About This Item

Instructions:
Check and clean the debris on the surface of the filter box to keep the filter box clean and free of damage, check the safety of every piece of equipment on the production line, including furnaces, launders, filter boxes and hot top casting machines.

Gently put the filter plate into the filter box, and press the sealing gasket around the filter plate by hand to prevent the aluminum liquid from bypassing or floating.

Preheat the filter box and filter plate evenly to make them close to the temperature of molten aluminum, and the preheating temperature of the filter plate is not lower than 260℃. Preheating to remove adsorbed water helps to open the initial filter pore size in an instant, preventing partial pore blockage of the filter plate due to thermal expansion and contraction. Electric or gas heating can be used for preheating, and normal heating takes 15-30 minutes.

After the molten aluminum comes out of the filter box, it passes through the launder to the next casting platform. At this time, pay attention to the changes in the aluminum draulic head, and maintain the normal demand for the flow of aluminum liquid. 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 liquid.
After filtration, take out the filter plate in time and clean the filter box.
