Aluminum Pipe chlorine gas purification. In the past, the active gas chlorine gas was used as a cleaning agent. During the process, the aluminum pipe produced many abnormally small AlCl3 when the chlorine gas was passed into the aluminum liquid. The bubbles were fully mixed in the aluminum liquid. The hydrogen dissolved in the aluminum liquid, the aluminum tube and some mechanical inclusions are adsorbed on the AlCl3 bubbles, and are discharged as the AlCl3 bubbles rise to the surface of the aluminum tube. Chlorine can also chlorinate certain elements that are more negative than aluminum. Aluminum tubes such as calcium, sodium, and magnesium all generate corresponding chlorides due to the introduction of chlorine, and the aluminum tubes can be separated. Therefore, the chlorination method is a very effective primary aluminum purification method.
Aluminum Pipe
Aluminum tube nitrogen purification method. This method uses an alumina tube as the filter medium, and N2 directly passes through the aluminum liquid. The aluminum tube liquid is continuously fed into the purification furnace, passes through the alumina ball filter layer, and is flushed with nitrogen, so non-metallic inclusions in the aluminum liquid And the dissolved hydrogen is removed, followed by continuous elimination, the aluminum tube so that the fine nitrogen bubbles are evenly distributed in the treated aluminum liquid to play a purification role.
There are many production methods for alloy pipes, and the scope of application is quite different. For example, seam pipes produced by split die can only be applied to civil pipes that do not require welds, and those that require welds need to bear A certain pressure is required, so seamless pipes produced by perforation and extrusion are required. For pipes with high dimensional accuracy, rails or stretching are required to meet the requirements of dimensional accuracy.
The above three are widely used in aluminum pipes produced by extrusion process, and cooperate with other cold processing methods. If you have any need, you can always contact the all-aluminum light alloy, which will bring you a high-quality product service experience. Among them, there are still many production methods, including hot extrusion method, hot extrusion-drawing method, Cold extrusion method, continuous extrusion method, etc.
If the surface of the aluminum tube is free from excessive oil stains, the aluminum tube may not be chemically cleaned before alkaline etching. It can be judged by the master of the parts by experience that the chemical cleaning work is not carried out, and the aluminum tube is directly subjected to alkaline etching, or the organic solvent is used to perform alkaline etching treatment directly.
