Key features

The high-porosity zirconia foam structure effectively removes non-metallic inclusions, slag, and oxides from molten steel, resulting in cleaner metal and higher-quality castings.

Manufactured from premium zirconia material, the filter offers outstanding thermal shock resistance and maintains excellent stability under the extreme temperatures of steel casting.

By promoting smooth metal flow and reducing turbulence, the filter minimizes casting defects such as inclusions and porosity, increasing production yield while lowering scrap and machining costs.

Product Q&A

Q:What is a Zirconia Ceramic Foam Filter?

A Zirconia Ceramic Foam Filter is a high-performance refractory filter designed for steel casting. It removes non-metallic inclusions and impurities from molten steel, improving metal cleanliness and casting quality.

Q:Why is zirconia used for steel casting filters?

Zirconia offers exceptional resistance to high temperatures, thermal shock, and chemical corrosion, making it an ideal material for filtering molten steel under demanding casting conditions.

Q:What are the main benefits of using a Zirconia Ceramic Foam Filter?

The filter helps remove inclusions, reduce casting defects, improve surface finish, enhance mechanical properties, and increase production yield while lowering rejection rates.

Q:What types of steel can be filtered with Zirconia Ceramic Foam Filters?

These filters are suitable for a wide range of steel grades, including carbon steel, alloy steel, stainless steel, tool steel, and other high-quality steel castings.

Q:How does a Zirconia Ceramic Foam Filter work?

Molten steel flows through the filter's three-dimensional porous structure, where inclusions and slag are trapped within the foam network. The purified metal then enters the mold with reduced turbulence and improved flow stability.
