Refractory kiln furniture is a critical component in high-temperature industries. Common materials include silicon carbide (SiC), alumina, mullite, and cordierite, each selected for properties like heat resistance, corrosion resistance, low thermal expansion, or lightweight design. Key types include kiln posts (vertical support), shelves (horizontal load-bearing), saggars (contamination isolation), pusher plates (product transport), and setter plates (direct workpiece holding). These components are widely used in sintering ceramics, glass, and electronics, protecting products from extreme heat while enhancing energy efficiency through optimized kiln design, ensuring both process reliability and product quality.

The perforated Extruded Batts for kilns furniture possess the following product characteristics:

1. Excellent Thermal Insulation Properties
The hollow structure endows them with a relatively low thermal conductivity. This means it can effectively block the transfer of heat within the kiln, playing a crucial role in reducing energy consumption. In addition, it helps maintain a uniform temperature distribution inside the kiln, creating a stable thermal environment that is essential for the firing process. Whether it's ceramics, glass, or other materials being fired, the consistent heat helps ensure the quality of the final products.

2. Lightweight
Compared with solid refractory plates, the hollow ones are significantly lighter. This characteristic brings multiple advantages. Firstly, it simplifies the handling and installation procedures. Workers can move and place them with greater ease, improving work efficiency. Secondly, it reduces the load-bearing stress on the kiln structure. By lessening the overall weight burden, it helps prolong the service life of the kiln, saving on maintenance and replacement costs in the long run.

3. High Strength and Stability
Through rational design and material selection, the hollow refractory plates achieve a balance between light weight and strength. They are engineered to have sufficient strength and rigidity to bear the weight of items even under the extreme heat conditions inside the kiln. This ensures that they won't deform or break during the firing process, guaranteeing the safety and stability of the operation. For instance, when heavy ceramic pieces are placed on them for firing, they can provide reliable support.

4. Good Thermal Shock Resistance
These plates can withstand the rapid changes in thermal stress that occur during the heating and cooling cycles of the kiln. The ability to resist cracking and other forms of damage caused by sudden temperature fluctuations is vital. Thanks to their good thermal shock resistance, they can be reused multiple times, which directly reduces the usage cost. In an industry where cost control is crucial, this feature makes them a popular choice.

5. Good Permeability
Some hollow refractory plates are designed with special air holes or channels. These openings are beneficial for the circulation and exchange of gases inside the kiln. A well-regulated gas flow helps create a more uniform kiln atmosphere. This is particularly important for certain materials that require specific gas conditions during firing, such as some advanced ceramics or specialty glasses. By facilitating better gas exchange, these plates contribute to improving the quality of the fired products.
