Specification of High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plate

This Heat Porous Alumina Al2O3 Porcelain Foam Filter Plate gets rid of pollutants from liquified metals. It is made from pure aluminum oxide. This product deals with extreme warmth very well. The filter framework is open-cell foam. This means it has lots of interconnected pores. These pores trap undesirable particles properly.

Home plate withstands temperature levels over 1700 ° C. This makes it excellent for casting superalloys and responsive metals. Its porosity is generally 80% to 90%. High porosity permits good steel flow. It additionally captures even more slag and oxides. Pore dimensions are gauged in PPI (pores per inch). Typical dimensions are 10 PPI, 20 PPI, and 30 PPI. Smaller pores catch finer bits. You select the PPI based upon your steel cleanliness needs.

This ceramic filter is chemically inert. It does not react with most molten metals. This protects against contamination. The plate provides excellent thermal shock resistance. It won’t fracture easily when hot steel hits it. Its strength is sufficient for taking care of. Home plate has a consistent structure. This ensures trustworthy purification performance whenever.

It is widely made use of in factories. It cleans aluminum, iron, steel, and copper alloys. The filter fits conveniently into gating systems. You position it prior to the steel gets in the mold. Unclean steel streams via the foam. Tidy steel appears the other side. This causes higher quality spreadings. Spreadings have fewer flaws. They reveal boosted mechanical homes. Using this filter saves cash. It minimizes scrap rates considerably.

Applications of High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plate

Heat permeable alumina ceramic foam filter layers tidy molten steel. They work well in foundries. Aluminum casting utilizes them a lot. These filters catch unwanted things like oxides and slag. Unclean metal makes weak castings. Filters stop that. Tidy metal flows much better right into mold and mildews. This minimizes scrap components. It saves cash.

Iron and steel foundries require these filters as well. They manage extreme warmth quickly. The permeable framework traps tiny fragments. This prevents flaws in final products. Steel top quality improves significantly. Stronger components result. Filters deal with pliable iron and grey iron spreading. They eliminate inclusions effectively. Surface surface gets better.

Other steels advantage additionally. Copper alloys and zinc alloys utilize these filters. Constant purity issues. Filters provide that. They fit into existing gating systems. Setup is straightforward. Operators change them rapidly. Manufacturing downtime remains reduced. They last with challenging problems. This durability is essential.

The alumina ceramic product stands up to thermal shock. Abrupt temperature modifications don’t break it. Chemical stability is high. Molten steel doesn’t respond with the filter. Pore dimension is regulated specifically. Different degrees of purification are possible. Users pick the best filter for their steel and process. It makes the metal cleaner. Cleanser metal means much better spreadings whenever. Foundries see actual enhancements.

5 FAQs of High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plate

High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plates raise common questions. Here are five key ones answered simply.

What is this filter plate for? It cleans molten metal before casting. Metal flows through its open pores. Unwanted particles like oxides or slag get trapped inside the foam structure. This results in cleaner, higher quality cast metal parts. Fewer defects happen.

How hot can it get? These plates handle extreme heat very well. They work reliably in molten aluminum, copper, brass, and similar alloys. Typical operating temperatures range from 1300°C up to 1700°C. The pure Al2O3 material stays stable and strong even at these intense levels. It doesn’t melt or soften.

How does the filtering work? Molten metal is poured through the plate. The plate has a sponge-like structure with many interconnected pores. These pores create a winding path for the metal. Solid impurities and gas bubbles are too big to pass through the narrow pathways. They get caught within the foam. Only clean metal flows out the bottom.

How long does one plate last? Each filter plate is for one use only. It’s a consumable product. You place it in the filter box within your casting system. After the metal pour finishes, the used plate is discarded. The trapped impurities remain locked inside it. You install a fresh plate for the next casting cycle.

Is the plate fragile? Handle it carefully before use. The ceramic foam structure is strong under compression from the molten metal flowing through it. But it can be brittle if dropped or hit. Always support the plate fully during handling and installation. Avoid impacts or point loading. Proper handling prevents cracks or breakage before the metal pour starts.
