It is a kind of porous ceramics similar to foam in shape. It is the third generation of porous ceramics after the development of common porous ceramics and honeycomb porous ceramics.

The high-tech ceramics have three dimensional connected pores, and their shape, hole size, permeability, surface area and chemical properties can be adjusted appropriately. The products are like “toughened foam” or “porcelain sponge”.

Physical and chemical properties:

Advantages:

As a new kind of inorganic nonmetal filter material, foam ceramic has the advantages of light weight, high strength, high temperature resistance, corrosion resistance, simple regeneration, long service life and good filtration and absorption.

Features:

1. Its internal interconnected three-dimensional structure, can be fully embodies its rectification during filtering molten metal, mechanical sieving, “cake”, four filtering mechanism.
2. Adsorption filter material with good chemical stability at the same time, does not react with liquid alloy
3. Effectively remove or reduce the inclusion in the metal liquid, and improve the purity of the metal melt
4. The surface of the cast metal casting is smooth, the strength is improved, the scrap rate is reduced, and the machining loss is reduced
5. Reduce energy consumption, improve labor productivity and reduce costs.

Application:

It is applied to malleable cast iron, ductile iron and gray iron production purification process. Not only can effectively remove the molten iron in various fineness reach micron grade inclusions and part of the gas, make molten iron to produce smooth laminar flow, is advantageous to the flush type, also have good mechanical strength and chemical stability, thermal conductivity, excellent more unique embellish of composition, helps to reduce the friction between the filter and molten iron, ensure smooth filtering.
