General Information of Ceramic Foam Filters
Alumina ceramic foam filters are widely used in filtering the alumina and alloys in foundries. With 80-90% porosity, the filters can effectively remove the alumina dross to improve the casting quality.

FAQ
Q1: How do you control the products quality?
A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements. From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control is conducted by workers and then each piece will be sorted and examined by quality supervisors.
Q2: What`s the lead time for my order?
A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks, 10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.
- Q: What are the production methods of calcium silicate board material?
- Calcium silicate (microporous calcium silicate) material and calcium silicate board are produced by static steaming method, dynamic hydrothermal synthesis method and two reaction method.
- Q: Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
- The two are thermal insulation materials. Calcium silicate board strength, cheap, but the use of temperature is not high, the highest 1000 degrees.
- Q: Asbestos free calcium silicate board there is a crack in the kettle, what is the reason?
- Calcium silicate slab blank (blank off off phenomenon is not forming tube adhesion fingerboard blank above)There are two reasons: one is the blank off the vacuum negative pressure is too large, the blank water is too low, low viscosity; two is felt blocked, the billet made worse.The solution is to reduce the negative pressure, strengthen the cloth washing.
- Q: The ceiling of calcium silicate board and mineral wool board which is good
- The fire performance of third mineral wool board no calcium silicate board,Fourth mineral dampeasily yellow, moisture absorption is not good.The calcium silicate board will not have the above shortcomings, the thickness of 15mm if it is the calcium silicate board 4mm ceiling 600*600 thickness can reach the effect of the biggest advantages of mineral wool board, calcium silicate board also is not a burning fire, moisture absorption is very good, green building materials.
- Q: What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!
- Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.
- Q: What are the three major effects of fly ash in concrete?
- Fly ash "micro aggregate effect" in the fly ash particle size is very small beads and debris in cement can be the equivalent of unhydrated cement grains, tiny beads equivalent to nano material and lively, can significantly improve and enhance the structural strength of concrete and improve the homogeneity of products, and compactness.
- Q: What are the new energy-saving building materials? What's new?
- As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.
- Q: What's the use of white portland cement?
- White portland cement as the raw meal with the proper components till the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material. When grinding cement, allow limestone not to exceed 5% of the cement weight. White cement is mostly ornamental, and its manufacturing process is much better than ordinary cement. The gap is mainly used to hook white tiles, is generally not used in the wall, the reason is not high strength. It is available in the building materials market or decoration materials shop.
- Q: What is the main role of fly ash added in concrete products?
- The later strength of concrete can be improved by adding fly ashThe experimental data show that when the concrete is mixed with fly ash, the early strength (28 days ago) decreases with the increase of fly ash content, while the latter strength increases gradually. Fly ash has three effects on the strength of concrete: reducing water consumption, increasing cement content and increasing strength through long-term volcanic ash reactions.
- Q: What is a building energy-saving materials?
- Heat insulation materials and insulation materials collectively referred to as thermal insulation materials.The commonly used thermal insulation material: mineral wool, rock wool, glass wool (in rock, slag as the main raw material, by high temperature melting, made by centrifugal methods such as cotton and thermosetting resin binder insulation products. ) foam plastics and porous polymers, expanded perlite and their products, calcium silicate insulation products, all kinds of composite insulation materials.
