing treatment on aluminum rods is to reduce the internal stress and to reduce the friction force of the products during extrusion and obtain a good surface. In addition, the casting temperature of the molten aluminum and the temperature of the cooling water are obviously improved on the extrusion surface.

Extrusion die and extrusion process

Impact on the quality of polished aluminum extrusion mold in two aspects: on the one hand, because of the mould work or aluminum surface defects caused by the air knife with which might affect the subsequent polishing quality. On the other hand, due to the surface defect due to the flow cavity, the shunt cavity, the bridge and the welded chamber, some of the defects can only occur after polishing or oxidation. Therefore, the quality of the mould is very important to the surface quality of the polishing material, and the working band is not good and the die life is very short.

Secondly, the flow of the mould, the shunt, the mould bridge and the welding position must be considered according to the thickness of the aluminum, the ratio of the extrusion, the shape and the polishing surface. Make sure the following requirements: sufficient deformation processing quantity, especially the thickness and small extrusions are more important than aluminum, ensure the organization structure is consistent. Sufficient welding; Move the metal flow even before entering the work zone, minimize the dead zone and reduce the impact of metal on the work zone.

In addition to the excellent castings and molds, there are several important points to be made in the extrusion process:

First, you need to have the right squeeze ratio, usually = 25 ~ 50, too big or too small will affect the quality of the polished material.

Second, extrusion temperature (extrusion outlet temperature) in the guarantee of 6463 alloy Mg2Si phase full solid solution on the premise of try to control the low temperature (about 500!), and combined with large air cooling. For different types and extruded aluminum, how to adjust three temperature and squeeze speed, to achieve the control of aluminum outlet temperature is the key to guarantee the quality of polishing.

In addition, the protection of the surface of the extruded billet is also an important part of the polishing quality.
