Refractory fiber board, also known as ceramic fiber electric heating board. It is a fire-resistant insulation material that does not generate heat. Instead, it serves as a means of providing insulation and protection, mainly by generating heat through the embedded electric heating element on one side. Let's take a look at how to improve the heat transfer ability of the board.
1. Try to use direct open flame heating, immersion combustion and other heating methods to reduce heat transfer frequency and improve heating speed.
2. Waste heat recovery, reducing heat loss, reasonably extending the length of the heating furnace, constructing refractory fiberboard in the preheating section, ensuring that the heated workpiece is preheated during the preheating stage.
3. Install air preheaters and waste heat boilers.
4. Add a multi effect heat reuse series.
5. Increase and arrange heat exchange equipment reasonably, use high and low temperature heating equipment, and improve comprehensive thermal efficiency.
6. When process conditions permit, heat the heated object and increase the temperature of the heat load as much as possible.
7. Reduce the weight of workbenches, fixtures, carts, chain claws, roller tracks, etc. And materials with low specific heat and thermal conductivity, such as fire-resistant fiberboard, are used to reduce their heat storage and ineffective heat during the heating process.
Refractory fiberboard not only has excellent performance in corresponding dispersed fibers, but also has a hard texture, excellent toughness and strength, and excellent resistance to wind erosion. Heating does not expand, lightweight, convenient for construction, and can be cut or bent at will. It is an ideal energy-saving material for kilns, pipelines, and other insulation equipment.
