Product Description

High corrosion resistance zirconia ceramic foam filter

Description:
Zirconia ceramic filter is made of high-purity, high-quality zirconia, with a unique formula and advanced environmental protection technology. It has a foam-like porous structure of ceramic products, and has light weight, chemical stability, and porosity Large, corrosion resistance, high strength, good thermal shock resistance and other characteristics. Zirconia ceramic foam filter can be used to melt various types of steel, such as non-alloy, low-alloy, stainless steel and high-alloy, as well as nickel and cobalt-based super alloys. It can effectively filter small debris as small as micron impurities, slag, and refractory Materials and other non-metallic particles can effectively improve the microstructure of the casting; re-oxidation defects in the casting; improve the quality of the casting and reduce mold wear; simplify the casting system.
The filtering effect largely depends on the correct application of the filter. The filter is suitable for applications that have strict physical requirements and needs to be well supported, and metal will not bypass the structure. It is processed into strict dimensional tolerances during the production process. This combination of physical properties and precise tolerances makes it the first choice for molten steel, alloy steel and stainless steel.
In investment casting applications, it is very unusual for the filter to become clogged. When considering the size of the required filter, it is usually necessary to consider the filling speed of the mold. Generally speaking, a filter with a diameter of 50mm can meet the casting weight of 6kg, and a filter with a diameter of 70mm can meet the weight of 12kg.
The most common filter application technique is in the inverted cup. Ideally, an inverted cup specially designed and supplied for use with the filter will be used. This allows the "straight edge" filter to be placed in the proper position in the inverted cup.

Selection
1) Pore size is based on casting material and casting weight, regularly 10ppi and 20ppi for steel casting filtration.
2) Filter size is decided by the sculpt, fusion and the characteristic of ceramic foam filter.
Notice of Application
1. In order to reduce the impact of hot molten metal to filters, pouring bowl shall put down as low as possible from filters.
2. It is recommended to use compressed air to blow dust off from filter before usage.
3. Ceramic foam filters should be stored in dry place to avoid moisture.



How To Use
1.The closer the placement to casting cavity,the smaller the chance of secondary oxidation.
2.The design of the gating system should be simpler.It's not necessary to consider other slag blocking measures,which can improve the utilization rate of the sand type and the process yield.
3.The working area of the filter should be 4-6 times of the flow resistance section of the gating system to ensure that the pouring speed is not affected.
4.Selecting the appropriate filter according to the type of casting alloy and the pouring temperature,and it should not be overheated.
5.Selecting appropriate aperture to filter.
6.Filter can not be used to control pouring speed.
