The furnace kiln lining is made of a plurality of materials, and the high-quality refractory furnace kiln lining is selected according to different furnace kiln working conditions.
In the high-temperature furnace kiln in the prior art, a furnace top with a full-fiber furnace lining is usually adopted, so that a plurality of full-fiber furnace linings are densely distributed on the furnace top, and fiber modules of the full-fiber furnace lining can be solidified and shrunk under a high-temperature state to form gaps among the modules. At present, the normal service temperature of a commonly used zirconium-containing fiber module is 1250 ℃ (the service life of the fiber furnace top is estimated to be 3 to 5 years), when the service temperature is close to or exceeds 1280 ℃, the surface of the module is seriously solidified and shrunk, large gaps are irreversibly generated among fiber modules, the gaps are continuously enlarged along with the service life extension, the gap plugging repair must be carried out by professional construction teams, the furnace is required to be stopped periodically (about 6 months), and the repair difficulty is very high. Because the surface of the fiber module loses elasticity, the fiber blanket plugged between the gaps of the fiber module falls off in the processes of temperature rise and temperature reduction, so that the temperature of the anchoring point rises, the oxidation of the anchoring part is accelerated, and the fiber module falls off, therefore, the fiber blanket can be only temporarily treated even if being repaired, and can be maintained for 3 to 5 months in a production mode.
