The ceramic fiber module is made by folding and pre-cutting aluminum silicate fiber blanket. According to the requirements, the stainless steel anchors of the corresponding temperature can be installed quickly, conveniently and efficiently. It can be used for the repair of new kiln linings and old kilns.


Ceramic fiber modules are used in RTO furnaces, and generally use a “Bing column” layout-compression alignment along the size of the module. The module is made of ceramic fibers compressed to a thickness of 20 mm and a “U” blanket with a spacing of 500 to 700 mm to compensate for the non-expandable surface of the fibers that may shrink. This structure can avoid the “parquet floor” arrangement, and the fiber module has “flowers” at the corners due to uneven expansion to obtain the best heat insulation effect.

The backing layer of the furnace roof is temporarily fixed by quick card and module installation with fixing bolts. The surface of the aluminum silicate fiber module is brushed twice with hardener, which is resistant to water vapor, and can also resist high-speed smoke flushing to prolong the service life of the insulation.

Stove insulation material:

A. Light weight: The aluminum silicate fiber material special for RTO furnace insulation is a traditional refractory material with a weight of 1/30~1/10, which greatly reduces the weight load insulation structure of the RTO furnace and reduces the engineering cost of the RTO furnace;

B. Low thermal conductivity: The thermal conductivity at room temperature is less than 0.03w/(m.k). It has good thermal insulation effect, better thermal insulation, and keeps indoor heat loss, thereby reducing the amount of auxiliary fuel added and reducing operating costs. The surface temperature of the RTO furnace body is lower and the service life is longer.

C. Good thermal shock resistance: Aluminum silicate fiber has good thermal shock resistance, and can handle the alternating cold and hot caused by the periodic replacement of the inlet temperature of the RTO furnace to ensure a good lining. Lightweight high-temperature aluminum silicate fiber RTO furnace lining has good elasticity. After the pre-pressure installation of the refractory module, the packing belt is hoisted, and then a layer of airtight refractory material is formed, and no expansion joint is required.

D. Strong chemical stability: Aluminum silicate fiber is an inorganic non-metallic material with strong chemical stability.
