Ceramic Filter Suppliers In India removes impurities in the aluminum melt and improves the purity of the metal melt to avoid bubbles and inclusions in the slab.

The filtration efficiency of the foam ceramic plate is closely related to its correct installation and use. At the same time, the conventional and necessary measures taken to reduce the occurrence of inclusions in smelting, furnace treatment, casting and other process operations cannot be ignored because of the use of filtration technology. It is also necessary to prevent the phenomenon of recontamination of clean aluminum liquid after Molten Metal Filtration.
Sometimes Ceramic Filter is also called Honeycomb Ceramic Filter, the name is different in different countries, but it has a short name of CFF.

Ceramic Filter Suppliers In India reminds Aluminium Foundry that its installation and use, in general, need to pay attention to the following aspects.

1. Correct selection of filter plate
The selection of the filter plate size and the number of holes must take into account factors such as the flow rate range of the specific casting type, the maximum metal level during filtration, the total filtration volume, and the cleanliness of the original aluminum liquid.

2. The pretreatment of the melt filtration can not be ignored
Such as normal slag slag removal and furnace cleaning of aluminum melting furnace and holding furnace; furnace refining, etc. In particular, the online degassing device is still necessary, because it can not only reduce the hydrogen content of the melt, but also remove some non-metallic inclusions.

3. The filter plate must be adapted to the square refractory brick
The adaptation of the two facilitates sealing, which not only prevents metal from flowing into the casting box from the gap without being filtered, but also prevents the foam filter plate from being too light and floating in aluminum water to fail.

4. Warm up before use
Pre-heating to remove water and facilitate initial initial filtration. Preheating can be implemented using electric or gas heating. Under normal circumstances, it takes about 15 minutes.

5. In the normal filtration process, there is no need to carry out slagging to avoid knocking and vibration of the filter plate. At the same time, the launder should be filled with aluminum water to avoid the worry of too much aluminum water.

6. After casting, put the metal in the launder and filter plate. There is a vibrator abroad, which is placed on the filter plate and vibrates for one minute. It can shake off about 75% of the remaining liquid metal from the filter plate.

7. Finally clean up for four weeks, and remove the filter plate after solidification.
