7080 Aluminum Molten Metal Filtration is mainly used for continuous purification of aluminum water and has a good deep filtration effect.

The use of molten metal filtration technology is an effective means to improve the surface and internal quality of castings.

Filters have been widely used in industries such as auto parts, aerospace, machine tools, hydraulic components, pumps and valves, and wind power generation.

(Aluminum Oxide, Zirconium Oxide, Silicon Carbide, and Others) and Application (Metallurgical Industry Filter, Thermal & Sound Insulating Material, Automobile Exhaust Gas Purification, and Others) - Global Opportunity Analysis and Industry Forecast, 2021-2028."

The company produces various types of Ceramic foam Filter
products, which are sold domestically and exported to more than forty countries and regions.

Ceramic foam Filters
for Aluminum Instructions

1. Aperture selection

Continuous casting and rolling: 40~60ppi

Gravity casting: 10~30ppi

Semi-continuous casting: 30~70ppi

High-quality aluminum or plate: 40~90ppi

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 aluminum liquid from flowing by;

4. Evenly preheat the filter box and the filter plate to make it close to the temperature of the molten aluminum. Preheat to remove water and facilitate the initial instant filtration. The preheating can be implemented by electric or gas heating. Normally it takes about 15 %. ~30 minutes;

5. Pay attention to the change of the aluminum hydraulic head when pouring. The normal initial pressure head is 100~150mm. When the aluminum liquid starts to pass, the pressure head will drop below 75~100mm, and then the pressure head will gradually increase;

6. In the normal filtration process, avoid knocking and vibrating the filter plate, and at the same time make the launder full of aluminum water to avoid too much disturbance of the aluminum water;

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

How to use 5052 Aluminum Molten Metal Filtration

1. The position of the filter is as close as possible to the casting to achieve the best filtering effect. An open gating system is generally used.

2. Filtering area: The cross section of the flow channel where the filter is placed must be enlarged, the width of the filter support table is 5-12mm, and the gap between the filter and the filter seat is 0.5-1mm.

3. In order to prevent partial overload of the filter, it is recommended that the front and rear buffer height or the upper and lower buffer height of the filter be 1.5H~2.5H (H is the filter thickness).

Precautions for the use of ceramic foam filter


1. The Ceramic foam Filter
is made of ceramic, so you must be careful when handling it to avoid bumps.

2. The debris in the filter must be blown off first, and then put it into the filter holder.

3. After putting the filter into the filter holder, check that the top surface of the filter cannot be higher than the parting surface.

4. Store in a dry and ventilated place to avoid rain and excessive pressure.

5. Carry carefully to prevent collision and trampling during transportation.

6. If the shelf life exceeds 1 year, it is recommended to use it after drying.

Refractory Molten Aluminum ceramic foam filter Medium is an important part of aluminum casting. Ceramic foam filter plates have been widely used all over the world because of their convenient use, good filtering effect, and low price.

The ceramic foam filters can effectively remove the fineness of the aluminum water and reach the micron-level inclusions, so that the aluminum water enters a stable laminar flow, which is beneficial to the punching type.

It has a unique mullite corundum structure, good mechanical strength and chemical stability, and excellent aluminum washing properties.

The use of alumina Ceramic foam Filters to purify liquid aluminum plates, strip aluminum foils, and their products (such as tanker blanks, exquisite decoration materials, PS boards, etc.) have brought huge benefits. Manufacturers have the following obvious advantages for aluminum alloy profiles

1. Improve the extrusion survival rate: When the filter plate is used to purify 15% alloy extruded billets, we use specific die tracking and find that the extrusion speed has increased by 20% and the production efficiency has increased by nearly 6063.

2. The service life of the mold is prolonged and the number of mold repairs is reduced.

3. Reduce extrusion pressure: When the filter plate is used to purify molten aluminum, the pressure of 6063 is 3% higher than that of non-filtering.

The surface quality of aluminum profiles is significantly improved.

4. Ceramic foam Filter has the characteristics of large specific surface area, high mechanical strength, thermal shock resistance, etc.

5. Purification of metallic liquids, removal of non-metallic impurities and gases.

6. The filling of liquid metal is stable and the eddy current is reduced.

7. Simplify the pouring system and improve the process yield.

8.Refractory Molten Aluminum Filtering Medium can reduce the porosity of castings, optimize and refine the metal structure.

9. Improve the surface quality and mechanical properties of castings, and reduce the rejection rate of castings.

10. It can reduce the machining allowance, increase the service life of the tool, and reduce the casting cost.

Refractory Aluminium Alloys Filtration

Under normal circumstances, the following aspects should be paid attention to when installing and using alumina Ceramic foam Filter
plates

Choose the right filter plate

When selecting the size of the filter plate and the number of holes, factors such as the pouring flow range, the specific type of metal filtration, the maximum level, the total amount of filtration, and the cleanliness of the raw aluminum liquid should be considered.

The pretreatment of melt filtration cannot be ignored

Such as the normal deslagging, cleaning and refining of the furnace and holding furnace. Especially the online degassing device is still necessary, because it can not only reduce the hydrogen content in the melt, but also remove some non-metallic inclusions.

The filter should be matched with the square high temperature filter box

It is not only used for sealing, but also to prevent metal filtration from entering the box through the notch, to avoid too light foam filter plate, aluminum water failure.
