Ceramic Filters Have Good Thermal Shock Resistance And Are Used In The Metallurgical Industry
The ceramic filter product is made by a special process and has a foam-like porous structure. It has many advantages such as stable chemical performance, high strength, high temperature resistance, good thermal shock resistance, and large specific surface area. It is widely used in Metallurgy, casting, environmental protection and other fields. It can effectively remove large inclusions in the liquid metal, adsorb small impurities, greatly reduce defects such as trachoma, slag holes, pores, and inclusions, and improve mechanical properties.
The use of honeycomb ceramics is very wide, as follows:
1. Catalyst Carrier
When honeycomb ceramics are used as catalyst carriers, they are mainly used in automobile exhaust purification, boiler exhaust denitration (NOx), industrial exhaust deodorization, and removal of toxic and harmful gases.
The honeycomb ceramic catalyst carrier for automobile exhaust gas purification is mainly a cordierite honeycomb ceramic carrier coated with γ-Al2O3.
2. Refractory kiln furniture
The quality of extruded honeycomb ceramic kiln furniture is 60%-75% lighter than that of traditional kiln furniture. The heat transfer is rapid, which can achieve rapid firing. When it is used to burn ferrite or other electronic ceramics, it is beneficial to improve the performance of the product.
3. Wall flow filter
The porous thin-walled honeycomb ceramics can filter and purify the carbon particles in the diesel exhaust gas (about 500 ℃).

Widely used in steel, machinery, building materials, petrochemical, non-ferrous metal smelting and other industries.
The honeycomb ceramics are composed of countless equal holes of various shapes. The large number of holes has reached 120-140 per square centimeter, the density is 0.3-0.6 grams per cubic centimeter, and the water absorption rate is as high as more than 20%.Due to the characteristics of porous thin walls, the geometric surface area of the carrier is greatly increased and the thermal shock resistance is improved. The meshed pores of the products produced are mainly triangular and square, and the triangular triangle has much better bearing capacity and more holes. This is especially important as a catalytic carrier. As the number of holes per unit area increases and the thickness of the carrier wall decreases, the thermal shock resistance of the ceramic carrier increases, as does the temperature of thermal shock failure. Therefore, the honeycomb ceramic must reduce the expansion coefficient and increase the number of holes per unit area. The coefficient of thermal expansion is the main performance index. The current foreign level is α25-800℃≤1.0×10-6℃-1, which has a certain gap with the domestic comparison, but this gap is getting smaller and smaller. The raw materials for the production of honeycomb ceramics are mainly kaolin, talc, aluminum powder, clay, etc., especially the application of diatomaceous earth, zeolite, expansive soil and refractory materials.
