The correct choice of filter plate: in the selection of the size of the filter plate and the number of holes, to consider the specific type of metal filtration, large liquid level, the total amount of filtration and the cleanliness of the original aluminum liquid and other factors.

The pretreatment of melt before filtration should not be ignored, such as cleaning slag and cleaning furnace and holding furnace; Refinement, and so on. In particular, the on-line degassing device is necessary because it can not only reduce the hydrogen content in the melt, but also remove some non-metallic inclusions.

The filter plate should be matched with the square high temperature filter box: suitable for sealing, can prevent the metal from filtering into the box from the gap, also can avoid the foam filter plate is too light, aluminum water failure.

Preheating: preheating removes moisture and facilitates initial instant filtration. Preheating can be achieved by electric heating or gas heating. Normally, about 15 minutes.

Normal filtration process, no slag, avoid knocking and vibration filter plate. At the same time to use enough water, avoid aluminum and aluminum water movement too much.

After casting, drain clean and ceramic filter plate metal. As a vibrator, installed on the filter plate, vibration for one minute, 75% of the filter plate can get rid of the retention of molten metal.

Remove ceramic filter plate by condensation after cleaning the surrounding area.
