Embodiment 1

[0040] A ceramic firing kiln quasi-black body group patch 1, which is a refractory fiberboard formed by vacuum suction filtration; the temperature resistance range of the refractory fiberboard is the same as that of the firing kiln, and the thickness of the refractory fiberboard is the same as that of the firing kiln. The location of the kiln pavement is suitable.

[0041] The quasi-blackbody group patch 1 of the ceramic firing kiln is in the shape of a cuboid as a whole, length: 200mm-400mm; width: 100mm-150mm; thickness: 60mm-100mm, and the volume density of the quasi-blackbody group patch 1 in the ceramic firing kiln is 0.28~0.35t / m 3 , The long-term use temperature is 1200 ℃ ~ 1450 ℃.

[0042] A quasi-blackbody group is arranged on the ceramic firing kiln quasi-blackbody group patch, and the number of quasi-blackbody in the quasi-blackbody group is >3.

[0043] The quasi-black body 2 is a through inner cylinder with a diameter of 8mm-22mm.

[0044] Carry out two strengt...

Embodiment 2

[0051] A ceramic firing kiln quasi-blackbody group patch as described in Example 1, the difference is that the ceramic firing kiln quasi-blackbody group patch also includes an accessory assembly connecting piece, and the accessory assembly connecting piece includes A plurality of equilateral triangular refractory fibrous mats are connected and arranged; three through holes 5 are arranged on each equilateral triangular refractory fibrous mat, and the diameter of the through holes 5 is the same as that of a quasi-black body. The hole pitch is the same as the pitch between quasi-blackbodies glued to the quasi-blackbody group patch. (See figure 1 ).

[0052] The regular triangular refractory fibrous mat 4 has a thickness of 20-30 mm and a bulk density of 0.18-0.3 t / m 3 , The side length is 100mm ~ 140mm.

[0053] The felt sheet 4 of described equilateral triangular refractory fiber is carried out twice strengthening treatment:

[0054]Strengthening treatment for the first time...

Embodiment 3

[0060] A kind of paving method of patch as described in embodiment 1, comprises steps as follows:

[0061] 1) Treatment of the furnace lining of ceramic firing kiln: clean the surface of the furnace lining until it is clean and even;

[0062] 2) Paste the patch on the surface of the furnace lining with a high-temperature adhesive; after pasting, the open end of the black body points to the heated ceramic blank in the ceramic kiln.

Abstract

A ceramic kiln standard black body group patch is a flame-retardant fiber board formed through vacuum suction filter molding and is in an overall cuboid shape of which the length is 200-400 mm, the width is 100-150 mm, and the thickness is 60-100 mm. The volume density of the ceramic kiln standard black body group patch is 0.28-0.35 t / m<3>, and the long-term using temperature of the ceramic kiln standard black body group patch is 1200-1450 DEG C. The standard black body group patch adheres to the surface of a hearth lining of a ceramic kiln to form a high-blackness furnace lining. The standard black body group patch is densely covered with more than three standard black bodies, the geometrical shape of each standard black body is an inner cylinder; openings of a black body group all face heated objects in the ceramic kiln; and attachment combination body connection sheets are pasted on paved standard black body group patches in sequence to form black body triads, and the blackness of the pasted black body triads is larger than or equal to 0.98 (1450 DEG C) and is not changed in the using process.

Description

technical field [0001] The invention relates to a ceramic firing kiln quasi-black body group sticker and a paving method thereof, belonging to the technical field of high-efficiency utilization of ceramic kiln energy. Background technique [0002] my country is a major producer and exporter of architectural ceramics and sanitary ceramics in the world. Ceramic firing kilns are key thermal equipment for high energy consumption in ceramic enterprises. The technological progress of ceramic kilns has always been carried out around improving the firing quality of products and reducing energy consumption. , in order to narrow the temperature difference in the kiln, reduce the defects of fired products, shorten the firing cycle and save energy consumption. [0003] Looking at the development history of my country's building ceramics industry, almost all rely on the input of resources to continuously copy and promote, while the contribution of technological factors to the growth is ve...
