Metal liquid filtration technology is an effective means to improve the surface and internal quality of castings. Filters have been widely used in automotive parts, aerospace, machine tools, hydraulic parts, pump valves, wind power and other industries. EUREKA's filter products, selling well in China and exporting to more than 40 countries and regions.

Product features:

◎ F-4 type foam ceramic filter plate is mainly used for continuous purification of aluminum water with good deep filtration effect.

Usage:

1. Aperture selection

Continuous casting and rolling: 40~ 60PPI

Gravity casting: 10~ 30PPI

Semi-continuous casting: 30~ 70PPI

High quality aluminum or sheet: 40~90 PPI

2. Clean the filter box;

3. Gently put the filter plate into the filter box, and press the sealing gasket around the filter plate by hand to prevent the liquid aluminum from side flow;

4. Preheat the filter box and filter plate evenly, make it close to the temperature of liquid aluminum, preheat to remove moisture, and is conducive to the initial instantaneous filtration, preheat can be carried out by electric or gas heating, it takes about 15~30 minutes under normal circumstances;

5. When pouring, pay attention to the change of the aluminum hydraulic head. The normal starting pressure head is 100~150mm.

6. In the normal filtration process, avoid knocking and vibrating the filter plate, and at the same time, the flow tank should be filled with aluminum water to avoid too much disturbance of aluminum water;

7. After filtering, remove the filter plate and clean the filter box in time.

Foam ceramic/straight hole filter method of use

◎ The filter position is as close to the casting as possible to achieve the best filtering effect. Generally, open gating system is adopted.

◎ Filtration area: the cross section of the sprue where the filter is placed must be expanded, generally 2~4 times the normal cross section of the sprue, the width of the filter support platform is 5~12mm, and the gap between the filter and the filter seat is 0.5~1mm;

◎ When multi-plate filter is used for large castings, the water flow through each filter must be balanced;

◎ The height of the buffer before and after the filter or the upper and lower buffers is recommended to be 1.5H~2.5H (H is the thickness of the filter) to prevent local overload of the filter;

◎ The casting height should not exceed 300mm when the filter is directly impacted. The filter should be properly thickened when the filter is directly impacted.

◎ The new product design filter can be put into mass production only after initial test and small batch verification that there is no abnormality.

Precautions for the use of foam ceramic/straight hole filters

◎ The filter is ceramic, it must be handled with care to prevent bumping;

◎ Before putting the filter seat in the filter must blow the filter internal debris;

◎ After putting in the filter seat, check that the top of the filter can not be higher than the parting surface;

◎ When the casting temperature is low, the zirconium filter needs preheating.

Storage and shelf life of foam ceramic/straight-hole filter

◎ Storage in dry and ventilated place, no rain and heavy pressure;

◎ The handling process should be handled with care to prevent bumping and trampling;

◎ The shelf life is three years, if the storage period is more than one year, it is recommended to use after drying.
