Honeycomb Ceramic Filter Ceramic Honeycomb Body For Steel Industry

 

Product Overview

 

Honeycomb ceramic regenerators, also known as ceramic regenerators and ceramic honeycombs, are key components of regenerative burners and are widely used in industries such as steel, machinery, building materials, petrochemicals, and non-ferrous metal smelting.

 

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 ℃).

Product Picture

 

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.

 

In addition to the honeycomb ceramics used for sintering, honeycomb ceramics that are not sintered also appear, which greatly improves the activity of the catalytic performance. Not only the appearance size has evolved from a small spherical ring shape to large-sized columns and square and round shapes. According to different mold design; honeycomb ceramics with different sizes, different shapes and different structures can be made. For example, the molecular sieve catalyst used in the oil refining air adsorption and drying in the petrochemical industry has a size of up to 0.8m and a width of 0.25m, and the number of holes reaches 25 per square centimeter. There have been great changes in raw materials, processes and machinery manufacturing. Especially the production process has been greatly improved. The honeycomb ceramic used as a catalyst requires no cracking during manufacturing and molding, and the organic components must be released cleanly. In addition to the wear resistance, it also requires a certain mechanical strength and is recycled for many times.
