Ceramic Fiber Heater Module

Resistance furnaces and experimental furnaces are equipped with ceramic fiber heating modules. If the operating temperature is 800-1000 degrees, ordinary fibers can be used; if the operating temperature is 1200 degrees, high-aluminum fibers or mullite fibers are recommended. The structure is firmly fixed, easy to install, and the components are replaceable.

Ordinary ceramic fiber is also called aluminum silicate fiber. Because one of its main components is alumina, which is the main component of porcelain, it is called ceramic fiber. Adding zirconium oxide or chromium oxide can further increase the use temperature of ceramic fiber.

Ceramic fiber products refer to industrial products made of ceramic fiber as raw material, which are light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical vibration resistance. They are specially used in various high temperature, high pressure and easy wear environments.

Ceramic fiber products are an excellent refractory material. They have the advantages of light weight, high temperature resistance, small heat capacity, good thermal insulation performance, good high temperature insulation performance and non-toxicity.

Aluminum silicate fiber module is used as a silicate thermal insulation material for kiln lining. It also has a certain thermal insulation effect. Therefore, it is widely used in certain special industries. Many people know that the reason why aluminum silicate fiber module can insulate is that it is a thermal insulation material. The following introduces the thermal insulation principle of aluminum silicate fiber module:

1. Since the aluminum fiber porosity of aluminum silicate fiber module is very high, the gas is divided by the fiber into almost stationary small pore bins. At this time, since the pressure in the dispersed multi-pore bins is certain, the air pressure will form a dense shield with the solid fiber to hinder the silica intrusion of hot air flow.

2. Aluminum fiber conducts heat transfer to the thermal insulation of aluminum silicate fiber module. Because the interweaving of fiber blocks has no clear directionality, solid heat conduction can only be carried out along the silica direction of the fiber rod. Therefore, the thermal conduction of the aluminum fiber is not completely perpendicular to the hot surface, and the propagation path is extended. Thermal insulation
