The substantial increase in the ceramic foam filter filtration cost of large castings is an important issue that the foundry must consider. The increase in……
The ceramic foam filter placement on the runner system is the ideal method to filter and purify the liquid metal. It is suitable for both……
Since argon is an inert gas and does not react with molten aluminum, it can replace the hydrogen in the aluminum melt, greatly reducing the……
Pinhole defects in aluminum alloy castings are the most prominent cause of casting scrap. The existence of pinholes not only reduces the effective working area……
The production of cold-rolled aluminum plates and strips all need to go through the production processes of cold rolling, finishing and heat treatment. The difference……
There are many types of insulating materials. According to the different working temperature, it can be divided into three categories: high temperature (above 1200℃) insulation……
Due to the high content of non-metallic inclusions, hydrogen, and sodium in the electrolytic aluminum liquid, the direct batching of 8079 aluminum alloy cast-rolled plates……
Nitrogen refining generally requires a lower temperature of the molten aluminum, although lowering the temperature reduces the diffusion rate of atomic hydrogen in the molten……
There are many purifying methods for molten aluminum in the furnace, including flux refining, and online degassing and filtration. Practice has proved that nitrogen refining……
It is more important to use suitable aluminum liquid purification methods, so as to eliminate pores and inclusions in aluminum castings. It is necessary to……
