Description
Technical Field
The utility model relates to an industrial kiln field, concretely relates to novel composite installation structure of polycrystalline fiber blanket and fibre module.
Background
The ceramic fiber is a glass fiber prepared by a homogeneous melt under a quenching condition, the diameter of the glass fiber is 2-4 mu m at most, the length of the glass fiber is 30-250 mm, and the glass fiber is stable at normal temperature and has certain strength and elasticity. However, when heated, the glassy fibers are crystallized during particle rearrangement due to viscosity reduction. As the amount of fiber devitrification increases, grain growth and "sintering" from fiber contact causes fiber performance degradation until the fiber structure is lost. Glassy fibers spontaneously crystallize under heat and convert to a stable crystal. The glass fiber has limited use temperature, generally not exceeding 1250 ℃, due to crystallization and grain growth, which causes fiber performance deterioration. Amorphous (glassy) fibers have excellent chemical stability in oxidizing and neutral atmospheres, but have poor chemical stability in reducing, vacuum and kiln atmospheres, containing sulfates, fluorides, alkali metals, V205, etc., and directly affect the crystallization and grain growth rates of the fibers, degrading the properties of ceramic fibers.
Even if the ceramic fiber is pre-compressed and pre-compensated when being made into a fiber module, the safe use temperature of the ceramic fiber is generally 150-200 ℃ lower than the grading temperature under the oxidizing atmosphere, and the safe use temperature of the ceramic fiber is 300 ℃ lower than the grading temperature under the reducing atmosphere and the vacuum environment. And facing to the complicated using atmosphere, the glass state fiber can be spontaneously crystallized when being heated at high temperature, and the surface of the fiber, namely the working surface, can form a powdery layer along with the growth of crystal grains. The air flow velocity of the ceramic fiber module product is generally less than or equal to 25m/s, the ceramic fiber product with the grown crystal grains can be blown and eroded under high-temperature airflow in the furnace, the crystallized fibers lose the original strength, and if the air flow velocity in the furnace is high, the crystallized fibers can fall along with hot smoke to pollute the surface of a heated workpiece.
Special industries, such as daily porcelain, architectural porcelain, electric porcelain and glass industries, are limited by the characteristic that ceramic fiber products are easy to fall off at high temperature, and still use traditional castable and refractory heat-insulating bricks. The traditional refractory product has large heat storage capacity, and compared with ceramic fiber, the heat insulation performance is poor, the heat storage capacity of the kiln body is large, the heat loss is large, the energy is wasted, the operation cost is improved, and the energy conservation and emission reduction are not facilitated. And polycrystalline fiber products are selected, so that the disposable investment is higher and is more than 20 times of the price of the zirconium-containing fiber.
At present, a Chinese patent No. CN203011143U discloses an alumina fiber composite module coating structure for a high-temperature furnace, which adopts a mounting mode of a ceramic fiber module and an alumina fiber blanket to realize the alumina fiber composite module coating structure, but the problem that powder is easy to fall off under the high-temperature condition exists in the patent.
