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, regular in size, and 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

• Plate structure: The main body of the module is in the shape of a plate, with a large heating area and uniform heating. The plate is easy to install and can be hung on the furnace wall, air duct and other locations of industrial equipment to adapt to different spaces.

• Wave-shaped resistance wire: The resistance wire is wavy and mounted on the ceramic fiberboard. This design increases the length of the resistance wire, improves the heating power, dissipates heat more evenly, and optimizes the overall temperature uniformity.

• 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

• Efficient and fast heating: The special design of the resistance wire increases the heating area, and the low thermal conductivity of the ceramic fiber reduces heat loss. It can heat up quickly when started to meet the needs of fast heating process. Shorten the operation cycle and have high temperature rise and fall efficiency.

• Good temperature uniformity: The wavy resistance wire makes the heat evenly distributed, avoiding local overheating or overcooling, and meeting the process with high requirements for temperature uniformity, such as semiconductor chip heat treatment.

• Easy installation and maintenance: plate-type external structure, simple installation, direct external fixing. When the resistance wire fails, it is easy to locate and repair without disassembling the equipment, which improves the equipment availability.

• 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.
