Filter Box

The aluminum silicate filter box is scientifically composed of special ceramic fibers and inorganic ceramic materials. It is an essential accessory for forming a stable filter cavity when using a foam ceramic filter plate to filter aluminum and aluminum alloy melts. It has good thermal shock resistance, high strength, strong mechanical shock resistance and low thermal conductivity.

Applications

Suitable for casting applications with reticulated ceramic foam filtration.

product advantages:
1.It can be used directly at room temperature without worrying about thermal shock.
2.No thermal expansion and low thermal conductivity.
3.It can float in aluminum, reducing the possibility of refractory inclusions.

Operating Instructions

Clean the filter box.
Gently put the filter plate into the filter box, and press the sealing gasket around the filter plate by hand to prevent the flow of molten aluminum.
Preheat the filter box and filter plate evenly to make them close to the temperature of the molten aluminum. Preheat to remove moisture and facilitate initial instant filtration. Preheating can be carried out using electric or gas heating. Under normal circumstances, it takes about 15–30 minutes.
Pay attention to the change of the aluminum hydraulic head when casting. The normal initial pressure head is 100-150mm. When the molten aluminum begins to pass, the pressure head will drop below 75–100mm, and then the pressure head will gradually increase.
During the normal filtration process, avoid knocking and vibrating the filter plate. At the same time, the launder should be filled with aluminum water to avoid too much disturbance of the aluminum water.
After the filtration, take out the filter plate in time and clean the filter box.

Forming size standard, providing reliable support for effectively realizing the filtration efficiency of the foam ceramic filter plate. In addition to general specifications, it can be designed and manufactured according to customer needs.
