At the same time, due to the filtration process, the conventional and necessary measures taken to reduce the occurrence of inclusions in process operations such as smelting, furnace treatment, and casting cannot be ignored. It is also necessary to prevent re-contamination of the filtered clean aluminum liquid.<\/p>\nMolten Al Ceramic Filter Installation and Use<\/p>\n
1. Use the filter plate correctly:
\nThe size of the filter plate and the number of holes must be selected according to the flow range of the specific casting type, the maximum level of the metal during the filtration process, the total filtration volume, and the cleanliness of the original aluminum liquid.<\/p>\n
2. The pre-melting filtration treatment cannot be ignored:
\nSuch as ordinary slag from aluminum melting furnace and holding furnace, cleaning furnace; furnace refining. In particular, an online degassing device is still needed, because it not only reduces the hydrogen content of the melt, but also removes some non-metallic inclusions.<\/p>\n
3. The filter plate must be compatible with the square refractory block:
\nThe two are suitable for sealing to prevent the metal from flowing into the casting box from the gap without being filtered, and also avoid the foam filter plate from floating in the aluminum water due to the lightweight.<\/p>\n
4. Warm-up before use:<\/p>\n
Preheat to remove moisture and facilitate initial transient filtration. Electric heating or gas heating can be used for preheating. Normally, it takes about 15 minutes.<\/p>\n
5. In the normal filtering process, no slag is needed to avoid knocking and vibrating the filter plate. At the same time, the washing tank should be filled with molten aluminum, so as not to worry too much about molten aluminum.<\/p>\n
6. After casting, drain the metal in the flow cell and filter plate.<\/p>\n
7. Finally, clean the periphery and remove the filter plate after curing.<\/p>","protected":false},"excerpt":{"rendered":"
