Abstract

The invention discloses a high-temperature-resistant anti-radiation inorganic coating construction method. The method includes determining the total thickness of the construction coating according to different liner materials and hearth temperatures, performing multiple coating constructions, sintering at the temperature of 500 to 700 DEG C, and forming a high-temperature-resistant anti-radiation inorganic coating. According to the high-temperature-resistant anti-radiation inorganic coating, the heat radiation coefficient of the inner wall of a furnace liner can be increased effectively, the internal radiation heat transferring effect is enhanced greatly, the fine energy saving effect is provided, and the service life of the coating can be prolonged.

Description

technical field [0001] The invention belongs to boiler flue gas treatment technology, and in particular relates to a construction method of a high-temperature-resistant radiation-reflecting inorganic coating. Background technique [0002] The Chinese patent No. ZL201010103489.7 discloses a high temperature resistant anti-radiation inorganic coating and its preparation method. : Through the coating of this patent coating, the blackness of the furnace lining surface can be effectively improved. Since the heating furnace is heated by radiation heat transfer at high temperature, the blackness of the furnace lining is improved, which is conducive to improving the radiation heat transfer of the furnace wall to the furnace. , improve the radiant heat absorption of the heated workpiece, make full use of energy, and achieve the purpose of energy saving. [0003] At present, the general construction process of the surface coating of the kiln lining is as follows: firstly, the surface...
