Specification of High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plate

This Heat Porous Alumina Al2O3 Porcelain Foam Filter Plate is essential for tidy steel spreading. It eliminates unwanted pollutants from liquified metals like aluminum and steel. The filter traps oxides, slag, and various other solid bits. This causes exceptional quality castings with fewer flaws.

The plate is made completely from high-purity alumina (Al2O3). This material provides phenomenal thermal stability. It withstands continual usage at temperature levels surpassing 1700 ° C. The filter handles thermal shock extremely well. Unexpected temperature level modifications won’t fracture it quickly.

Its framework features a distinct open-cell foam network. This produces a substantial surface inside the filter. The consistent pore framework is essential. It ensures consistent filtration effectiveness throughout the plate. Pore sizes are available in common grades like 10, 20, 30 PPI. Greater PPI indicates finer pores for smaller incorporations.

The filter plate flaunts high porosity, typically 80-90%. This permits great metal flow prices. It reduces flow limitation while capturing particles effectively. Great mechanical toughness protects against collapse under liquified metal stress.

These filters are dimensionally stable at heats. They won’t warp or reduce substantially during usage. They stand up to chemical strike from most liquified metals and changes. This makes certain reliable efficiency gradually.

Individuals set up home plate conveniently in the filter box within the wash system. It fits basic factory configurations. The filter enhances yield and lowers scrap. It reduces machining expenses later on. Castings reveal much better surface finish and mechanical properties.

The plate comes in numerous standard sizes and densities. Typical thicknesses are 50mm or 75mm. Personalized dimensions are commonly feasible. It requires mindful handling before usage to stay clear of damage.

Applications of High Temperature Porous Alumina Al2O3 Ceramic Foam Filter Plate

Molten metal frequently has contaminations like bits of slag or little fragments. These impurities create significant troubles in completed metal items. They lead to splits, weak points, and other issues. Heat permeable alumina ceramic foam filter layers address this issue. They cleanse the steel efficiently. These filters resemble a rigid sponge made totally of aluminum oxide (Al2O3). The product is really strong and takes care of extreme warmth quickly.

The filter works by capturing unwanted particles inside its complex network of small pores. Molten metal flows right with these open pathways. The impurities get caught within the filter framework. This action results in much cleaner metal downstream. Alumina ceramic is perfect for this severe task. It endures temperatures far beyond 1600 ° C without melting or weakening. This thermal security is essential for filtering system steel, iron, copper alloys, and especially light weight aluminum.

Light weight aluminum factories count greatly on these filters. They place them directly in the course of the molten light weight aluminum circulation. The filter captures oxides and various other impurities before the steel gets in the casting mold and mildew. Steel plants utilize them as well, usually near completion of the production line. Copper and brass suppliers likewise take advantage of their cleaning power. The ceramic foam structure is really difficult. It resists cracking from the intense warm shock when the hot metal strikes it. This toughness implies the filters last much longer and do consistently.

Making use of these filters brings clear benefits. They substantially lower waste from defective castings. The final metal components are stronger and a lot more reputable. Production runs smoother with fewer interruptions. The total top quality of the metal boosts drastically. Shops see better yields and lower prices. The filter’s high porosity allows great steel flow rates. It doesn’t slow down production unnecessarily. Its chemical inertness implies it will not respond with the molten metal itself.

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

What are these ceramic foam filter plates for?
They remove impurities from molten metal before casting. Think aluminum or steel production. The filter traps unwanted particles like oxides or slag. Cleaner metal flows through. This means fewer defects in final cast products. Better quality metal results.

How hot can these filters handle?
They work reliably up to 1700°C (3092°F). Alumina ceramic is very heat resistant. It won’t melt or soften in molten metal baths. This makes them safe for steel, iron, copper, aluminum foundries. High temperature stability is key.

What pore sizes are available?
Common sizes are 10 PPI, 20 PPI, and 30 PPI. PPI means pores per inch. A lower PPI like 10 has bigger holes. It traps larger impurities. A higher PPI like 30 has smaller holes. It catches finer particles. Choose the size based on your metal and impurity level.

How long does one filter plate last?
It depends heavily on usage. One plate usually filters one batch or “pour” of metal. Continuous casting might use one filter for hours. The filter gets saturated with trapped particles eventually. You replace it when metal flow slows down noticeably. Check it regularly.

Can you clean and reuse these filters?
No, they are single-use items. After trapping impurities, the pores get blocked. Cleaning isn’t effective or practical. Trying to reuse a clogged filter risks breaking it. Broken pieces could contaminate your molten metal. Always use a fresh filter for each cycle.
