1260 Ceramic Fibre Flat Surface Module

1260 Ceramic Fibre Flat Surface Module

The ceramic fiber module is a new type of refractory lining product introduced to simplify and speed up the kiln construction and improve the integrity of the lining. The product is white in color and regular in size, and can be directly fixed on the anchor bolt of industrial furnace shell steel plate. It has good fire-resisting and heat-insulating effect, improves the integrity of kiln fire-resisting and heat insulation, and promotes the progress of kiln masonry technology. . The classification temperature is 1050-1430 °C....

Compared with traditional refractory bricks and refractory castables, refractory fiber materials have the following performance advantages:

a) Light weight (to reduce kiln load and extend furnace life): Refractory fiber is a fibrous refractory material. The common refractory fiber blanket has a bulk density of 96-128Kg/m3 and is folded by fiber blanket. The refractory fiber module has a bulk density of 200 to 240 Kg/m3 and a weight of 1/5 to 1/10 of the weight of the refractory brick or the amorphous material, and is 1/15 to 1/20 of the heavy refractory material. It can be seen that the refractory fiber lining material can realize the lightness and high efficiency of the heating furnace, reduce the kiln load and prolong the life of the furnace.

b) Low heat capacity (less heat absorption, faster heating): The heat capacity of the lining material is generally proportional to the weight of the lining. The low heat capacity means that the kiln absorbs less heat in the reciprocating operation, and the heating rate is accelerated. The heat capacity of ceramic fiber is only 1/10 of that of light heat-resistant lining and lightweight refractory brick, which greatly reduces the energy consumption in the furnace temperature operation control, especially for the intermittent operation of the heating furnace, which has a very significant energy saving effect.

c) Low thermal conductivity (less heat loss): The thermal conductivity of the ceramic fiber material is less than 0.06 W/mk at an average temperature of 200 ° C, and less than 0.10 W/mk at an average of 400 ° C, which is about 1 for a lightweight heat-resistant amorphous material. /8, about 1/10 of the lightweight brick, and the thermal conductivity of the ceramic fiber material and the heavy refractory material can be neglected. Therefore, the thermal insulation effect of the refractory fiber material is very remarkable.

d) Simple construction (no need to set up expansion joints): The construction personnel can be employed after basic training, and the construction technical factors have little influence on the insulation effect of the furnace lining.

e) Wide range of use: With the development of refractory fiber production and application technology, refractory ceramic fiber products have been serialized and functionalized, and the product can meet the requirements of different temperature grades from 600 ° C to 1400 ° C from the use temperature. . Formally, it has gradually formed secondary processing or deep processing products from traditional cotton, carpet, felt products to fiber modules, plates, profiled parts, paper, fiber textiles and other forms. It can meet the demand for the use of refractory ceramic fiber products in different industrial furnaces in various industries.

f) Thermal shock resistance: The fiber folding module has particularly excellent resistance to severe temperature fluctuations. The fiber folding module lining can be heated or cooled at any fast speed under the premise that the heated material can withstand.

g) Anti-mechanical vibration (flexible and elastic): The fiber blanket or felt is flexible and elastic, and is not easily damaged. The installed integrated kiln is not easily damaged when subjected to shock or vibration transmitted by road.

h) No oven required: no oven procedures (eg curing, drying, baking, complex oven processes and protection measures in cold weather) are required, and the lining is ready for use.
