1. Product Introduction
Ceramic fiber heating module is a new type of refractory product with integrated heating and insulation functions. It uses lightweight high-temperature resistant ceramic fiber (density 300-400kg/m³) as the core substrate. Through the vacuum suction filtration molding process, the resistance wire is embedded inside to achieve the integrated design of heating elements and insulation layers.
It is a new type of refractory lining product launched to simplify and speed up kiln construction and improve the integrity of the lining. It is white in color and regular in size. It can be directly installed according to the size customization, which improves the construction efficiency and has good refractory and heat insulation effects. It improves the integrity of the refractory and heat insulation of the kiln, and the temperature is 1050-1300℃.

2. Structural design and advantages
1. Structural design

• Ceramic fiber matrix: The module uses ceramic fiber as the basic material. This type of fiber has the characteristics of light weight, low thermal conductivity and good chemical stability. The matrix formed by ceramic fiber not only provides reliable support for the internal resistance wire, but also plays an excellent heat insulation role, effectively reducing the heat loss to the outside of the module, greatly improving the thermal efficiency of the module.

• Spiral wire embedded layout: The resistance wire is tightly embedded in the ceramic fiber matrix in a spiral shape. The spiral shape greatly increases the length of the resistance wire in a limited space, so that when current is passed through, more Joule heat can be generated, which increases the heating power of the module. At the same time, this layout allows the heat to spread evenly in the ceramic fiber matrix, reducing the formation of local hot spots and ensuring the stability of the heating process.

• The plate heating module can be matched with the box furnace. The furnace module can achieve zone temperature control, which is conducive to the balance of the overall temperature.

2. Performance and advantages

• Light weight: density 300-400kg/m³

• Low thermal conductivity: 1000℃, 0.23W/mk

• Good energy-saving effect: 10%-30% higher than traditional refractory materials

• High heating efficiency: The spiral wire design increases the surface area of ​​the resistance wire, which can generate more Combined with the low heat dissipation characteristics of the ceramic fiber matrix, the module can heat up quickly, meeting application scenarios with high requirements for heating speed, such as fast preheating of industrial equipment.

• High safety: The resistance wire is completely embedded in the ceramic fiber matrix, avoiding direct contact with the external environment, effectively preventing potential safety hazards such as leakage and short circuit caused by the exposure of the resistance wire, and is especially suitable for working environments with high safety requirements.

• High temperature resistance and long life: Ceramic fiber materials can withstand high temperatures, usually 1200℃ - 1300℃ . Under high temperatures, ceramic fiber provides thermal insulation protection for the resistance wire and reduces its oxidation rate; on the other hand, with its good thermal shock stability, it reduces the damage to the resistance wire caused by rapid temperature changes, significantly prolongs the service life of the heating module, and reduces equipment maintenance costs.

• Flexible customization: supports the production of plate-shaped, cylindrical and special-shaped parts, and matches pit-type furnaces, bell-type furnaces, box-type furnaces and other furnace types.
